移民对本地居民社会信任的影响：来自中国大规模人口迁移的证据
The Impact of Immigration on Social Trust of Natives: Evidence from the Mass Migration in China
摘要
This paper examines the impact of immigration on natives' social trust in the context of China's mass internal migration. Combining individual-level information on social trust and county-level information on immigration rate, we employ the instrumental variable strategy and find that immigration has a significant negative impact on trust among native residents. The impact of immigration on trust is more salient for trust in weak ties than trust in strong ties, and from a compositional perspective, the impact of low-skilled immigrants is more salient than that of high-skilled immigrants. Additional analyses suggest that better public services can buffer the impact of immigration on trust, implying a key role in public policy.

本文以中国大规模内部人口迁移为背景，考察移民对本地居民社会信任的影响。通过结合个体层面的社会信任数据与县级层面的移民率信息，采用工具变量策略发现：移民对本地居民的社会信任具有显著的负向影响。从信任类型来看，移民对弱关系信任的冲击强于强关系信任；从移民结构来看，低技能移民的影响比高技能移民更为显著。进一步分析表明，更优质的公共服务能够缓冲移民对信任的冲击，这揭示了公共政策在此过程中的关键作用。
