教育的同型婚姻与中国社会的家庭工资收入不平等:1996—2012

摘要/Abstract

摘要：

近年来，关于同型婚配的研究在社会学界得到越来越多的关注。本文采用LHSC1996与CGSS2012两个截面数据，首先用对数线性模型测量调查数据中夫妻教育匹配的同型程度，用相关系数测量工资收入上的相似程度。然后使用模糊置换检验估量在控制年龄、城乡和地域之后，夫妻受教育程度的匹配对家庭工资收入不平等指数泰尔指数（Theil Index）的影响，并通过比较两个截面数据考察其变化趋势。在研究方法上本文有所贡献，本文所使用的改进的置换检验方法可以更好地控制年龄等定距变量。

Abstract:

In recent years,research on assortative mating and educational homogamy has attracted much attention in sociology. This paper,adopting LHSC1996 and CGSS2012 cross-sectional data,first uses log-linear models to measure educational homogamy and Pearson's correlation coefficients to measure earnings correlation between spouses,then uses fuzzy permutation tests to measure the contribution of educational homogamy towards earnings inequality,in terms of the Theil Index,controlling for age,province and hukou status. Comparing results from two years,this paper reveals that the trend of said contribution. First,CGSS2012 shows an elevated family earnings inequality in total,and pairing over all dimensions discussed contributes more to inequality than before. Second,pairing over all dimensions discussed show similar contributions to earlier counterparts,except for a difference in extent. Third,educational pairing contributes significantly more to inequality in CGSS2012. Its main effect and net effect controlling for aforementioned covariates are both positive,which means educational homogamy increases family earnings inequality. This paper contributes to empirical knowledge as well as methodical advances. We have concluded that fuzzy permutation tests can include continuous variables.
