摘要
许多学者通过实证研究发现部分人力资本变量对农民工的非农收入没有影响甚至是负影响,与传统人力资本理论不一致。通过对安徽省合肥市农民工市场的调查分析得出:培训变量对农民工非农收入的影响异于人力资本理论是因为当前农民工培训质量不高,培训没有使农民工掌握一门真正技能所致;健康变量对农民工非农收入的影响不同于人力资本理论是因为在抽样中存在选择性偏差所致。文章在不掌握全体样本信息的条件下,使用截面回归模型和相关统计方法对上述推论进行了验证,结果支持上述推论。
Academics argue, through empirical studies, that some variables of human capital have no or even negative impact on off-farm income of migrant rural workers, which doesn＇t comply with traditional human capital rationale. Based on a survey of labor market of Hefei migrant rural workers, this paper concludes that the discrepancy between training variable＇s impacts on off-farm income of migrant rural workers and theory of human capital can be attributed to that training is not good enough to make migrant rural workers acquiring a skill. The paper also finds that the discrepancy between health variable＇s impacts on off-farm income of migrant rural workers and theory of human capital can be attributed to the sample selection bias. With insufficient sample information, the paper testifies the above deductions with section regression models and statistical methods,and the result is in favor of the deduetions.
