摘要
不同国家之间进行经济对比时通常用两种方法,一种是汇率转换法(简称汇率法),另一种是购买力平价法(PPP)。本文在前人研究的基础上,从横向和纵向比较了两种方法的差异,总结了一些变化规律,阐述了二者的优缺点。同时对两种方法在能源消费强度和人均能源消费量中的应用进行了比较,并对这两种方法产生差异的原因进行了讨论,认为购买力平价法更适合应用于资源经济领域的研究。
Two methods are usually used to compare the economy between different countries.One is the Exchange Rate Conversion Method（Exchange Rate Method for short）,and the other is the Purchasing Power Parity Method（PPP）.Based on previous studies,this paper compared the two methods from horizontal and vertical aspects,summarized several variations,and then discussed the causes of the differences between the two methods.At the same time,the two methods were compared with each other in their application to the energy consumption intensity and energy consumption per capita.This paper also discussed the causes of the differences between the two methods.It is held that the PPP method is more appropriate for the study of the resource economics.
