城乡一体化进程中我国流动人口的教育回报与工资收入差距的分解

摘要

本文利用中国居民收入项目调查组提供的CHIP数据流动人口卷,基于明瑟方程,采用多种微观计量方法,实证研究了流动人口的教育回报与工资收入差距的关系,结果表明:流动人口的教育年限、工作经验与工资水平呈正相关,人力资本存量越高工资收入则越高;教育回报的异质型收益特征在不同收入条件下呈"W"形分布,低、高收入群组的教育扩展具有最强的增收效应,但遗漏先天禀赋则会造成教育回报的内生性低估;人力资本存量的个体差异是造成流动人口工资差距的主要原因.基于流动人口的教育回报与工资收入差距,本文为进一步缩小流动人口组内工资差距提出相应的对策建议.%This paper based on the CHIP data provided by the survey of income of residents in China,u-sing Mincer equation and micro metering method to discuss the return on education and decomposition of wage income gap of migrant Chinese.It is indicated that there is a positive correlation relationship be-tween income and human capital,improving the level of education make contributions to enhance individ-ual's income;heterogeneous educational returns show "W" in the regress of quantile,the enhancement of educational level has the strongest effect on income increasing,which located in income distribution at the both ends,but the omission of innate endow ments leads to an underestimation of the endogeneity of educational returns;the individual difference of the stock of human capital is the main reason which leads to the wage income gap of migrant Chinese.On this basis,we put forward some countermeasures and suggestions to further reduced the wage income gap of migrant chinses.
