In the era of globalization and the knowledge economy, talent has increasingly become a strategic resource driving local industrial upgrading and economic growth. Current research on talent mobility has predominantly focused on high-level talents as a collective group or on professional talents within innovative fields, leaving the spatial patterns and mechanisms underlying the mobility of creative talents underexplored. This study investigates the spatial structure and diverse patterns of the mobile network of musical talents in China, utilizing geographical data from 3148 Chinese musicians. Furthermore, it employs Ridge Regression Analysis to identify the key factors that influencing cities' attractiveness to musical talents. The findings reveal the following: 1) Musical talents generally exhibit a high degree of inter-city mobility. The overall mobile network displays a spatial structure characterized by Beijing as the central hub and several economically developed cities as multiple cores. 2) While the mobility networks of musicians across different music genres show certain similarities, particularly in their convergence toward economically developed cultural centers, notable inter-genre disparities exist. 3) Industrial agglomeration is the most critical factor enhancing cities' attractiveness to musical talents, followed by the developmental level and structure of urban economies. Professional music education institutions play a more prominent role in shaping musician flow during the learning stage, whereas the foundation of urban cultural industries and market dynamics exert stronger pull during the working stage.

Taking 115 resource-based cities in China as examples and based on the ERG theory, from the perspective of human needs, this paper first uses the entropy method to measure the supply level of basic public services and the construction level of new urbanization in 115 resource-based cities in China. Then, it applies the configuration analysis method to explore how resource-based cities can promote new urbanization construction by optimizing the supply of basic public services. Finally, according to the urban industrial structure, resource-based cities are subdivided into different categories, configuration analyses are carried out respectively, and policy recommendations are put forward. The results show that: 1) Basic education, culture and sports, medical and health care, labor security, infrastructure and ecological environment are not necessary conditions for the new urbanization construction of resource-based cities. 2) The coordinated cooperation between basic education and labor security plays a crucial role in promoting the new urbanization construction of resource-based cities. 3) In the configuration pattern analysis, the patterns of basic public services in resource-based cities promoting new urbanization construction can be divided into growth-driven type, survival-driven type, relationship-driven type and mixed-driven type. 4) The growth-driven model is applicable to typical and transforming resource-based cities.

In response to the goal of establishing a "24-hour dynamic city" in Shanghai, this paper takes the Inner Areas of the Main City of Shanghai (Shanghai IMC) as a case, obtains the daytime and nighttime population data from 2019 to 2021 based on mobile phone signaling data, classifies four types of urban continuous vitality, namely "continuously active", "daytime active", "nighttime active", and "continuously inactive", and depicts the spatial patterns. The study finds that: 1) There are obvious spatial differences and temporal change in the patterns of urban continuous vitality of Shanghai IMC. 2) The urban continuous vitality of Shanghai IMC is significantly positively influenced by functional diversity, traffic-node density, road network diversity, and spatial proximity.

The cultivation of innovation network is an important factor for anchoring urban innovation space and shaping urban innovation environment. Especially from the micro-subject perspective, it is possible to develop a more profound explanation of the process and mechanism of innovation network formation. Therefore, taking Nanjing as an example, on the basis of identifying the scope of urban innovation space by using patent application data and 'Getis-Ord Gi*' method, we construct the innovation network of Nanjing's innovation space one by one applying the information of cooperative relationship in cooperative patent application data. The results found that: 1) From the perspective of scale type, there are differences in the scale composition of innovation linkages in urban innovation spaces; 2) From the perspective of organisation type, urban innovation space can be divided into core subject discrete, core subject combined, multi-subject discrete, and multi-subject combined; 3) The attributes of innovation subjects are an important reason for the differences in the characteristics of urban innovation space network types, and this phenomenon that can be explained by multi-dimensional proximities.

With the deepening of research on spatial structure and influence mechanisms within urban networks, the investigation of self-organizing mechanisms has become an important research topic. This paper took 336 China's prefecture-level administrative units as research objects, and utilize Internet big data to establish three kinds of urban networks: enterprise organization, information search, and population migration. Then we analyzed the characteristics of physical space and topological structure across these networks, and finally used the exponential random graph model to empirically test both exogenous influencing factors and endogenous self-organizing mechanisms. The research demonstrates that: 1) Three types of urban networks demonstrate spatial heterogeneity in physical spatial patterns, manifesting a "center-periphery" structure across two hierarchical scales: the national level and the regional level (encompassing urban agglomerations and provincial areas). This spatial configuration leads to two hinterland patterns: large-scale interlaced networks and proximity diffusion zones. 2) Topological analysis identifies characteristic scale-free and smallworld properties, with self-organization manifesting at varying scales. As spatial scope expands, triangle and star configurations emerge as dominant factors, driving the transformation of urban networks toward more complex interactive topologies. 3) Urban network arises from the synergistic integration of exogenous influencing factors and endogenous driving mechanisms. The mechanisms of preferential attachment and network proximity collectively elucidate the self-organization process underlying the intricate urban system.

