基于分位数回归的社会救助再就业人群收入研究

基于问卷调查微观数据，采用分位数回归方法对城镇社会救助再就业人群收入的影响因素进行分析。研究结果表明，一方面，人力资本是社会救助再就业人群收入的主要决定因素，但工作经验回报系数为负值，即人力资本“贬值”，且培训回报率不显著。另一方面，与城镇职工相比，城镇社会救助再就业人群在教育、工作经验、健康状况等方面的回报系数都低于城镇职工；城镇职工“身份”的工资溢价达到12％以上。因此，需要针对城镇社会救助再就业人群采取更有效的扶持政策。

A Study on the Income of Re-employment Group with Social Assistance Based on Quantile Regression

Based on the questionnaire survey micro data, this paper uses quantile regression methods to analyze the impact factors of income of reployment group with social assistance. The results showed that, on the one hand, human capital was the major determinant of income, but the return coefficient of the job experience of re-em- ployment group with social assistance was negative, that is the human capital ＂devaluation＂, and the return rate on training was not significant. On the other hand, in comparison with urban employees we found that, the return coefficients of re-employment group with social assistance were lower than those of urban employees in education, job experience, health status; the identity of the urban employees with a wage premium more than 12%. Therefore, we need to take more effective assistant policies for reemployment group with social assistance.
