在国际经济比较时,较为恰当的货币转换因子是空间价格指数,它可以消除不同国家和地区经济总量中所内含的价格因素差异,使得经济比较和价格水平比较成为可能。本文基于空间价格指数,利用世界银行所公布的ICP2011数据,比较了2011年世界各国家和地区实际经济总量及国际地位,并进行主要支出项目以及人民实际生活水平和物价水平的国际比较。 In the comparison of the international economy, the more appropriate currency conversion factor is the space price index, which can eliminate the differences in price factors contained in the economic aggregates of different countries and regions, making it possible to compare economic comparison with price levels.
