农村居民收入区域差异的走势和影响因素的实证分析——以江苏省为例

Tendency and Determinants of Income Gap of Rural Residents of Jiangsu Province

使用统计数据,对江苏省农村居民收入区域差异的走势作出判断,对其影响因素进行实证分析。结论是:江苏省13个市农村居民区域收入基尼系数的变动趋势在数学意义上并没有表现出威廉姆森倒U型曲线特征,说明农村居民收入区域差异并不必然随着收入水平的上升而无条件下降;研究表明非农就业、公路密度的增加可以使农村居民区域收入差异变大,农业支出、教育支出、资本密集度的增加使农村居民区域收入差异变小。
