摘　　要：中国经济转上高质量发展阶段,引发更多高素质、有技能的劳动力需求,劳动技能培训是满足这一人力资本需求的重要方式。这同时提出劳动技能培训、人力资本投资如何与收入回报有效互动的问题。为解决劳动力参与技能培训研究中可能存在的遗漏变量和样本选择问题,构建CLDS微观面板数据,采用PSM-DID方法研究技能培训参与者、人力资本投资及其收入效应异质性。结果表明:技能培训能显著提高参与者的收入水平,提高幅度大约为8%;人力资本较高的劳动力参与技能培训的概率更高,产生“择优效应”,而且异质性劳动力参与技能培训所获得的收入效应存在明显差异。为了让技能培训的增收效应惠及更多的劳动力,政府有必要吸引和动员更大面积劳动力参与技能培训。In order to solve the endogenous problems of missing variables and sample selection in the process of labor participation in skill training,this paper constructed CLDS micro-panel data and used PSM-DID method to evaluate the income effect and the heterogeneity of skill training participants through human capital investment.It was found that skill training could significantly improve the income level of participants,with an increase rate of about 8%.Furthermore,this paper finds that the labor force with higher human capital has a higher probability of participating in skill training,resulting in a“merit-based effect”,and there are significant differences in the income effect of skill training of heterogeneous labor force.In order to make the enhancement effect of skill training benefit more workers,it is necessary for the government to attract and mobilize those who have not yet participated in skill training to participate.