In fact, the consumption scenario of urban tourism attractions has changed from closed scenic spots to borderless tourist spaces. Analyzing the mechanism of tourists' consumption difference under the new consumption scenario from the perspective of amenity can provide theoretical support for cultivating highquality urban consumption space. Specifically, this paper puts forward the method of constructing the consumption scenario of urban tourism attractions, and takes Suzhou Paradise Forest World Scenic Spotas an example to analyze the influence effect and mechanism of urban tourism attractions amenity on the consumption difference between scenic areas and blocks. The results show that: 1) Under the background of consumption upgrading, the consumption scenario of urban tourism attractions has changed into scenic spots and their surrounding blocks, and the tourism consumption is still depressed. 2) Amenity in scenic spots is the continuous driving force of consumption in urban tourism attractions, and its amenity has consumption spillover effect. 3) Block amenity is a stable supporting force for the consumption of urban tourism attractions.

Under the background of innovation-driven development strategy, it is important to guide the highquality development of cities with collaborative innovation. Based on the patent application data of 288 Chinese cities from 2001 to 2020, using exploratory spatial and social network method, this study comprehensively investigates the spatial and temporal evolution of urban collaborative innovation network. The results show that: 1) The scale of urban collaborative innovation has experienced the development stage of "low gradual-steady growth-rapid rise", the proportion of enterprises has been decreasing, but it is still the main force of S&T innovation, the proportion of colleges has been increasing and then decreasing. 2) The distribution of local co-innovation capacity is extremely imbalanced, revealing the pattern of "strong in the east and weak in the west, and higher in the coast than in the inland"; the cross-border co-innovation cooperation is constantly expanding in breadth and depth, and has changed from a "one-line" structure to a "tetrahedron" structure; combined with the intensity of local and cross-border co-innovation, it is divided into four modes: network-intensive, local-prioritized, cross-border-prioritized, and isolated-sparse. 3) The overall network of urban collaborative innovation has changed from sparse to dense, with obvious small-world characteristics; the individual network has been continuously strengthened, featuring a prominent polarization; the network hierarchy has grown progressively, showing a significant "core-edge" structure.

This study from the perspective of proactive urban renewal, a systematic theoretical analysis has been conducted on the direction of urban isolated enclaves and its spatial transformation, as well as the production of cultural tourism space, aiming to explore the path of cultural tourism space transformation from isolation to integration. Specifically, data collection methods such as observation, semi-structured interview, and text analysis were used to empirically analyze the transformation path of cultural tourism space production, taking Huangpu Ancient Village in Guangzhou as an example. The research conclusion is that: 1)Urban villages are urban isolated, which are the fragmentation of organic spatial relationships in the city, exhibiting characteristics of landscape, management, economy, and culture islands. 2)"Power-Capital-Culture" constitutes the fundamental elements of cultural tourism space production in the context of urban isolated enclave transformation,In the production of cultural tourism spaces in Huangpu Village, the logic of power brings about spatial invasion and control, the logic of capital brings about spatial inefficiency and path exploration, and the logic of culture brings about spatial embedding and integration adaptation. 3)"Cultural Tourism+Urban Renewal "is one of the paths for the reproduction of urban isolated spaces represented by Huangpu Village. It regards culture as the core element and uses cultural tourism development as the driving force for proactive urbanization of urban isolated enclaves.

Effective governance is an important basis for the realization of the national rural revitalization strategy, and the institution is the basic element affecting the protection and governance of traditional villages. Using historical data collection, field investigation, in-depth interview and other research methods, based on the perspective of institutional change theory, this paper discusses the internal relationship between institutional change and governance change of traditional villages, and analyzes the evolution characteristics and spatial governance effects of "institutional change-governance change" stage of traditional villages. The results show that: 1) The protection practice of traditional villages in Suzhou has experienced a stage of institutional change characterized by "unidirectional conduction—bidirectional parallel—bidirectional mutual feeding", and evolved in turn according to the governance logic of "unidirectional autonomy—dual co-governance—multiple co-governance". 2)Under the action path of "institutional change-governance change", the spatial governance of traditional villages in Suzhou is advanced according to the logical value of "spatial resource protection—spatial environment remediation—spatial function renewal". 3) We should focus on promoting the bilateral integration of formal and informal institutions, the transformation of flexible co-governance model and the institutional innovation of multi-subject collaborative governance, so as to realize the great governance of traditional villages under the strategic goal of rural revitalization.

The acceleration of the flow of trans regional factors has promoted the edge cities located in the cross-border areas of metropolises to become the outposts for the cultivation of the competitiveness of metropolises. Taking the adjacent areas of Nanjing as an example, this paper conducts a comprehensive investigation on the generation, evolution and reconstruction process of the cross-border edge cities of metropolitan areas. The research first points out that the evolution of Nanjing's cross-border edge cities has gone through four stages: Industrial villages and towns under the diffusion of production factors, single functional areas for industrial development, new towns oriented by residential suburbanization, and social integration under collaborative governance, forming a unique development path with industrial capital as the guide, market capital participation as the support, and social capital integration as the guarantee. Secondly, China's crossborder edge cities have gradually evolved in the process of urbanization construction in edge areas, forming development types such as industrial, residential, and comprehensive. Finally, the research discusses the particularity of Chinese characteristic peripheral cities at the theoretical level, in order to provide inspiration for the integrated development of metropolitan areas.

