摘要
本文采用购买力平价的思想,探讨编制地区间价格指数的方法,进行我国内部地区间的价格水平比较,并且利用地区间价格指数将名义收入转换为实际收入,重新测算基尼系数。地区间价格指数显示,我国的地区间价格水平差异大,可贸易商品地区间价格差异相对较小,不可贸易商品地区间价格差异相对较大;各地价格水平与居民名义收入水平呈正相关关系,因此,各地居民实际收入差距小于名义收入差距,以居民实际收入测算的基尼系数较小。
This paper combines the PPP theory and the calculation of Gini Index in order to evaluate the income inequality more exactly. We discuss the methods to generate a cross-section price index. Using the index we can transform the nominal income into real income in PPP sense, and so calculate a revised real gini index. The cross-section price index indicates obvious difference among the prices of different areas, and further more a positive correlation of price and nominal income across different areas. Compared with the price difference of tradable commodities, the price difference of nontradable commodities is more significant.
