本文探讨适合组数据的拓展基尼系数计算公式,给出了协方差、回归系数等算法,论证了拓展基尼系数满足的若干公理性质;纠正了现有拓展集中度指数计算中存在的问题,重新定义了拓展健康不平等测度和健康绩效指数;给出税收拓展累进性指数,并利用税收边际效应定义了一个新的税收累进性测度。同时使用以上方法,对我国各地区孕产妇保健的公平性、地方财政收入的税收累进性进行了实证分析。
本文探討適閤組數據的拓展基尼繫數計算公式,給齣瞭協方差、迴歸繫數等算法,論證瞭拓展基尼繫數滿足的若榦公理性質;糾正瞭現有拓展集中度指數計算中存在的問題,重新定義瞭拓展健康不平等測度和健康績效指數;給齣稅收拓展纍進性指數,併利用稅收邊際效應定義瞭一箇新的稅收纍進性測度。同時使用以上方法,對我國各地區孕產婦保健的公平性、地方財政收入的稅收纍進性進行瞭實證分析。

This Paper discusses computing extended Gini index for grouped data, promotes new methods of covariance and slope for Gini index, proves several characters of extended Gini index which satisfied with poverty axioms, corrects some mistakes about extended concentration index, redefines extended health equality index and health effective, gives several defines for tax progressive, and defines a new measurement of tax progressive with tax relative marginal effect. Applying above methods to maternal mortality rate and revenue of local government by region in China, empirical analysis of health equality and tax progressive are carried on.
