【摘要】：本文以中国居民收入分配课题组2002年城镇住户调查数据为基础,利用分位回归分析方法讨论城镇居民教育收益率与收入条件分布之间的关联形式。本文的基本结论表明,在收入条件分布较高的分位点上,所对应的教育收益率相对较低,即教育收益率随着收入等级的提高而下降;另一方面,收入函数中引入不同类型的控制变量将会影响到平均的教育收益率估计水平,这也在一定程度上影响到教育收益率的分布特征。就方法论来说,分位回归分析可能为教育收益率估计中如何剔除能力因素所造成的偏差提供了一种解决办法;就政策意义而言,本文的结论表明,教育扩展可能更有利于低收入人口的收入的增长。当然,在施加不同类型控制变量的过程中,我们也发现就业特征对于教育收益率具有非常重要的影响,这不仅表明我国劳动力市场具有分割特性,也可能意味着就业或职业获得成为收入差距扩张的重要因素。
[Abstract]:Based on the survey data of urban households in 2002 by China resident income Distribution Group, this paper discusses the correlation between urban residents' educational return rate and distribution of income conditions by means of quantile regression analysis. The basic conclusion of this paper shows that the corresponding return rate of education is relatively low at the locus of higher income distribution, that is, the educational return rate decreases with the increase of income grade; on the other hand, The introduction of different types of control variables into the income function will affect the average level of the estimated educational rate of return, which to some extent affects the distribution characteristics of the educational rate of return. In terms of methodology, quantile regression analysis may provide a solution to the deviation caused by how to exclude the ability factor in the estimation of educational return rate. Educational expansion may be more conducive to income growth for the low-income population. Of course, in the process of applying different types of control variables, we also find that the employment characteristics have a very important impact on the educational return rate, which not only indicates that the labor market of our country has the characteristics of segmentation. It may also mean that access to employment or occupation is an important factor in the widening income gap.
