【摘要】：基尼系数的局限性通常表现为:有时不能有效区别属性不同与分布差异;在没有给出洛伦茨曲线的情况下,慎用基尼系数的单纯比较分析。在常用统计分析工具以外可以借助贡献度和贡献率以及分配差异倍率等简单指标来提高基尼系数计算结果分析的科学性和准确性。首先,判断收入分配平等程度,尤其是在基尼系数相同的情况下,通过勾画洛伦茨曲线来揭示内部的差异特征的同时,运用对收入构成要素进行分解,求得贡献度和贡献率来判别收入分配中的内部差异特征。其次,利用收入各分组人数百分比,在已知基尼系数的前提下,简单直观地判断社会整体的收入差距程度。
[Abstract]:The limitation of Gene's coefficient is usually expressed as: sometimes it can't effectively distinguish the difference of attribute and distribution. When there is no Lorenz curve, we should use the simple comparative analysis of Gene's coefficient carefully. Besides the usual statistical analysis tools, we can improve the scientificity and accuracy of the calculation of Gene coefficient by means of simple indexes such as contribution and contribution rate, and the rate of distribution difference. First of all, the equal degree distribution of judgment income, especially in the case of the Gini coefficient is same, to reveal the differences of internal features by sketching the Lorenz curve at the same time, using the decomposition of income elements, the contribution and contribution rate to determine the internal differences in income distribution characteristics. Secondly, using the percentage of the number of income groups, the income gap of the whole society is judged simply and intuitively on the premise of the known Gene coefficient.

【正文快照】： 基尼系数和洛伦茨曲线是考察诸如收入分配等经济平等程度时经常使用的分析工具,基尼系数为数字指标、洛伦茨曲线则是用图示来解释其差异程度。虽然基尼系数的应用非常普遍,但是,在对基尼系数的认识上,尤其是对它的局限性认识上还存在较多误区。因此,为了加深对基尼系数的理解
