Abstract
Several attempts have already been made to analyze urban activity space, but the datasets employed have typically been neither dynamic nor fine grained. Against this backdrop the mobile phone signaling data is both highly mobile and yet still localizable in space, which makes it a uniquely useful tool for conducting large-scale, representative urban space-time structure research. The development of information communication technology provided an effective approach for the data collection of residents’ temporal and spatial behavior and an opportunity for the transformation of research methods on the interrelationship of the urban spatial environment and individual behavior. This could bring about the opportunity to derive land-use information from mobile phone signaling data. Since China's reform and opening, the cities have experienced a profound change in terms of society, economy, and space, along with the reform of land system, financial system and housing system. Nowadays, China's urban space is still in the phase of reconstruction, which will affect the urban spatial structure and thus the urban activity space. While with the development of globalization and informationization, especially the mobile information and communication technologies have accelerated the changes of people's daily life, which will affect the urban activity space and thus affect the urban spatial structure.
