Information communication technology is not only an important driving force for the development of contemporary cities, but also of a profound impact on the spatial behavior of urban residents. Based on the analysis of relevant domestic and overseas literatures, combining with urban geography frameworks and urban spatial research frameworks, this paper performs analysis and reviewing from five aspects:Urbanization, urban system, urban activity space (including urban shopping space, urban leisure space and urban living space), virtual space and physical space, and smart city. Furthermore, information communication technologies are of great influence on urban systems and the urban spatial structures in the way of changing mobilities and proximity. At the same time, based on virtual space and physical space, the mechanism of urban space and spatial behaviors of residents under the background of information communication technology is constructed. Under the influence of information and communication technology, the spatial mechanism of city-countryside, city-city and city-region has undergone profound changes. ICT provides power for urbanization through the optimization and upgrading of urban industrial structure, and its path can be divided into industrial informatization and main informatization. With the advancement of new urbanization, the elimination of urban-rural dual structure and the improvement of urbanization quality have become important aspects of urbanization construction, and ICT has also become a key factor in the process of urbanization. Furthermore, the flow space established around the information and communication technology has changed the way of regional and urban connection, and further changed the structure of regional urban functional system. The urban system has undergone scale interactive reconstruction at different levels. On the one hand, the twoway and jumping network flow intensifies; On the other hand, the concept of global city based on global town network is emerging.

This paper makes a relatively comprehensive review of the mobile positioning data-based method innovation and geographical applications of Rein Ahas, a professor of human geography at Tartu University in Estonia. With the rapid development of information and communication technology as well as the largescale usage of mobile phones, mobile positioning data has shown obvious advantages over the conventional data sources like travel diaries, questionnaires, accommodation statistics and census. It has been proved that mobile positioning data can be collected for a much bigger sample of people, a longer period of time and a larger study area, so as to break through the limited spatiotemporal framework. In addition, mobile positioning data can be massive, objective, real-time, accurate and electronically coded, which helps facilitate researchers and urban planners to discover the patterns and laws of human space-time behavior in the daily life. Rein Ahas is one of the first scholars in the world to use mobile positioning data to carry out researches on human space-time behavior. He's also the leader in this field. His researches are experimental and pioneering, showing the valuable exploration made by the international academy in the early stage of understanding and using mobile positioning data. Rein Ahas formally put forward the Social Positioning Method (SPM) in 2005, which provides a new research paradigm for human space- time behavior. Using SPM as the main method, using passive mobile positioning data as the main data source and using geographic visualization as the main analysis technology, Rein Ahas kept participating in the diversified fields of tourism, commuting, transportation, ethnic segregation and smart city.

With the popularity of smartphones and the arrival of mobile Internet era, the mobile map, as a new type, rapidly expanded and influenced resident trip deeply and thoroughly. Hence, through quantitative and qualitative analysis, this study explores the current conditions of mobile map utilization and the diversification among different groups, including the gender, age, education, and economic performance of regions. The data is collected with 444 online questionnaires and 9 specific face-to-face interviews. Specifically, mobile map popularity exaggerates the influence of age, education, and regions, but narrows the gap between female and male. Moreover, this study investigates the influence of mobile map on characteristics of the resident trip, which mainly refers to the trip destination, trip distance, methods, efficiency, group size, and trip frequency. The results indicate that through the indirect impact on the usage differences among people with different personal attributes and direct effect on trip characteristics, mobile map changes traditional resident trip mode and leads to residents' dependence on the information. Mobile map reduces residents' anxiety to strange spaces, cuts down trip costs, and restrains residents' dependence on spatial awareness, making the trip safer and more entertaining, and expanding trip distance. Besides, the huge information coming with the mobile map radically increases trip efficiency and reduces the cost of getting lost, seeking help, and getting stuck in traffic jams. Moreover, the combination of mobile map and social life changes the group size and members. When residents deciding partners, common hobbies, instead of spatial awareness, play a more important role. Overall, the mobile map significantly changes residents' trip mode and the traditional model would no longer meet the needs of the information era.

In recent years, the rapid development of global mobile Internet technology, especially the COVID- 19 epidemic in 2020 has boomed the digital economy industry. "Living on the cloud" and "working through the cloud" have become normal in the pandemic period. Different groups have different opportunities and abilities to use digital resources. The acceleration of digital technology urges scholars to pay more attention to the "Digital Divide" phenomenon and analyze the interaction between "Digital Inequality" and "Social Inequality". Taking five typical urban villages in Beijing as the survey sites, this paper analyzes whether there is a "Digital Divide" between Beijing urban village residents and ordinary urban residents from three aspects of equipment access, network skills and Internet content and how big is this divide:In terms of equipment access, although the proportion of broadband installation of urban village residents is lower than that of urban residents, the Internet traffic and proportion of residents using mobile phones and are close to urban residents and their Internet access cost is lower than the latter. The development of mobile Internet, the popularity of 4G and the rise of China smartphones industry have narrowed the divide in device access between urban village residents and ordinary urban residents. The level of Internet using skills of urban village residents is generally lower than the national average level, but the gap is not obvious. With the improvement of network skills, the deeper the embedding degree of demographic characteristics and socio-economic attributes of urban village residents are, the more obvious the "Information Gap" phenomenon is, which means that the higher the individual's socio-economic status, the more skillfully they can master Internet skills, absorb useful knowledge and avoid Internet traps.

ICT, Information and Communication Technologies, is a new concept of information technology and communication technology. Information technology mainly refers to a variety of technologies used in the processing and management of information, and communication technology is information dissemination and transmission technology. Since the 21st century, ICT has been developing rapidly, and has had a profound impact on the daily life of the residents, changing the daily behavior of residents living, working, shopping, transportation, recreation and leisure, leading to the reconstruction of the spatial characteristics of the residents' daily activities. Based on the analysis of information data and spatial data of female residents in urban villages, this paper explores the activity space under the influence of ICT. The data used in this study are from the survey of residents' lives in Beijing, which was conducted in February to March in 2017. The respondents are located in five city villages. The conclusions are as follows. Firstly, by summarizing the characteristics of the network activities of female residents in the village, it is found that women with demographic and socioeconomic characteristics of young, unmarried, higher educational level and better economic status, are the main group of people who conduct online activities. Secondly, with the help of Stata, econometric models are used to explore the activity space of female residents in urban villages under the influence of ICT. It is found that ICT is not a factor affecting the choice of living space but can reduce the spatial restraint of recreational activities. In addition, ICT provides more employment opportunities for female residents in urban villages, and plays an important role in practical work. The prosperity of online shopping depends on the popularity of ICT, and the complementary effect of online shopping on physical shopping is greater than that of substitution.
