Abstract:

According to the theories of housing search space and anchor point, Internet channels (e.g., housing websites, real estate agents) can provide more housing information (e.g., prices, locations, styles, years, facilities) than traditional channels (e.g., newspaper, TV, advertisements, introduction from friends or relatives) to reduce limitations of previous houses where movers have higher flexibility to choose their new houses to extend search spaces in their moving processes. However, the previous studies usually focused on some factors of residential mobility including housing price, transport, household composition, lifestyle, service facility, neighbourhood environment, employment opportunity, rather than ICT (telecommuting and information channel). Meanwhile, compared with studies on relationships between telecommuting and residential mobility (telecommuters are more likely to make longer moving distance or move into suburban areas because of flexible ways of working, which can reduce limitations of workplace in the moving processes), few scholars have paid their attention to the impacts of information channels on residents' moving space. This paper collected data from the survey of residential mobility in Nanjing city. It mainly used 3D Kernel density analysis to simulate space-time characteristics of different information channel users, and also Multinomial Logistic Regression to demonstrate the impacts of information channel on moving space. Three consequences were found by the above analyses. Firstly, males, young persons, and high-educated and high-income individuals preferred to use Internet channels to collect housing information. Secondly, Internet channel has become the most popular tool for residential mobility to obtain housing information in recent years compared to usage of traditional channels in the earlier times. Finally, more importantly, the Internet channel users were likely to make longer moving distance than the traditional channel users because of more and detailed housing information obtained from websites and real estate agents. On the one hand, these findings can enrich the present studies in the impacts of ICT on moving space in which internet channels take a directive role in the expansion of moving space as well as telecommuting. On the other hand, they are useful to housing information management (e.g., sharing platform building of urban housing information for reducing the "digital divide" among different groups) and housing spatial planning for urban governments (e.g., optimization of urban housing space, especially the one in suburban areas).
