In recent years attention has been drawn to several shortcomings of the Concentration Index, a frequently used indicator of the socioeconomic inequality of health. Some modifications have been suggested, but these are only partial remedies. This paper proposes a corrected version of the Concentration Index which is superior to the original Concentration Index and its variants, in the sense that it is a rank-dependent indicator which satisfies four key requirements (transfer, level independence, cardinal invariance, and mirror). The paper also shows how the corrected Concentration Index can be decomposed and generalized.
近年来，人们已注意到集中指数的几个缺点，该指数是衡量健康状况社会经济不平等常用的指标。有人提出了一些改进方法，但这些只是部分补救措施。本文提出了集中指数的一个修正版本，它优于原始的集中指数及其变体，因为它是一个基于排序的指标，满足四个关键要求（转移、水平独立性、基数不变性和镜像性）。本文还展示了如何对修正后的集中指数进行分解和推广。
