购买力平价(PPP)可为发行不同货币的国家间比较提供比汇率法更加可靠的数据基础,因此在国际经济比较领域的应用日益广泛。本文对现有的PPP测算方法按照指数法和随机法两大板块进行了综述,包括了传统的EKS法、最小间隔树法、链式法、星形法、平均价格法、原始CPD法、CPRD法等基本方法,以及此后发展的加权EKS法、特征CPD法、空间CPD法和加权CPD法,简要评述了这些方法的基本思想及各自的优缺点。随后,本文详尽总结了两大类方法的发展脉络,深入探讨了这些方法的适用性问题,并作了研究展望。
Abstract：Purchasing Power Parity(PPP) can provide more robust data for the comparison among countries which have different currencies and thus has been widely used in international comparison fields.This paper reviews the PPP Estimate Methods and divides them into two main branches.Both basic methods such as EKS、minimum span tree、chain method、star method、average price method、CPD、CPRD and later developed methods such as weighted EKS、characteristics CPD、spacial CPD and weighted CPD were reviewed.This paper expounds methods' principle ideas and their respective strengths and weaknesses,summaries their development paths,explores the applicability of these methods and makes the research prospects.
