【摘要】 教育通过"人力资本积累"还是"信号效应"影响收入,一直是劳动与教育经济学家所关注的问题,但却没有形成统一的结论。本文利用中国劳动力动态调查2012年数据,以中国学制改革构建准实验设计,分析了教育收益率中"人力资本积累"和"信号效应"的贡献大小。研究发现,根据样本估计的教育收益率约为9.5%,其中约4.0%来自于"人力资本积累"的贡献,约5.5%来自于"信号效应"的贡献。这说明由于信息不完全,在中国劳动力市场上,相对于看不见的"人力资本积累",教育的"信号效应"占据了更加主导的地位。更多还原

【Abstract】 Whether education influences income through "human capital accumulation " or"signaling effect"has always been the concern of labor and education economists,but there is no unified conclusion. Based on the data of China Labor-force Dynamic Survey( CLDS) in 2012,this paper analyzes the contribution of "human capital accumulation"and "signaling effect"in the rate of return on education with the quasi experimental design of China’ s school system reform. It is found that the estimated return on education based on the sample is about 9. 5 percent,of which about 4. 0 percent comes from the contribution of "human capital accumulation "and 5. 5 percent from the contribution of "signaling effect ". This shows that due to incomplete information,the"signaling effect"of education occupies a more dominant position in China’s labor market than the invisible "accumulation of human capital".更多还原
