摘要
文章利用中国健康与营养调查数据资料,考察中国城镇教育回报率的变化趋势,重点研究不同教育水平的收入结构和教育回报率结构的变化趋势,并采用相关的计量方法,有效地控制教育和收入的测量误差,以及样本选择性偏差的问题,以期对中国城镇教育回报率及其结构变动做出较为精确的估算。研究发现,在收入和教育回报率总体上升的同时,不同教育水平之间的收入差距和教育回报率差距呈现扩大的趋势;教育测量误差将导致教育回报率的低估;考虑样本选择性偏差的影响得到了高于OLS的估计结果。
Using CHNS data,this paper estimates the tendency of rates of return to education and its structure with effective con- trol on measure errors of education and income and sample selection bias.The results indicate that when both the overall in- come level and rate of return to education raise,income inequalities in different educational levels have an increasing tenden- cy.We also find that measuring errors of education lead to underestimate the rates of return to education,while sample selec- tion bias leads to overestimate the rates.