In this paper, Python code was used to obtain POI data related to post office, postal express and logistics express according to the classification code of Amap, and 10584 logistics terminal network in Chongqing were obtained after screening, then use spatial autocorrelation analysis and disequilibrium index, nearest neighbor index to explores the spatial distribution pattern of logistics terminal network, sorts out the differences in the organization and operation modes of terminal network in Chongqing. This has great theoretical and practical significance for the construction of urban and rural logistics system and the enrichment of urban and rural logistics layout theory, in order to provide strong support for the reasonable distribution of logistics terminal outlets and promote the rationalization of urban and rural logistics distribution system, so as to promote the integration of urban and rural development. The results show that: 1) The distribution of logistics terminal network is uneven in Chongqing, and concentrated in the main city metropolitan area and other areas with high economic level, The spatial distribution of each type of network showed obvious agglomeration characteristics, and the overall spatial distribution showed significant positive correlation characteristics. 2) The clustering degree of various types of logistics terminal network is intelligent express cabinet > third party post station > logistics company direct outlets. 3) The logistics system of Chongqing presents the layout of logistics network at two levels: city-town/village town. 4) The urban and rural logistics transport mode presents integrated development and dual structure coexist.

Housing price are a hot topic of social concern and a crucial factor influencing the settlement and well-being of the floating population. This study examines 41 cities in the Yangtze River Delta region from 2012 to 2018. By employing exploratory spatial data analysis, we investigate the spatial correlation between urban housing prices and the willingness of floating population to reside in specific areas. Through the utilization of spatial panel econometric models and geographically and temporally weighted regression (GTWR) models, we reveal the overall impact and spatial heterogeneity patterns of urban housing price on the settlement intentions of the floating population. The findings are as follows: 1) Housing price in the Yangtze River Delta region exhibit an "east high, west low" pattern, while the settlement intentions of the floating population show a "west high, east low" pattern. Both housing price and settlement intentions demonstrate an upward trend, with increased spatial disparities in housing price and reduced spatial disparities in settlement intentions. 2) There is a strong positive spatial correlation between urban housing price and the settlement intentions of the floating population. However, a significant negative spatial correlation exists between the two factors. 3) Urban housing price have an overall negative impact on the settlement intentions of the floating population. 4) Stable housing price contribute to an increase in the settlement intentions of the floating population, whereas rapid increases in housing price hinder such intentions.

Metropolises, especially the largest part of them, play a vital role in the national development. However, in-depth analyses focusing on the relative collapse of the largest cities compared to the overall city size distribution are severely lacking. Based on the population and build-up data of the Global Human Settlement Layers from 1975 to 2015 and applying the unified definition of cities, this paper explores the extent, causes and mechanism of the size collapse of the largest cities in more than 100 countries. The results show that the sizes of the largest cities in a third of the countries in the world are collapsed, that is lower than its simulated value based on the overall city size distribution. With the increase of the largest cities' sizes, the extent of collapse first deceases and then increases as a result of the dynamic equilibrium between agglomeration economy and agglomeration diseconomy. The application of advanced transportation technology can reduce the size collapse extent of the largest cities. But with the continuous growth of city sizes and exceeding the capacity of transportation technology, the collapse extent of the city sizes will be further enhanced. The findings support the hypothesis that the collapse of maximum city size is attributed to the presence of agglomeration diseconomies and constraints from the technological, economic, and managerial capabilities of large cities within a certain period.

In the era of Internet, the high-speed flows of information contribute to the dynamic reconstruction of urban space. Against this backdrop, this paper constructed China's intercity information network based on the Baidu searching index of 336 cities at the prefecture level and above in 2019, and then applied disparity filter algorithm to extract the backbone of the complex information network and analyzed its structural characteristics. After that, exponential random graph models were used to further explore the underlying endogenous and exogenous influencing mechanisms. The results show that: 1) China's intercity information network is highly dense with full coverage, multiple scales, and obvious heterogeneity. The network backbone extracted by the disparity filter algorithm at the significance level of 0.1 clearly shows the regional disparity and global features of the intercity information flows. 2) The virtual intercity information flows still suggest an apparent gradient difference of regional development. 3) The city's administrative level, informatization level, and tourism popularity can enhance intercity information flows and the provincial boundary effect is prominent in China.

In China, there are a large number of internal migrants circulating from hometown to their destination cities every year. Under the background of New-type Urbanization, the sense of belonging of the migrants, as one of the main bodies of the city, needs to be paid attention to and improved. In view of these, this study takes Shanghai as a destination of case study. Based on the primary data of the suburban residents' behavior survey in 2017, we divide migrants into newcomers (0-5 years), adaptors (5-10 years) and long-term migrants (10 years or above) by residence duration. We compare the level of city belonging of migrants with different residence duration and explore its main influence factors by using the orderly Logistic model. The results show that the city belonging of migrants in the suburbs of Shanghai is mediocre, but there are significant differences in the city belonging of migrants with different residence duration. Long-term migrants show the strongest sense of belonging to Shanghai indicating residence duration still positively affects city belonging of migrants. The time use of different urban spaces significantly affects the sense of belonging of migrants and the effect has population heterogeneity.

