中文摘要：

我国城市商业空间结构研究多局限于基于物质空间的中心地体系研究，本文以改革开放后市场经济转型及消费者因素日益重要的零售环境变化为出发点，从居民购物消费行为空间入手，考察目前上海市的商业空间结构特征。本研究基于问卷调查及实地观察所获得的第一手资料，通过经验行为主义方法，总结出上海居民购物消费行为的一般特征，发现上海居民购物出行的空间等级结构较为明显并呈现扁平化的趋势，这与商业中心地的空间结构及其变化是相对应的；此外，本文创新性地得出上海市不同收入地区购物消费行为空间的等级结构特征，并发现了其与戴维斯模型类似的空间特征以及不尽相同的形成原因。

英文摘要：

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 socioeconomic 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.
