基于上海的调查分析,在因子分析的基础上将ESDA方法应用于社会融合水平研究。运用全局Moran's I指数、热点分析、空间回归等指标和模型,从全局和局部两个层面研究了城市外来人口社会融合水平空间差异及影响因素。结果表明:从总体上看,上海外来人口社会融合水平较高,但各个区县差异较大;从局部上看,中心城边缘区社会融合水平较高且内部存在关联性,形成了显著的"热点"区域;空间地理因素和制度因素对外来人口社会融合水平空间差异有显著影响,其中公共服务支出、社会保障支出两个因素作用最显著。

Against the background of the process of urbanization of China, huge amount of floating population poured into the city, especially in large metropolitan areas like Shanghai. Thus the social integration of the floating population is important for both large metropolitan areas and recurrent population. In order to make an overall and systematic analysis, this research is based on the results of investigation in Shanghai. The research mainly concerns on social integration, which applied ESDA method and factor analysis as well. We try to use multiple kinds of index and methods, such as Moran I, hot spot analysis, spatial regression, in order to have a deep and comprehensive understanding on the characteristics of migrants' social integration, as well as the important dynamics behind the phenomenon. The research concludes that, in general, obvious homogeneity, which means the same tends to gather, is found in migrants' social integration. But the discrepancy has emerged in different district and counties. On the other side, according to the data in Shanghai, "hot spots" areas appear at the borders of the central district of a base area, where the social integration index is highly related as well. However the migrants' social integration in Shanghai has no distinguished cold spot in spatial yet. The social integration in these areas is influenced by many factors. As to the dynamics, spatial and institutional factors play a vital part in the whole process, which the degree of satisfaction on public services and the social insurance expenses as well as participation in social insurances matter most.