The internal migration in China is a two-track system that is composed of the permanent and temporary migration under the hukou (household registration) system. What distinguishes the permanent and temporary migration is not the length of residence at the destination but whether the hukou is transferred to the destination. Migrants have varying degrees of agencies to respond to structural restrictions, producing different consequences of urban citizenship mobility and immobility, which can be observed not only between permanent and temporary migrants, but also within permanent migrants and temporary migrants. How can we understand the urban citizenship mobility and immobility among migrants in Chinese cities? Based on the statistical data of population migration and hukou conferment, the in-depth interviews with hukou migrants and the judgment verdicts of the administrative litigation on hukou disputes in Shanghai, this study identifies five types of mobility and immobility:acquiescent immobility, voluntary mobility, involuntary mobility, involuntary immobility and voluntary immobility. Mobility is highly heterogeneous, different groups of migrants obtain hukou in different ways. Immobility also occurs in different ways. Immobility can be seen not only as an acquiescent or involuntary response under structural constraints, but also as an voluntary or strategic choice.

Based on the 1‰ microdata from 2015 1% population sample survey and the Tencent location migration big data in 2018, this study uses complex network analysis method to compare the spatial structure and organization mode of city networks from the perspective of long- and short-term population flows in China, in terms of nodes, flows, first connections and community structure. The results are as follows: 1) Both long- and short-term floating population tend to cluster in a few large cities, when considering network direction, city nodes are given different functions and roles. 2) Both long- and short-term population flows are mainly distributed in the southeastern half of the Hu Line. 3) Both networks exhibit the dual characteristics of adjacent connection and preferential connection, but large-scale and high-intensity first connections in long-term human mobility network are dominated by adjacent connection. 4) Both networks have obvious community structure, but the long-term human mobility network is dominated by cross-provincial adjacent combination type, reflecting a“clustered”community structure.

There are complex correlations between Contemporary and historical urban elements. From the perspective of space analysis, taking Nanjing as the object, this research materializes the correlations into the spatial relationship between modern public service facilities and historical and cultural resources respectively in individual, unit and overall dimensions from the perspective of "modern-history". The results show that there are different degrees of spatial differentiation in different dimensions and types of facilities, which reflects remarkable rules of individual interaction, unit suitability and overall dependence. By analyzing the formation mechanism, it is found that on the dimension level, the correlations are deeply influenced by the physical geographical pattern and natural evolution, the evolution of urban structure and functional layout, and the profound influence of contemporary urban planning and heritage protection concepts and thoughts. On the facility category level, the differentiation is mainly caused by the different internal correlation logic between different types of facilities and historical elements. The directly related facilities are different because the modern urban elements continue the historical elements, while the indirect related facilities are differentiated by the influence of historical continuity through the medium of modern residential space. Therefore, first, from the static perspective, the modern city shows an obvious continuation of the historical city, and the individual elements of modernity and history have a significant spatial interaction law. Second, from a dynamic perspective, it can be said that spatial evolution is closely related to the evolution of society, politics, economy, system and culture, and all of them have simultaneous and homologous fluctuations and mutations. Third, back to the urban space itself, the current urban space is just a stable system formed by the synchronic coexistence of diachronic elements.

Small and medium-sized cities are an important force for high-quality development. As an important node connecting big cities, small towns and villages, small and medium-sized cities can relieve the development pressure of big cities to a certain extent, radiate the development of small towns and villages, and help avoid "big city disease" and "rural disease". Based on the gravitational field theory, comfort theory and other relevant theories, the evaluation system of urban human settlements attractiveness is constructed by using social statistics data, and the methods of human settlements attractiveness measurement model, spatial correlation analysis and obstacle degree model are used to analyze the temporal and spatial evolution characteristics and obstacle factors of human settlements attractiveness of small and medium-sized cities in Northeast China from 2005 to 2020. The findings are as follows: 1) From 2005 to 2020, the attractiveness of human settlements of small and medium-sized cities in Northeast China presents a gradually rising trend. 2) The attractiveness of human settlements in small and medium-sized cities in Northeast China tends to develop at a high level. 3) In terms of overall characteristics, living environment, population environment and natural environment are the main obstacle factors affecting the attractiveness of human settlements in small and medium-sized cities in Northeast China.

The construction of ecological civilisation requires reflection on the human view of nature and the ethical connection between humans and nature. Urban nature is a space of possibilities for human-nonhuman relationships. Given this, this paper constructs a ternary analytical framework of space, relationship and action to explore the concrete manifestations of multidimensional human-animal relationships in the urban zoo and the forming mechanisms of caring practices from the perspective of care. Using the example of Nanjing Hongshan Forest Zoo, and based on qualitative methods including semi-structured interviews, participant observation and NVivo text analysis, two main findings emerged. First, human-nature interactions and caring relationships need to be conditioned by spatial encounters, and the zoo provides multi-situational encounters. Second, caring relationships lead to demonstrative, responsive and potential caring acts; the spatial encounters, relational connections and caring acts between humans, animals and other natural substances constitute the caring practices for urban nature, thereby further shaping urban natural spaces. In addition, through the cultivation of caring relationships and the demonstration of caring acts, the zoo contributes to the flow of broader social concerns and caring nature practices. This paper reveals the conditions, mechanisms and influences of residents' caring practices for urban nature, infiltrating caring from a nature-managementoriented concept into the everyday practice of individuals, and making caring practices for nature the type of practice that can be more potential in the construction of human-nature relations.

