一、浙江省各地区收入分配差距的状况(一)城镇居民内部的地区差距及变化研究城镇居民人均可支配收入地区间差距的常用指标是基尼系数。但是由于很难获得历年完整的基尼系数数据,本文采用相对差异系数来衡量地区间的差距。相对差异系数(V)是相对于平均差和标准差更能准确测量相对收入差距的工具,其计算公式为V=S／Y,其中S2=(∑(Yi-Y)2)／N。本文收集了1995-2005年浙江省11个地区的城镇居民人均可支配收入数据,根据当年价格计算出它们的V值(见表1),并做出1995-2005年城镇居
I. The Income Distribution Disparities in Zhejiang Province (I) Regional Disparities and Changes in Urban Residents The commonly used indicator of the regional discrepancies in per capita disposable income of urban residents is the Gini coefficient. However, since it is difficult to obtain the complete Gini coefficient data over the years, this paper uses the relative difference coefficient to measure the regional disparity. The relative difference coefficient (V) is a tool that can accurately measure the relative income gap relative to the average difference and the standard deviation. The calculation formula is V = S / Y, where S2 = (Σ (Yi-Y) 2) / N. This paper collects per capita disposable income data of urban residents in 11 regions of Zhejiang Province from 1995 to 2005, calculates their V values based on the current prices (see Table 1), and makes a survey of urban residences from 1995 to 2005
