职业技能培训对农民工务工收入的影响效应及机制——基于10省调研的经验证据

Influence Effect and Mechanism of Vocational Skill Training on Migrant Workers’ Income: Empirical Evidence Based on Survey of Ten Provinces

基于2020年中国乡村振兴综合调查中10个省份的调研数据,运用基准回归、倾向得分匹配法以及中介效应模型实证分析了职业技能培训对农民工务工收入的影响效应及作用机制。结果表明:职业技能培训有利于提高农民工的务工收入,在排除内生性问题后仍然成立;农民工参与职业技能培训的增收效应存在明显的区域差异,呈现出“东部最强、中部次之、西部最弱”的空间不平衡特征;农民工参与职业技能培训能够提升其就业行业高级化、职位类型高级化和提高就业稳定性,并以此实现务工收入的增长。

Based on the survey data of ten provinces of the China Rural Revitalization Comprehensive Survey(CRRS)in 2020,the influence effect and mechanism of vocational skill training on the income of migrant workers were empirically investigated by benchmark regression,propensity score matching method(PSM)and mediation effect model.The results show that vocational skill training is conducive to the increase of migrant workers’income,and the conclusion is still valid after the PSM method eliminates endogenous problems.Secondly,there are obvious regional differences in the income increase effect of migrant workers’participation in vocational skill training,showing the characteristics of spatial imbalance of“the strongest in the east,the second in the central region,and the weakest in the west”.Mechanism analysis shows that participation in vocational skills training can achieve the growth of migrant workers’income by improving the three mechanisms of advanced employment industry,advanced job type and enhanced employment stability.
