基尼系数是经常被用来测试地区间收入水平差异程度的重要统计指标之一,但人们使用相同的指标,却得出了不同的结论。为了澄清基尼系数在衡量区际收入不均等程度的应用上存在的误解,有必要对此进行深入的讨论。 一、基尼系数在测度区际收入水平不均等程度中的应用 基尼系数是衡量一个总体收入分配状况或对社会财富的占有状况的经济指标,是根据洛伦茨曲线与有关线段所围成的图形的面积计算的。
The Gini coefficient is one of the most important statistical indicators that is often used to test the level of income differentials across regions, but people come to different conclusions using the same indicators. In order to clarify the misunderstanding of the application of Gini coefficient to measure the degree of regional income inequality, it is necessary to conduct an in-depth discussion. First, the Gini coefficient in measuring the level of inequality in inter-regional income Gini coefficient is a measure of the overall state of income distribution or the social status of the wealth of economic indicators, based on the Lorenz curve and the line segment surrounded by graphics The area is calculated.