Revealing the mechanism by which basic public service facilities influence residents' satisfaction is not only a key prerequisite for achieving a high level of supply but also an urgent need in constructing people-centered living spaces. This study is based on the theory of "Homo-urbanicus" and constructs a cognitive-measurement model of "human settlement system element-residents' spatiotemporal perceptionresidents' satisfaction." It employs a structural equation model (SEM) to conduct an empirical study using Wuhan as a case example. A total of 1122 valid questionnaires were collected for the study, meeting the data requirements for SEM analysis and demonstrating good discriminant validity and representativeness. Subsequently, a well-fitting structural equation model was constructed, showing strong explanatory power for the theoretical hypotheses. The model validation confirmed the following findings: Firstly, the accessibility, scale, and service quality of facilities significantly and positively influence residents' community satisfaction through mediating factors such as their perception of safety, convenience, comfort, and aesthetics. Secondly, resident attributes and community space attributes exert significant control, with resident age, marital and parental status, community density, and construction era playing a more noticeable role.

Enhancing the vitality of urban public space is an important way to promote the high-quality development of cities and the construction of high-quality living space. This paper integrates the physical and virtual attributes of urban public space, proposes a framework for analysing the vitality of urban public space and an evaluation index system of "obvious and hidden mutual reference", and evaluates the vitality of parks and green spaces in Xi'an based on multi-source big data as an example, revealing the type of synergy between explicit and implicit vitality as well as the mechanism of revealing hidden vitality, thus proposing strategies to enhance the vitality of urban public space. The main conclusions include: 1) both explicit and implicit vitality show the characteristics of comprehensive parks＞special parks＞community parks, the spatial distribution of high and low values of explicit vitality shows the structure of "centre-periphery"; 2) explicit vitality and implicit vitality form four types of high and low values, which are the same as those in other urban public spaces. 3) Hidden vitality has a positive influence on explicit vitality, and user evaluation plays a partly intermediary role in the process of manifestation of hidden vitality.

Advanced manufacturing industry is the main body of the real economy, the carrier of scientific and technological innovation and the basis for concentrating the most active innovation fields and applying innovation to practice. Developing the advanced manufacturing industry is the starting point for implementing the innovation driven development strategy and enhancing national competitiveness, determining the direction of urban development, and playing an important role in depicting the spatial relationship of Chinese cities. This paper uses spatial analysis method and social network analysis method to build China's urban network based on capital flow, and analyzes China's urban network from the aspects of spatial form, overall connection and local connection, so as to draw new findings different from other research perspectives, and provide relevant reference for the spatial layout and development of advanced manufacturing. The research shows that: Firstly, in terms of spatial form, the Chinese urban network based on the advanced manufacturing investment is highly concentrated on the east side of the Hu Line. Secondly, in terms of overall connection, the change trend of China's advanced manufacturing industry investment contact and amount in spatial distance is generally consistent, and the investment connection between cities is mainly concentrated in the distance section of 0-1500 km, accounting for 83.93% and 87.58% respectively. Thirdly, in terms of local links, the complicated and networked investment links have been formed among urban agglomerations and the main structure of the investment network has been constructed, which shows the dual characteristics of medium and long distance directivity and medium and short distance proximity investment links.

At present, China's economy has transformed from a stage of rapid growth to a stage of highquality development. The comprehensive index system of the economic development level of the interprovincial boundary region is constructed, and the comprehensive index of the economic development of each district and county in the interprovincial boundary region of Chinese urban agglomeration is calculated by factor analysis and other methods. Then, through visual processed by origin software, ESDA analysis method and GIS are used to analyze the spatial difference and spatial-temporal evolution of the economic development pattern of the interprovincial boundary regions of Urban agglomerations in China. Finally, geographical detector model is used to analyze the influencing factors of the economic development of the interprovincial boundary regions of urban agglomerations. The results show that:1) The decline process of relative disparity of economic development is faster than that of absolute disparity; 2) There is a strong positive correlation between the level of economic development and the degree of local correlation between provincial boundary regions of urban agglomeration; 3) The local spatial correlation degree of inter-provincial boundary regions of urban agglomerations showed a slow upward trend of decreasing cold spots and increasing hot spots and subhot spots, 4) Provincial boundary regions of urban agglomeration mostly rely on fixed asset investment and government financial expenditure to maintain regional economic development, and reflect the realistic dilemma of limited number of large-scale enterprises and weak regional radiation effect.

Urban shrinkage is a new phenomenon in the current process of rapid urbanization in China. Whether it will have an impact on the implementation of the "people-oriented" new urbanization strategy and the implementation of national land and space planning, and how to respond, has become a key scientific issue to be resolved as a priority in the implementation of high-quality development at the national and local levels in the new era. Based on this, this paper selects three provinces in Northeast China with typical urban shrinkage phenomenon and the most concentrated shrinking cities on the core topic of equalization of basic public services, and carries out the diagnosis of shrinking city effect and the empirical verification of development stage, shrinkage type and spatial distribution. The results show that: 1) The 15 shrinking cities in northeast China show an obvious shrinking effect of basic public service equalization, and the score decreases with the evolution of shrinking development stage, and different development stages show the common characteristics, the level of medical hygiene equality is the lowest and the level of environmental protection equality is the highest. 2) Spatially, it shows the spatial division of "high in the south and low in the north, high in the middle and low in the side"; 3) The evaluation of the basic public services equalization is a result of the comprehensive balance between the total index and per capita index, the "stock" and the "variable" index.

