| 摘 要： | 基于城镇居民人均可支配收入分组数据,运用非参数Kernel密度估计方法和MonteCarlo模拟技术,估计了1987—2008城镇居民收入分布及其演进特征。结果发现:(1)从全国城镇居民收入分布演进特征看,城镇居民收入不平等呈扩大趋势,基尼系数由0.17上升到0.33,增长近一倍,但没有观察到普遍和持久的两极分化现象(双峰分布);(2)在12个代表性省(区、直辖市)中,以经济发展模式(经济增长—收入分配)分类,广东属于平等发达型,湖南、四川、宁夏和广西属于不平等落后型,急需调整和转变增长方式;(3)从区域经济发展特征看,东部地区和东北地区收入增长较快,但收入不平等现象十分严重,中部地区和西部地区收入增长相对较慢,不平等现象相对轻微。

| Abstract: | This paper estimates the characteristics of urban residents′ income distribution from 1987 to 2008 by using grouped data and the Kernel density function.The results show: First,the whole urban residents′ income inequality presents expansile trend,but has no polarization phenomenon;Second,from 12 representative provinces,Guangdong is a equality-developed economy,Hunan,Sichuan,Ningxia and Guangxi are inequality-underdevelopment economy;Third,from the angel of district development,the east and northeast income increase rapidly,but the income inequality is serious.The central and west income increase slowly,but the income inequality is not serious. |
