| 内容提要 | 本文从静态不平等与动态不平等间的动态演绎关系出发，构建了公共财政政策、社会流动性与经济增长间的理论模型。理论研究发现，不存在政策干预情形下，静态不平等严格单调递增，即经济体出现典型的“反库兹涅兹事实”；但在公共教育支出政策作用下，随着经济增长，社会流动性改善带来动态不平等下降，促使静态不平等出现先升后降的非对称性特征，这为库兹涅兹曲线的形成原因提供了一种新的视角。实证研究验证了这一结论，并发现不同区域的收入不平等所处阶段有所差异。因此，本文建议政府应充分认识库兹涅兹曲线不能解释中国收入差距的原因，进一步完善公共财政政策以同时改善静态不平等和动态不平等，并针对区域的差异特征实施差异化的公共财政政策，促进库兹涅兹曲线拐点尽快出现。 |
| Abstract | Based on the dynamic deductive relationship between static inequality and dynamic inequality, the article establishes the theoretical model among public finance, social mobility, and economy growth. From theoretical research, the static inequality shows monotone increasing strictly without the policy intervention that is typical anti-Kuznets fact generated in economic entity. However, impacted by the public education spending policy, improvement of the social mobility, associated with economy growth, results in the decrease of dynamic inequality which prompts static inequality reflects the asymmetrical feature. This discovery provides a new viewpoint of the reason the Kuznets curve formed, which is proved by the empirical research. Moreover, it also finds that formation stage of income inequality in different areas exists difference. Thus, the article suggests the government should fully recognize that the reason why Kuznets curve cannot explain the income inequality in China, improving the public finance policy to perfect both static inequality and dynamic inequality then. Meanwhile, conducting the distinguished public finance policies for the difference of areas is essential to accelerate the inflection point of Kuznets curve. |
