我国教育扩展对收入差异的影响预测

The Influence of Educational Expansion on Income Difference in China Currently

使用2006年的中国健康与营养调查(CHNS)数据,采用总体回归和分阶段回归方法,对分层教育收益率进行比较分析。结果表明,非义务教育阶段的教育收益率高于义务教育阶段的教育收益率;在初中受教育水平和高中受教育水平的人群中,较贫穷者的教育收益率高于较富裕者的教育收益率。因此,如果实施教育扩展计划,延长义务教育年限,让较贫穷者能够接受更高层次的教育,会明显提高他们的收入水平,这样既能提高经济效率,又能有效解决收入差异过大问题。

Using the method of general regressions and quantile regressions on the Chinese health and nutrition survey （CHNS） data in 2006, we make a comparative analysis on the return of schooling in stages. Results show that the return of non-compulsory education is higher than that of compulsory education; the schooling return of the poor is higher than that of the rich in the sample of the educational level of middle school. Therefore, if the government implements the plans of compulsory education expansion to give the poor people more edueational chance which will raise their incomes obviously, it can improve economic efficiency, and effectively solve the problems of large income difference.
