A study on commercial structure of Shanghai based on residents'' shopping behavior
基于居民购物消费行为的上海城市商业空间结构研究

With the launch of system reform since the late 1970s,the urban commercial space went through great changes but with less comprehensive researches.Since the increasingly important influence from the consumers on the system is usually ignored by previous relative papers,the purpose of this paper is to explore the evolution of the central place system from the point view of the corresponding changes of residents' shopping behavior.Taking Shanghai as the city of case study,the research collected the information of residents' daily shopping activities by questionnaire survey which provided the data base.The spatial characteristics of the residents' shopping activity on the aggregate level are generalized,and then further examined by modeling the spatial structure of shopping trip of different commodities;finally,the eight surveyed communities were grouped into three regions according to the income of residents and their spatial structure of residents' shopping activity was explored respectively to see the sub-system shopping centers of different socio-economic areas.The results conform again the hierarchy of shopping trip space of different commodities in previous researches;what's more,it is also found that the condensation of the spatial structure of shopping trip has showed up,which is a reflection of the change of urban commercial system.For the analysis of last part,a hierarchical model of spatial structure much like Davies' "development and hierarchical sub-system shopping centers" is identified.However,we believe that its formation is actually a result of low income residents' moving out and the underdevelopment of the suburban local commence,which is quite different from that of western cities.
