中国劳动力市场收入户籍歧视的无条件分位数分解

The Income Discrimination by Hukouin China's Labor Market—An Analysis Based on Unconditional Quantile Decomposition

使用无条件分位数分解方法对2007年中国劳动力市场的收入户籍歧视程度进行了考察.实证分析的结果显示:从整体上看,2007年户籍歧视可以解释农民工和城镇职工平均收入差距的近三分之一,且歧视效应随收入分位提高而增加;从分项贡献来看,各自变量对收入差异的影响随收入分位变动明显.根据实证分析得出的政策建议为:当政策目标为缩小高收入分位的群体收入差异时,消除户籍歧视的政策效果更好;而当政策目标为缩小低收入分位的群体收入差异时,缩小两群体禀赋差异的政策效果更好.

The income differentials across quantiles between urban workers and rural migrants in China is studied by using FFL decomposition method.The main findings are：Generally speaking,there is significant discrimination against rural migrants and the discrimination increases across quantiles.Meanwhile,independent variables impact the income differentials in different patterns.The FFL decomposition results suggest that diminishing the discrimination could significantly narrow the income gap between the two groups in upper tail,while narrowing the endowments gap could narrow the income gap in lower quantile.
