摘要
本文为确定一个时期内总体收入分配或特定部分的收入分配究竟是否趋向两极分化和比较中间收入等级和高收入等级的分配份额提供了方法。用帕雷托分布拟合我国1988年和1995年两年的居民收入分配,发现1995年和1988年相比:(1)没有明显证据表明农村居民收入存在两极分化,城镇居民在排除了收入最低的10%人口后,有明显的两极分化趋向;(2)中间等级收入份额减少,收入向高收入者集中;(3)高收入者内部收入分配差别扩大;(4)社会成员在不同的收入等级之间的流动更加容易。
This paper provides a method for verifying whether the income distribution is polarized or not, and for measuring the share of meddle and high income classes within a particular part of a distribution. By fitting the Pareto distribution to the Chinese household income data, the paper finds that from 1988 to 1995, （a） incomes were not polarized among rural residents, and they were polarized among urban residents if 10% population of lowest income excluded; （b） either among rural or urban residents, the incomes were being aggregated to high income classes;（c） the inequality among the high income recipients went up; d） the mobility between the different income classes for recipients became easier.
