摘要
文章主要对基尼系数的计算与分解方法进行了研究.首先,对基尼系数计算公式中的缺陷进行了讨论和分析,对未分组和分组计算公式进行了修正;然后,对基尼系数的子群公式进行了研究并证明了不同公式的等价性,给出了基尼系数新的上、下界;最后,计算了2013-2019年全国居民人均可支配收入基尼系数,结果表明使用修正后的公式计算出的基尼系数更加贴近真实的基尼系数.
Abstract
This paper mainly studies the calculation and decomposition methods of Gini coefficient.Firstly,the paper dis-cusses and analyzes the defects of the calculation formulae of Gini coefficient,and revises relevant ungrouped formulae and grouped formulae.Then,the subgroup formulas of Gini coefficient are studied and the equivalence of different formulas is proved.New upper and lower bounds of Gini coefficient are given.Finally,the Gini coefficient of per capita disposable income of national residents from 2013 to 2019 is calculated.The results show that the Gini coefficient calculated by the modified formula is closer to the real Gini coefficient.
