| 摘 要： | 本文尝试在程永宏(2006)的基尼系数城乡分解方法基础上,论证一种适合多亚组的基尼系数组群分解新方法。主要内容是:第一,分析了现有分解方法不完善的原因;第二,推导出不含交叠项的多亚组情形下的分解方法,摆脱了交叠项的困扰;第三,提出一个组间不平等新指标并论证其理论依据;第四,明确解释了分解式和组间不平等新指标的社会福利含义。 |
| 关 键 词： | 基尼系数组群分解 组间不平等 社会福利损失 |

| Abstract: | This paper demonstrates a new decomposition of the Gini-coefficient under multi-subgroups.The main contents are as follows.First,the fundamental reasons of imperfections on present decomposition methods are analyzed.Second,a new decomposition of Gini-coefficient under multi-subgroup without overlap term is proposed.Third,the reliable theoretical basis and the clear economic significance of the between-group inequality index are proposed and proved.Lastly,the meaning of welfare economics behind the decomposi... |
| Keywords: | Gini-coefficient Between-group Measure of Inequality Welfare Losses |
