The capitalization effect of school quality has always been an important topic in the research field of the impact of public services on housing market. This article takes the main urban area of Guangzhou as the study area, draws on the idea of boundary fixed effects, and matches the houses in the surrounding school districts of 136 key primary schools in 2016 and 2019 with the houses in adjacent non-school districts. The capitalization effect of educational resources of different quality levels is quantitatively measured by using the spatial hedonic price model. The impact of the policy of "same right to rent and purchase" on housing prices and rent premiums in key primary school districts is tested by using the difference-in-differences model. The research results show that: 1) The quality of education in Guangzhou has been partially capitalized in housing prices and rents, and the higher the quality of educational resources, the higher the capitalization degree. 2) The implementation of the policy of "same right to rent and purchase" has not brought about significant changes in housing prices and rental premiums. 3) There is heterogeneity in the impact of the policy on housing prices of key primary schools with different quality levels. 4) There is no significant difference in the impact of the policy on housing prices and rentpremiums of key primary school districts in different regions.

With the rapid development of smart city technology and its full penetration into social life, the traditional human-land relationship has been significantly changed. Owing to the outbreak of COVID-19 and the consequent implementation of lockdown policy, residents' online shopping behaviors have become increasing uncertain, and its characteristics and influencing factors require further study. Based on questionnaire survey data of Weifang city, this study investigated the characteristics of residents' online shopping behaviors during the epidemic period and their differences from usual. Structural equation modeling was further used to explore the influencing factors of residents' online shopping behaviors during the epidemic period. The results showed that residents' online shopping frequency, expense, and duration were higher than the peacetime. Moreover, during the epidemic period, residents' online shopping frequency, expense, and duration all decreased from the central city to the suburbs, which was in line with the technology diffusion hypothesis. Online shopping attitudes during the epidemic period had a significantly positive impact on residents' online shopping behaviors; In-store shopping behaviors during the epidemic period promoted online shopping behaviors; Residents with high income, high education level, longer online shopping years and better living location were more inclined to online shopping.

The social space of urban China has been experiencing dramatic reconstruction in the transitional period, this is also a microcosm of the unbalanced and inadequate development in urban space. Complete empirical research will be helpful to facilitate the understanding of an abstract issue regards to the intra-city spatial equality, which further provides scientific consulting for decision making. Based on population, POI, medical facilities information and other sources of data, this paper takes Shanghai as a case and brings the scene of the hierarchical diagnosis and treatment system together, to assess the accessibility of medical facilities by the two-step floating catchment area method, and calculates the disparities of accessibility among different groups. The results indicate that the hierarchical diagnosis and treatment system has improved the extent of medical service coverage of the whole Shanghai greatly, and alleviated the imbalanced status between the central city and the suburbs significantly. However, the so-called "policy dividend" is usually be helpful for the socially advantaged groups; as for the marginal groups, such as the migrants, low educated group, manufacturing workers, and renters, their unequal status has no significant changes.
