摘要
主要考察不平等度量中广泛使用的统计方法,通过对几种常见统计度量方法的优缺点及其关系的分析,我们发现统计度量方法本身也存在着一些不如人意的地方,改进的办法之一就是使用公理化的度量方法和福利的度量方法。
This paper mainly analyses the statistical method which is widely used to measure inequality. Through discussing good and bad points of several common statistical measures and examining the relationship between such measures, we discover that the statistical method itself also has some unsatisfactory places, one of improvement means is to use the axiomatic method and the welfare method.
