摘要:

通过把基尼系数的变化分解为收入增长效应和家庭排序变化效应、居民按城乡分组、居民家庭收入按来源构成进行分解,构建了基尼系数变化的三层分解模型。在此模型的基础上,采用2006~2011年中国健康调查数据(CHNS)讨论了各项收入增长对城镇、农村、城乡间及整体收入不平等的影响,并给出了一些政策建议。

关键词: 收入增长, 收入不平等, 基尼系数, 分解

Abstract:

It constructs the three layer decomposition model of Gini coefficient, which refers to decomposing the Gini coefficient into the effect of income growth and the change of family order, dividing the residents into urban and rural groups, and decomposing the revenue according to its sources. On the basis of the model, it discusses the impact of the income growth on the income inequality between urban and rural by using the Chinese health and nutrition survey data (CHNS), and puts forward some suggestions.

Key words: Income Growth, Income Inequality , Gini Coefficient , Decomposition.
