高等教育分流对居民收入差距的影响研究

Research on the impact of higher education on income gap between residents

本文采用CGSS2008调查数据,在Heckman计量模型基础上探讨了高等教育分流与居民收入差距互为影响的内生机制,研究表明:两者之间存在的互为影响作用显著。全样本中的职院组和普通大专组表现出人力资本的异质性与教育不平等,对居民收入差距的影响显著。但是在分样本情况下,尤其在城镇样本下,教育分流所导致的职院组与普通大专组在居民收入差距水平上的差异不明显,然而在农村样本上的表现与全样本一致。这说明总体上,职院组比普通大专组在居民收入差距和人力资本存量上劣势明显。

This paper uses the CGSS2008 survey data,based on the Heckman model, the endogenous mechanism of the interaction between the higher education and the income gap of residents is discussed.The research shows that the interaction between the two is significant.Full sample in Vocational Technical College Group and college group showed human capital heterogeneity and inequality in education, had significant impact on the income gap of residents.However, in the case of sub samples, especially in the urban sample, the difference in income gap on the level of Vocational Education Group in college and shunt group was not obvious,however, the performance of the sample in the countryside is consistent with the whole sample.This shows that in general, vocational college group group was significantly better than the disadvantages in the income gap between residents and the stock of human capital.
