基于省际面板数据的行业收入差距与经济增长关系研究

通过泰尔指数的测算发现,中国的行业收入差距水平9年间几乎没有变化,然而各地区的行业收入差距变化差异较大,发达省份的行业收入差距持续扩大,欠发达省份的差距持续缩小,全国的平静掩盖了各省行业收入差距变化较大的事实,更值得一提的是,中国各地区的行业收入差距的变化规律违背了"库兹涅兹倒U型假说"。基于30个省份19个行业的省际面板数据,建立计量模型来分析各地行业收入差距与经济增长的关系,结果表明,各地经济增长与行业收入差距呈现负相关关系,而且这种关系是互为因果的。

The Study of Relationship between the Income Gap and Economic Growth Based on Provincial Panel Data

We found that the income gaps between the industries have not nearly changed during the past 9 years, but it changed a lot in different parts of China. The gap kept expanding in developed areas and kept decreasing in developing areas. The average numbers cover the huge gap of various areas. Further more, the variation in China contrary to ＂the hypothesis of Kuznets＂. Based on the panel data of 19 industries in 30 provinces, we established econometric model to analyze the relationship between income gaps of industries and economic growth. We found that they were negatively correlated and this relationship is reciprocal causation.
