收入差距与教育的逻辑关系解析——基于需求角度的理论框架及实证检验

本文试图从需求层面勾勒收入差距对教育需求分层的影响,通过构建"收入差距扩大--商品需求多样化和商品需求分层--生产要素需求分层--生产要素价格差距扩大--收入差距扩大"的研究逻辑框架,揭示收入差距扩大本身可能通过对商品需求和生产要素需求的影响,表现为一定程度的自我加强的变化趋势.在此基础上,运用宏观数据证实了收入差距的扩大时消费需求多样化和商品分层的影响,发现收入不平等程度的加深确实导致商品消费数量差距的扩大和商品消费价格差距的扩大;并且实证性地检验了在商品多样化和分层的背景下,生产要素呈现出与之对应的分层现象,即表现为劳动力生产要素的收入报酬和教育回报率的差距扩大.

An Analysis of the Logic Relation Between the Income Gap and Education——a Theoretical Framework and an Experimental Test on the Basis of Demand

On the basis of demand, this paper outlines the relation between the income gap and education. The analytic framework is: income gap-demand diversity of products and demand stratification of products-demand diversity of essential factors of production and demand stratification of essential factors of production-a larger price gap of essential factors of production-a larger income gap. We argue that an income gap is more and more self-imposed under the effects of demand of products and demand of factors of p...