Based on mobile phone signaling data, this study analyzed the overall spatial pattern of commuting in Beijing from three aspects:Job and residence distribution, commuting direction, and distribution of distance and time consumption at the city level. Furthermore, it explored the difference of commuting characteristics in typical employment and residence areas. The main findings are as follows:Firstly, the residential or employment density in Beijing does not completely follow a gradual decrease from the inside to the outside, but is presented as a high-density residential belt and several dot-shaped employment centers; Secondly, two long- distance commuting belts are presented, including one from Changping to Zhongguancun and another from Tongzhou to CBD; Thirdly, for inward and outward relations, there are quite a lot employees in the central city come from new towns of Tongzhou, Daxing and Changping, meanwhile, the three new towns of Yizhuang, Tongzhou and Shunyi also attract a small amount of commuters from the central city; Fourthly, it shows that the people living within West Fifth Ring Road and outside North Fifth Ring Road face higher time consumption per kilometer during commuting, indicating the severe commuting traffic conditions there. Additionally, by comparing the commuting characteristics of residents in five types of residential areas and employees in four types of employment areas, the differences in the spatial patterns of commuter flow in these typical areas have also been found.

Based on spatial production theory, the study examines residents' spatial production practices before and after the renovation of historic blocks through non-participatory observation and in-depth interviews, using the renovation of dilapidated buildings in Tianjin Old City Hall as a case study to reveal the spatial driving mechanisms and root causes of the problems. The results found that:1) Although the abstract spatial representation created by capital is permeating into the everyday living space irresistibly, the indigenous residents have constructed a representational space that supports community life and neighborhood interaction through space competition, creating alternative values and meanings that run counter to the agenda compete for their spatial power to a certain extent, demonstrating the resilience and social imagination of individuals under suppression. 2) After relocation, although the living material conditions have been significantly improved, the inconvenient use of space in the urban fringe area and the unfamiliar neighborhood relationship have caused a strong sense of discomfort, and the identity of the subject has changed to object. 3) The repulsive process of "invasion-resistance-alienation" in residents' living space is the result of the introduction of external elite ideology into local meaning production, and the driving mechanism for the evolution of production methods comes from the interest competition and power game between different subjects.

As entering the phase of high-quality urbanization, promoting internal migrants' mental health has become increasingly important, particularly to the realization of "Healthy China" and "People-oriented" New Urbanization strategy. Using a survey data of 716 questionnaires collected from 61 neighborhoods in Wuhan, central China, this study examines the relationships among environmental perception, life satisfaction and mental health based on the approach of structural equation modeling. This paper contributes to the comprehensive understanding of the mechanisms underlying migrants' mental health, thus helping make effective urban policies. There are four major findings. First, migrants' mental health is greatly influenced by their environmental perception. Second, social support is the most important factor that directly influences migrants' mental health. Moreover, life satisfaction plays a key intermediary role in the impact of environmental perception on mental health. Last but not the least, migrants with different demographic and socioeconomic statuses show different levels of mental health, and their underlying mechanisms are different.

With the rapid development of urbanization, large scales of internal migrants have entered Chinese cities, making the social cohesion among different social groups in urban spaces a heated issue for the society. While researchers have largely focused on the influence of individual characteristics, less attention has been paid to the heterogeneous influence of neighbourhood characteristics on the social cohesion of residents of different social groups. Drawing on the survey data from the 2018 Shanghai Residential Housing Sample Survey and multiple linear models, this study investigates how neighbourhood type, neighbourhood built environment, and location impact the social cohesion of residents, after controlling for residents' individual characteristics. This is followed by the analysis of the interaction effect to explore the heterogeneous influence of neighbourhood characteristics on residents with different hukou. The results show that individual characteristics, including gender, CCP membership, and hukou location have a significant impact on the social cohesion among residents. At the neighbourhood level, compared with commercial housing, a more significant relationship has been found between affordable housing and social cohesion. The perception of better neighbourhood built environment indicated by the perception of accessibility perception, environmental quality perception and public space perception, and objective accessibility has a positive effect on the social cohesion among residents.

Systematically combing and analyzing the collaborative evolution relationship between China's coastal ports and their cities, and putting forward suggestions to promote the coordinated development of China's coastal ports and their cities, has very important theoretical significance and practical research value for guiding the coordinated development of China's coastal ports and their cities in the new era. Taking 20 major coastal ports and cities in China as examples, this paper constructs the synergy degree model of port city composite system, and calculates the synergy degree of port city composite system of two subsystems of coastal ports and cities from 2000 to 2020; DCI model is used to analyze the driving force of the evolution of China's coastal port city relationship, and combined with impulse response to analyze the leading factors affecting the change of port city relationship; Finally, some suggestions are put forward to promote the coordinated development of China's coastal ports and cities. It is found that: 1) Most of China's coastal ports have entered the stage of extremely coordinated development, but the development trend is gradually slowing down; 2) China's coastal port city relationship can be divided into three types: Port driven, city driven and port city mutual drive. 3)We should continuously improve the overall coordinated development level of port city relations in China's coastal areas by strengthening government policy guidance.

