一类与洛伦兹曲线相关的不平等测度指数

Inequality Measurement Indices Associated With Lorentz Curve

文章对一类与洛伦茨曲线相关的不平等测度指数进行了较为系统的回顾与探讨,这些指数既包括基尼系数和Schutz指数等传统的不平等测度指数,也包括Bonferroni指数、De Vergottni指数和Zenga指数等国际上应用广泛但国内少见的不平等指数,并揭示了这些指数间的相互关联,总结了这些指数所满足的性质特征。

This paper reviews and discusses a class of inequality indices related to the Lorenz curve. These indices include the traditional inequality indices such as Gini Coefficient and Schutz index, and other indices widely used in the world but rarely used in China such as Bonferroni index, De Vergottni index and Zenga index. The paper also reveals the association between these indices, and summarizes the property characteristics of these indices.
