中文摘要：

采用2000年第五次全国人口普查数据库中居民委员会尺度的数据,对转型期上海城市空间重构与分异展开研究.存在6类社会区：计划经济时代建设的工人居住区、外来人口集中居住区、白领集中居住区、农民居住区、新建普通住宅居住区、离退休人员集中居住区.通过计算分异指数,发现当前上海存在严重的住房分异：但并不存在明显的以社会经济属性为基础的社会空间分异.造成这一现象的原因在于计划经济时代的历史以及仍然存在的大型企事业单位对住房的影响.中国城市目前的社会空间分异在程度上与西方城市还有根本的差异.

英文摘要：

Using the 5th census data on the spatial level of neighborhood committee, the lowest administrative level of urban China, this paper examines sociospatial differentiation in post-reform Shanghai. By applying the traditional method of factorial analysis, six types of social areas are identified： worker villages built before reform, migrant communities, professional complexes, peasant villages, new-worker villages and aged accumulated inner-city. Accordingly, the post-reform sociospatial structure of Shanghai is a model combining the three classic structures： concentric layers, clusters, and multi-nuclei. Our findings suggest that residential district （jiedao） is heterogeneous, thus we argue that the social area should be studied on lower spatial levels. In this sense, we further examine to what extent social space is differentiated. It suggests that neither demographic variables nor socio-economic variables have significant differentiation as those in the West; instead, there is rather a high extent of housing differentiation. The underlying reason is attributed to the institutional forces such as work-unit, i.e. their impact upon housing in history and their impact in the post-reform era. This distinctive mechanism indicates that now the extent of sociospatial differentiation of urban China is still much lower than that of Western cities.
