摘要
针对区域金融发展与城乡收入分配差异变化的关系问题,在前人基于2007年县市横截面数据实证研究得到"倒U关系"的基础上,继续收集1912个样本县市2005、2007、2009年共三年的数据,改变统计指标和样本范围,再次运用非参数Kendallτ相关性检验方法进行实证分析,不分组检验都得到正相关,分组检验没有得到显著的整体"倒U关系",反而是"U关系",但是得到局部的"倒U关系"和"U关系",有一些是统计显著的,而另一些不是统计显著的。这说明经济理论、样本数据、检验方法并不是恰好吻合的,需要深入探索其中的复杂性。
For analyzing the relationship between regional financial development and the change of urban-rural income distribution inequality, based on the forthgoers' work which have used Chinese county-level cross-section data in 2007 to an empirical research and have found an inverted U relationship, this paper does a further work, which based on Chinese county-level cross-section data in 2005 and 2007 and 2009, and by changing statistical indicators and sample range, using method of non-parametric examination of kendall -c rank sum. The research finds completely positive statistically significant correlation in ungrouped test, and dosen't find that there is an inverted U relationship on the whole in grouped test, conversely there is an statistical significant U relationship, in the details there are partially inverted U or U relationship, some of which are statistically significant and others not. This shows that economic theory, the sample data, and inspection methodology is not just coincide, further research should be done to explore into the complexity.
