为测量各地区的价格水平差异,本文探索性地利用我国31个省(市、区)的商品和服务价格数据。提出用EKS法、MST法和GK法来编制各地区居民消费价格空间指数并且首次提出选取参照地区的方法。研究发现:EKS法和GK法编制的空间指数具有稳定性和内在一致性;东部沿海和西藏地区的综合价格水平最高,而青海和江西省最低;中部地区和东北三省这两个集群内各地区间价格水平差异很小;4个直辖市中北京的综合价格水平最低,上海最高。
In order to measure the differences in price levels in different regions, this paper explores the price of goods and services in 31 provinces (cities and districts) in our country. EKS method, MST method and GK method are proposed to compile the spatial index of consumer prices in various regions and the first time to put forward the method of selecting reference regions. It is found that the spatial indices compiled by EKS and GK methods have the stability and inherent consistency. The prices of the comprehensive prices in the eastern coastal areas and in Tibet are the highest, while those in Qinghai and Jiangxi provinces are the lowest. In the central regions and the three northeastern provinces, The difference in price level is very small; the comprehensive price level of the four municipalities in Beijing is the lowest, the highest in Shanghai.
