收入分配长期演化趋势的经济学分析--推进库兹涅茨倒“U”型假说

The Economic Analysis on Evolution of Income Distribution:To promote the Hypothesis of Kuznets Inverted "U" Curve

纵观关于收入不平等长期演化趋势的研究,无论在经验研究和理论研究方面都存在着分歧,尤其随着近年来数据可获得性的提高,以及更新颖的计量方法的使用,许多案例和经验研究发现收入不平等的长期演化趋势远比库兹涅茨倒"U"假说所描述的情形更为复杂,甚至出现某种周期性变化特征。而对最近这些经验研究结果,相关理论研究文献并没有给出明确的回答。本文通过构建数理经济学模型的方式,尝试从理论上对这一问题进行探讨。

When we check the literatures with panoramic view on income inequality long-term evolution research,we find differences between empirical studies and theoretical research respects. Especially in recent years as more datas ,as well as more innovative econometric methods are used,the number of cases and experience studies find that the evolution of income distribution show more complex pattern than the situation described by the Hypothesis of Kuznets Inverted 'U' Curve.But existing theoretical literatures can not give a convincing explanation for these new findings of recent empericl literatures. This paper aims at answering the question from a new perspective by constructing a formal theoretical model.
