周云波教授的论文(以下简称周文)利用1978年至2006年的时间序列数据对库兹涅茨倒U假说进行了经验检验。周文的第一部分致力于理论分析,其构建的理论模型简洁明快,逻辑自洽。在假定城镇和农村内部的收入分配完全均等以及城镇人均收入高于农村人均收入的情形下,推导出了从农村到城市的人口流动会导致基尼系数出现倒U形的变动。这一结论令人 Professor Zhou Yunbo’s thesis (hereinafter referred to as Zhou Wen) empirically tests the inverted U-hypothesis of Kuznets using the time-series data from 1978 to 2006. The first part of Zhou Wen is devoted to theoretical analysis. Its theoretical model is simple, concise and logical. Assuming that income distribution within urban and rural areas is completely equal and urban per capita income is higher than rural per capita income, it is deduced that population flows from rural to urban areas lead to an inverted U-shaped change in the Gini coefficient. This conclusion is impressive