This paper elaborates on the urban image in the Internet era. The city image generally reflects people's collective memory of the characteristic elements of the built environment. Image expressions and people's perceptions directly influence regional marketing strategies and urban planning and construction. In the progression of the network society with the deep integration of information technology, various Internet media and "machine eyes" of computer vision algorithms extend the range of human perception, while mobile Internet supports the instant sharing and future vision of the urban environment. The network media superimpose on the traditional experience of the built environment's subjective/objective role in perception, forming a perceptual collage, spatial reconstruction, temporal rearrangement, and cognitive differentiation of city image. By combing city image research in the Internet context, this paper reveals the a priori construction process of city image in the context of the network society, discovers the general rule that hot image nodes deviate from the peak area of urban socio-economic activities, and summarizes how materials such as pictures, texts, and trajectories have applications to city image research in the Internet environment in order to enrich humanistic urban design theory. In conclusion, the creation of city image under the network society should pay attention to the preference of elements of net attractions and the conceptual differentiation of living scenes among various groups of people, discover the common cognition of local culture, and focus on the progression from instrumental rationality to value rationality, which is also an important issue for planning and design in the new era.

City message boards and similar e-government platforms are playing an increasingly important role in urban governance. Taking urban everyday governance as the research object, this study classifies urban problems into four types, namely urban safety, diversity tolerance, living comfort, and ecological livability and proposes a method for spatial identification of urban governance problems based on Natural language processing (NLP) technology and Wuhan's city message board data. The findings show that: 1) Four types of governance problems including urban safety, diversity tolerance, living comfort, and ecological livability all have hot spots. 2) Cold spots of comfortable life problems and diversity tolerance problems are witnessed, mainly located in the core area of the old city. 3) In terms of social-interactive factors, there is a significant difference in the discursive power between children and the elderly. 4) In terms of geographic factors, the rise in population density does not necessarily lead to increasing urban governance problems, which provides evidence for the high-quality governance of high-density cities. 5) Owing to the trend of concurrently developing urban construction and urban quality, the effects of environmental factors on the spatial pattern of urban problems are more complicated than a simple linear relationship.

With all kinds of sports become more and more popular, sports have played an more important role in promoting the process of globalization. Taking the 2008 Beijing Olympic Games and the 2020 Tokyo Olympic Games as the subjects of this study, we investigate the inter-city connections and the world city network formed by them. The results show that: 1) Europe and Asia are the core regions in the process of organising and hosting the Olympic Games, with Europe dominant the affairs of power competition and the continent where the host city is located in has become the most important region for sponsorship and publicity activities, also, a 'triple-polarization' trend were occurred in the affairs of sponsorship activities due to the economic differences between continents; 2) The city nodes and city connections are hierarchical, among which, a five-tier network structure were constructed, and the high-level city nodes include the headquarters of various federations, the cities with top sponsors and broadcasters, and the host cities, while high-level inter-city connections mostly occur between core city nodes in Europe, Asia and North America; 3) Regional city clusters were widely distributed, generally, city clusters were always formatted in specific continents with a few specialized central cities as the core. 4) Despite the impact of the covid-19 epidemic, the host city was still able to enhance the Olympic games' and its own influence by exploring additional individual sports, seeking sponsors and acquiring regional broadcast rights.

This paper interpreted the concept of urban vibrancy on the temporal dimension using mobile signaling data. Researchers construct an evaluation index system that involves the activity intensity, mixing degree and contact strength. Based on this system, this paper summarized five temporal vibrancy modes by analyzing the vibrancy value's 24-hour daily time series clustering. Based on the indicators in the existing literature, 7 first-level indicators and 17 second-level indicators are selected from the two aspects of social economy and built environment, and multiple logistic regression model is used to investigate how influential the socioeconomic and built-environment factors are within different temporal vibrancy modes. Major conclusions indicate that: 1)The temporal vibrancy mode in the downtown area of Nanjing follows five scenarios: a. High vitality with fluctuation, b. High vitality with stability, c. Medium vitality with fluctuation, d. Medium vitality with stability and e. Low vitality with stability. 2) The spatial distribution of different temporal vibrancy modes follows specific patterns. 3) In terms of influential factors, variables including density, the population age structure, community socioeconomic status, transportation location reachability, regional planning functionality, and development intensity promote the generation of high-vitality fluctuating/stable block.

The deepening of aging has brought serious challenges to regional economic and social development. How to ensure the positive and healthy quality of life of the elderly and improve their happiness and satisfaction has become an important research topic. Based on the questionnaire survey data, taking Hefei as the research case, this paper constructs the structural equation model from the subjective and objective aspects, focusing on clarifying the influence mechanism between the objective built environment, the subjective built environment and the living satisfaction of the elderly. The results show that: 1) The elderly in Hefei are satisfied with the community living satisfaction, but there are significant differences in the living satisfaction of the elderly with different individual attributes. 2) The subjective built environment has a significantly positive impact on the residential satisfaction of the elderly (the path coefficient is 0.81), and the impact of perceived characteristics such as community security, aesthetics, traffic accessibility and community entertainment facilities on residential satisfaction decreases in turn. However, the objective built environment has a negative correlation with the residential satisfaction of the elderly (the path coefficient is 0.03). 3) Community neighborhood interaction has a positive impact on the living satisfaction of the elderly.

