中国教育扩展、教育不平等与收入分配差距间的相互影响

Interaction between China's Education Expansion,Education Inequality and Income Distribution Gap

利用中国1996-2012年数据,建立纳入分布滞后的联立方程组模型,使用三阶段最小二乘法估计教育扩展、教育不平等和收入分配差距间的关系。研究表明：教育不平等对收入分配差距的长期影响为正,收入分配差距对教育不平等的长期影响也为正,其中收入分配差距对教育不平等的影响更大;教育不平等和收入分配差距对教育扩展的影响均为负,其中教育不平等对教育扩展的影响更大;教育扩展对收入分配差距的影响呈倒U型,对教育不平等的影响为负。

Based on the data from 1996 to 2012,in this paper,a simultaneous-equations model that contains distributed lag is set up to analyze the relationship between education expansion,education inequality and income distribution gap by the application of three-stage least squares. The result shows that education inequality has a long-term positive impact on income distribution gap,and income distribution gap has a long-term positive impact on education inequality as well. Income distribution gap has greater influence on education inequality. Both education inequality and income distribution gap have a negative impact on education expansion,but education inequality has a greater impact on education expansion than income distribution gap. The education expansion has an inverted U-shaped impact on income distribution gap,and has a negative impact on education inequality.
