摘要: 文章运用倾向值贪婪匹配、倾向值最佳匹配、倾向值加权和匹配估计量等4 种倾向值分析方法,研究了流动人口正规就业与非正规就业之间的工资差异。结果表明,流动人口的受教育水平、工作经验等个人禀赋在正规就业者和非正规就业者之间存在着显著差别。当这种选择偏差存在时,t 检验和OLS 回归会高估正规就业对工资水平的平均干预效应。在控制选择偏差以后,正规就业与非正规就业之间仍然存在着显著的工资差异。这说明流动人口劳动力市场存在着正规就业和非正规就业的市场分割和对非正规就业者的歧视。

Abstract: Using multiple propensity score methods,including propensity score geedy matching,propensity score optimal matching,propensity score weighting and matching estimator,this paper analyzes wage differentials between formal and informal employment of migrant workers. The results show that the two groups of migrant workers differ significantlly in education,work experience and other personal chracteristics.Resulting from these selection biases,the t test and the OLS regression would overestimate the average treatment effect of formal employment on wage. After controlling the selection biases,there are statistically significant wage differentials between the two groups,which confirms the market segmentation between formal and informal employment and the discrimination against informal employmee in the labor market of floating population.
