教育不平等与收入分配差距:中国的实证分析 总被引:1,自引:0,他引:1
Based on the endogenous growth theory, this paper uses the Gini coefficient to measure educational inequality and studies
the empirical relationship between educational inequality and income inequality through a simultaneous equation model. The
results show that: (1) Income inequality leads to educational inequality while the reduction of educational equality does
not contribute to the decrease of income inequality, and there is no simple casual effect between them. However education
expansion is beneficial to reduce educational inequality and income inequality. (2) Education relates to income inequality
through the human capital transmission mechanism, but this mechanism does not automatically translate into a virtuous cycle
of “educational equality↔income equality”. (3) In the long run, the reduction of educational inequality does not reduce income
inequality, but income inequality has a negative instant-impact on educational equality. (4) At present, the level of educational
investment and urbanization do not effectively promote educational equality. In addition, the robustness of the model used
in this paper has been partly proved.
