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.
