教育对非农就业工资收入不平等的解释研究

基于分位数回归方法和1989~2009年CHNS的入户数据,根据明瑟方程的回归结果显示,低收入组的教育收益率高于高收入组的教育收益率。通过重新构建的工资不平等程度度量变量和教育不平等以及经验差异度量变量,对离差模型的分位数回归结果显示虽然教育能够提高低收入群体的工资收入,但是教育差距并不能很好地解释收入不平等的扩大。

Research on Interpretation of Non-agricultural Income Inequality from Perspective of Education

Based on the quantile regression method and households survey data provided by China Health and Nutrition Survey(CHNS) from 1989 to 2009,the regression results obtained with the Mincer-type equation show that the earning rate of education for low income groups is higher than that for high income groups.Through reconstructed income inequality degree measurement variables,education inequality and experience differences measurement variables,the quantile regression results from deviation model show that education helps improve the wages of low income groups,but education difference can not account for increasing income inequality.