Spatial structure is the basis for optimizing the regional functions of urban agglomerations. According to the theories of new urbanization and spatial structure, the process of spatial structure differentiation of the urban agglomeration in the Beibu Gulf in Guangxi was studied, with spatial self-organization and inverse distance weighting methods employed. The results showed that: 1) The spatial-temporal differentiation of the scale, attributes and the functions is obvious in the Beibu Gulf urban agglomeration. Its spatial differentiation pattern takes Nanning city as its center and presents itself as a "core-periphery" differentiation pattern. The concentration of Nanning city increased from 34.17% to 44.33%, and the standard deviation decreased from 21.37% to 13.79%. That indicate that the role of large cities in the temporal and spatial agglomeration is gradually expanding. 2) The urban spatial agglomeration and structural differentiation continue to increase. In the past ten years, the concentration of social and economic spatial expansion was 51.85% and 44.12% respectively, while population and land urbanization were only 2.96% and 1.08%. The spatial expansion considering social and economic elements is markedly faster than that of population and land elements, further analyzing the differences in the expansion intensity of various elements, it can be found that the spatial expansion intensity of various elements in recent ten years is ranked from large to small as: Total import and export trade, fixed asset investment, non-agricultural output value, the GDP and total retail sales of consumer goods, and the expansion intensity of other factors is very small. 3) The urban area has the closest relationship with spatial structure. The expansion of investment, trade, the GDP and non-agricultural grows rapidly, while the spatial expansion of population and land elements has lagged remarkably.

At present, improving leisure functions has become the core content of urban construction. As an important part of urban leisure facilities, shopping center plays a crucial role in people's pursuit of a better life. Based on the geographic information data and the data collected from Dianping.com, this paper uses spatial analysis methods and the conditional Logit model to explore the spatial-temporal evolution characteristics and the corresponding influencing factors in Shanghai. Several conclusions are drawn as follows. Firstly, the development process of shopping centers in Shanghai can be divided into 4 stages. In different periods, the axis direction of shopping centers' distribution shows a northeast-southwest trend. As time goes by, the overall spatial distribution pattern of shopping centers tends to be balanced. Secondly, the characteristics of shopping centers' spatial-temporal evolution show both "global decentralization" and "local area agglomeration". As far as global decentralization, shopping centers continue to diffuse toward the outer circle districts, and the density of shopping centers near the central and outer rings has gradually increased. Meanwhile, the statistical gap based on spatial units has gradually shrunk. Considering local area agglomeration, the spatial organization structure of one core aggregation area and four secondary aggregation areas has emerged. Thirdly, market demand, rent costs, transportation accessibility, policy planning, and agglomeration are the main factors that affect the distribution of shopping centers. However, the influencing degree of each factor varies with the development process. For example, since the market had not yet developed, policy planning was of great importance to the location selection of shopping centers during the steady increasing period. In the accelerated expansion period, leisure resources and policy planning had a significant positive impact on the shopping centers.

The popularity of online car-hailing has reshaped residents' commuting behavior, and the urban built environment profoundly affects residents' commuting travel. However, the current academic circles pay more attention to the impact of the urban built environment on traditional commuting modes such as bus, subway, and car. To address this gap in the literature, this paper depicts the spatial differentiation pattern of residents' commuting time and commuting distance on a grid-scale in Haikou and uses Geodetector to analyze the influence of the urban built environment factors and their interaction on residents' commuting travel. The results show that the average commuting time in the morning and evening peaks is 9.01 minutes and 8.79 minutes. Secondly, different built environment factors have distinct effects on commuting time and distance. Thirdly, from the perspective of impact effect, the influence of distance, diversity, design, destination accessibility, and density on commuting time decrease in turn. Finally, superior transportation location, the balance of jobs and housing, high road proximity, and good job accessibility can guide the coordinated development of online car-hailing and diversified transportation.

Taking Lanzhou city as an example, using the pedestrian index to construct an urban living space quality index system from five dimensions of safety, health, convenience, comfort and sociality, the paper investigated on the living space quality of 1,221 residential communities in the city and its social effects. The results showed that: 1) The overall quality of the urban comprehensive living space in Lanzhou was low, with a multi-core spatial structure of "one master twice", and an imbalanced feature of "high in the east and low in the west". 2) Comfort space presented "high value-dispersion, low value-concentration"; convenience space presented a trend of decreasing outwards from multiple centers; health space presented a pattern of "high in the middle, low at both ends, high value eastward"; safety space showed a trend of decreasing from a valley center to the outside; the social space was highly concentrated in the valley center and concentrated in a continuous distribution of low values on the edge. 3) The quality of living space was dominated by medium-quality living space, low-quality living space, and low-quality living space, followed by high-quality living space, and high-quality living space is the least. 4) The differentiation of living space quality in Lanzhou has produced social effects such as inequality of residential housing and isolation from residence, resource mismatch and space deprivation, lack of social trust and social isolation, and accelerated organic renewal of residential areas.

New retail is booming as an important part of smart city. The "new retail" which provides instant delivery service (IDS) has affected the accessibility of urban living service and space-time accessibility in many aspects. Taking the central city of Nanjing as an example, this paper uses the two-steps floating catchment area (TSFCA) method and the coupling-coordination model to calculate the accessibility of online and offline fresh fruit and vegetable stores and analyze the spatial coordination relationship between them. It's found that the online life service obeys the innovation diffusion hypothesis, which strengthens the agglomeration of living service facilities in central urban area. At the same time, the agglomeration and accessibility of online living service facilities are still constrained by the physical geographical space. Online living service is contrary to the efficiency hypothesis and strengthens the spatial differentiation of traditional living services. On the whole, it doesn't improve the supply efficiency and spatial fairness of living services. The results can provide a scientific basis for the configuration optimization of urban living service facilities under the background of Internet development.
