Coefficient of educational homogamy, by province.

This paper examines the effect of educational assortative mating on overall income mobility in terms of both inter- and intragenerational mobility. In recent years, educational assortative mating has become a trend in China, and this marital sorting pattern not only contributes to marriage stability but is also related to increased income mobility. Educational assortative mating affects the distribution of educational resources among families with diffferent educational qualifications. Families with higher educational qualifications have more educational resources, thus obtaining a more solid income status. Educational assortative mating has the most significant influence on the income mobility of the low-income group, as high-quality educational resources are the key to enabling this group to raise its income status. This paper argues that, in the future, income mobility should be promoted by evenly distributing social education resources and reducing the resource constraints on the upward mobility of the low-income group.

本文从代际与代内收入流动双维度出发，探讨教育同配择偶（educational assortative mating）对整体收入流动性的影响效应。近年来，教育同配择偶已成为中国主流的婚姻择偶趋势，该婚配模式不仅有助于增强婚姻稳定性，同时亦与收入流动性提升存在显著关联。教育同配择偶会影响不同学历家庭间的教育资源分配格局。学历层级更高的家庭拥有更为充裕的教育资源，进而能够稳固自身的收入阶层地位。教育同配择偶对低收入群体的收入流动性影响最为显著，优质教育资源正是该群体实现收入阶层跃升的核心依托。本文提出，未来可通过均衡分配社会教育资源、纾解低收入群体向上流动面临的资源约束，以推动整体收入流动性的提升。
