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，继续重点收集了336个样本地市2000～2009年共10年的数据，改变统计指标和样本范围，再次运用非参数Kendall下相关性检验方法进行实证分析。金融深度不分组检验得到多数不显著的正相关或者负相关，金融深度分组检验没有得到显著的整体“倒U关系”，或者是“U关系”；在细节上得到局部的“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，在理论与实证研究中需要深入探索其中的复杂性。By analyzing the relationship between regional financial development and the change of urban-rural in- come distribution inequality, based on the forthgoers＇ works 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 336 sample prefecture cities＇ data from 2000 to 2009, and by changing statistical indicators and sample range, the paper uses method of non-parametric examination of kendall τ rank sum. From sample prefecture cities＇ data the paper finds positive or negative correlation in ungrouped test which are most not statistically significant, and doesn＇ t find that there is any statistical significant inverted U or U relationship on the whole in grouped test ; 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 and the sample data and inspection methodology are not just coincide, further re- search should be done to explore the complexity of them.
