國際上非基準(zhǔn)年購買力平價推算方法評價

摘要： 全球國際比較項目大約每隔5年或6年調(diào)查一次,有關(guān)國際組織應(yīng)用總量外推法、分類項目外推法、基期滾動法和簡縮信息法等方法推算非基準(zhǔn)年的PPP數(shù)據(jù),以便取得完整的連續(xù)時間序列。本文對國際上常用的各種非基準(zhǔn)年P(guān)PP推算方法和結(jié)果作詳細(xì)分析、評價。
The International Comparison Program(ICP) around the world is implemented about once every 5 or 6 years as survey benchmark.In order to obtain complete time series of PPP data,the international organizations use many methods to estimate the non-benchmark PPP,such as the method of global extrapolation,the method extrapolated by GDP main aggregates,rolling benchmark approach and reduced information approach.This paper reviews these estimate methods and results in details.
