A Study of the Income Gap between Urban Workers and Migrant Workers

本文选择2008年社会状况综合调查数据中城市工人和农民工样本,使用布朗分解方法解析城市工人与农民工收入差距,重点解答城市工人与农民工收入差距形成的原因和过程。研究发现单位之间的收入差异是总体收入差距的主要部分,而入职户籍门槛是阻碍农民工进入公有制单位,获取较高收入的重要原因。在同一所有制性质单位内部,城市工人与农民工同工不同酬占总体收入差距比例不大。人力资本差异能够解释收入差距的36.2%,说明人力资本要素虽然能够影响到收入状况,但统一、竞争的劳动力市场并未完全形成。

Based on the 2008 CGSS(CASS) data，this paper uses Brown decomposition method to do the analysis on the income gap formation causes and processes. The study has found that income disparities between the different ownership ( danwei) is the major part of the overall income inequality，and household registration system is the threshold impeding the raise of migrant workers’ income level in public-owned enterprises. Human capital can explain 36. 2% of the income gap，indicating even though the elements of human capital can affect the income，but a unified labor market is not fully formed.
