摘要
2011 年两会关注的热点再次集中在收入分配改革问题上,国家领导再次提出工
作部署,要求加大收入分配改革力度。无疑,2011年是“十二五”规划的开局之年,
同时也是加快经济发展方式转型的重要时机。改革开放以来,我国经济一直以接近
两位数的的增速增长,与此同时,各种因素在不断的加大收入差距。由此来看,缩
小居民收入差距是一个迫切问题。
基尼系数是国际上综合考察居民收入分配差距的主要指标,历来受到重视,对
衡量收入差距有着无可替代的重要地位。但由于我国数据方面存在的特殊性,使得
基尼系数的计算没有统一的标准。
本文的整体思路是:首先对基尼系数及混合基尼系数的相关理论进行研究分
析,并加以梳理总结。其次对城乡分组数据进行处理从而将其整理为统一的城乡数
据,运用广义逻辑斯蒂函数进行拟合,计算出我国 20 个地区 1996 年~2008 年的农
村基尼系数、城镇基尼系数和混合基尼系数。最后,利用非参数估计中的核密度估
计法对三种数值进行趋势分析,得出三种基尼系数不断扩大的结论。

Abstract
The government working meeting concerned again concentration in e distribution
reform issue in puts forward the work deployment,demand increased
e distribution reform. The year of 2011 is the twelfth of 5 years of planning to start
the year, but also accelerate the transformation of the mode of economic development
important opportunity. Since the reform and opening up, the economy of china has been
close to double-digit growth, meanwhile, various factors in the unceasing increase the
e gap. In this respect, narrowing the e gap of residents is a pressing problem.
Gini coefficient is the prehensive investigation residents e
distribution gap between the main index, has been seriously, to measure e gap has
irreplaceable status. But because of the data of China existing particularity, so this makes
Gini coefficient calculation no unified standard.
In this paper, the author of the whole Gini coefficient and mixed Gini coefficient of the
relevant theory of research and analysis, and performs b summary. Secondly, to
urban and rural packet data processing and arranged them for unified urban-rural data,
applying generalized logistic function fitting, calculated our 20 regions in 1996~2008
rural Gini coefficient, town Gini coefficient and mixed Gini coefficient. Finally, using
