关于计量居民收入差距的方法有许多.根据黑龙江省及国家2002到2014年的城镇居民人均收入分组数据,分别用基尼系数、洛仑兹曲线法、变异系数法、泰尔指数法及极差系数法计算出居民收入差距的量化指标,实际论证了这些方法一致性与有效性.通常以基尼系数法为核心,以其它计量方法为辅助性工具,去判断、分析局部、整体之间的差异程度.
There are many ways to measure the income gap among residents.According to the per capita income group data of urban residents in Heilongjiang Province and the country from 2002 to 2014, we use the Gini coefficient, the Lorenz curve method, the coefficient of variation method, the Theil index method and the coefficient of difference Method to calculate the quantitative indicators of the income gap between residents, the actual demonstration of the consistency and effectiveness of these methods are usually Gini coefficient method as the core, other measurement methods as a supporting tool to determine, analyze the degree of differences between the local and overall .
