外来务工人员收入与教育回报率的性别差异研究

Gender Disparities Between Income and Rate of Return to Education of Migrant Workers

基于2008年全国外来务工人员的调查数据,本文对该群体的收入与教育回报率的性别差异进行实证分析,并在分样本回归中引入z检验通过总样本和分样本回归,本文得出以下三个结论:第一,男性和女性在工资收入方面存在显著的性别差异,受教育年限、工作经验、婚姻状况、务工所在地等对外来务工人员的收入均有显著影响;第二,不论是总样本回归还是分样本回归,不论是以受教育年限还是以教育层次回归,男性和女性的教育回报率差异均不显著,说明性别间的收入差异不是由教育带来的;第三,从受教育层次看,外来务工人员的回报率不是线性递增的,每提高一个教育层次,男性和女性的教育回报率都将大大增加。

This paper empirically examines the gender differences in income,and rate of return to education of migrant workers and is based on national survey data of migrant workers performed in 2008.A Z-test is included in separate regressions for samples.There are three findings in this paper.First,there is a significant income disparity between men and women.Additionally,years of education,work experience,marital status,and work location significantly affect the income of migrant workers.Second,there is no significant correlation between gender and the rate of return to education in total and separate regression samples.Using years of education and education levels as explanatory variables to regress indicates that the income gap between female and male migrant workers is not related to education.Third,the rate of return to education among migrant workers increases nonlinearly as workers obtain higher levels of education.
