新千年来，中国城市全球化进程加速。北上广跻身世界城市体系排名前50位，吸引了越来越多的跨国移民前来就业、生活，在城市内部形成了移民集聚区与社会空间分异现象，甚至引发了移民与本地社会的冲突。移民融合因此成为现实热点，而现有研究揭示出三对矛盾：融合的复杂性与可测度性之间的矛盾；跨国移民的高流动性与日常生活的在地性之间的矛盾；移民社区管控与移民社区塑造之间的矛盾。针对这些矛盾，本项目以广州典型跨国移民社区为案例，基于移民个人日常行为实践，采用定量模型和质性研究方法，重新解读社会融合的内涵、机制和空间效应。首先，选择多尺度（族群/个人）和多维度（功能/文化/空间等）的分析框架，测算移民融合程度；其次，系统分析移民的社区日常生活，诠释日常行为对融合的作用机制；再次，在融合过程中，探讨跨国移民对社区空间的塑造效应。通过理论探索，本项目拟揭示出跨国移民融合的可行路径，为城市政府的移民管治提供政策参考。

Since the new millennium, the role of Chinese cities in World City system has been remarkably increasing along with the process of globalization in urban China. Against this context, more and more transnational immigrants work and live in China’s World Cities like Beijing, Shanghai, and Guangzhou (ranked Top 50 in the World City System). They are inclined to concentrate in some specific urban areas, producing segregated immigrants’ neighborhoods; and even, this social-spatial segregation results in serious conflicts between immigrants and natives. Immigrants’ social integration thereby becomes a hot topic, with both scientific relevance and social implication. In the literature, existing studies have outlined three pieces of paradoxes in social integration: the complex of social integration vs. its uniformed measurement, immigrants’ frequent mobility in the globalization era vs. their groundedness in daily life, and the regulation of the government on immigrants’ neighborhood vs. immigrants’ spatial practice in the neighborhood. Coping with these three problems, this project tends to revisit the meaning of social integration, its mechanism of and the spatial outcomes of social integration, by employing the empirical studies of typical transnational immigrants’ neighborhoods in Guangzhou. The emphasis is on the perspective of immigrants’ social integration through their daily-life activities, with quantitative modeling, qualitative methods and daily-activity mapping. More specifically, it proposes three major questions: first, how to measure the different scales (agglomeration-level and individual-level) and different dimensions of immigrants’ integration (functional, cultural, economic, psychological), and what are the determinants; second, what are the effects of immigrants’ daily life activities on their social integration in the neighborhood, and what is the dynamics; third, in the process of social integration, how do immigrants produce the urban space of the neighborhood, and what are the spatial outcomes. Based on these three theoretical issues, this project plans to outline China’s approach for the integration of transnational immigrants, and also to provide the municipal government with the policy implication of immigrants’ neighborhood governance.
