人力资本、社会资本与收入差距———基于中国城市居民收入的分位回归模型分析

Human Capital, Social Capital and Income Gap: A Quantile Regression Analysis of Chinese Urban Residents’ Income

One of the important issues in academia is that income gap is being kept enlarged in China. Although human capital and social capital are used to explain individual income differences， there is no in-depth analysis of income gap mechanism between social groups. Using the data of Chinese General Social Survey in 2006， the study estimates returns to human capital and social capital by Quantile Regression. It is found that human capital restrains the income gap while social capital enlarges the income gap， which displays“the Matthew Effect”. In order to narrow the income gap of Chinese urban residents， it is imperative to maximize the convergence effect of human capital and minimize the“the Matthew Effect” of social capital.
