摘要
本文运用现代计量方法,在控制了非观测效应的基础上估计了我国1989、1991、1993、1997、2000年的教育收益率,发现:(1)随着改革的深化,教育和劳动市场机制日益发挥重要作用,从1989~2000年,我国的教育收益率迅速提高;(2)非观测效应,以及样本选择偏差和测量误差所引发的内生性问题对结果的影响很大,导致普通最小二乘法低估了我国的教育收益率。
New econometrical methods are used to control unobserved effects and estimate China's return to education in year 1989, 1991, 1993, 1997 and 2000. China's return to education increased rapidly between 1989 and 2000, when labor market became more effective. The study also finds that unobserved effects, sample selection bias and measurement errors play important role on results, and OLS really underestimates yield of schooling,
