5219社会网络作为提高居民福利和促进经济增长不可忽视的非市场力量，是否也可以促进代际收入流动呢？文章基于中国家庭追踪调查数据，采用父代与子代的收入百分位排序关联系数衡量代际收入流动，从社会网络规模、强度和工具性三个维度综合测量社会网络，实证研究了社会网络对代际收入流动的影响及其机制。研究发现，社会网络显著促进了代际收入流动，且使用父亲在1966−1976年间的家庭成分作为工具变量消除内生性后这一结论依然成立。这种影响在市场化程度较低的地区、女性和低收入家庭中的作用更为明显。进一步的研究表明，社会网络通过加强信息共享、降低信贷约束和改善子女就业等渠道促进了代际收入流动，且社会网络的三个维度在不同渠道中发挥的作用也存在差异。
