空间视角是代际流动研究的重要生长点之一。本文使用CGSS2010—2017年数据，探究了代际流动的地区差异与形成机制。研究发现，我国代际流动水平存在显著的地区差异，呈现“大分散、小集中”的分布态势。决定一个地区代际流动状况的不只是其内部的社会结构特征，还有其外部空间关系，即所处的空间位置和周边的社会资源。周边地区发达的工业化水平、较大的收入离散性以及充足的社会福利资源能够促进本地区的代际流动，呈现 “空间溢出效应”。

Spatial perspective is one of the important growth points of intergenerational mobility research. Using CGSS data from 2010-2017, this paper explores the regional differences and formation mechanisms of intergenerational mobility. The study finds that there are significant regional differences in intergenerational mobility in China, showing a distribution trend of “large dispersion and small concentration”. What determines a region s intergenerational mobility is not only its internal social structural characteristics, but also its external spatial relations, i. e. , its spatial location and the surrounding social resources. The advanced industrialization level, large income dispersion and sufficient social welfare resources in the surrounding areas can promote intergenerational mobility in the region, namely the “spatial spillover effect”.
