巴拉萨-萨缪尔森效应假说：文献回顾与概念界定

摘要

Because there are actually diversified understandings on the definition of Balassa -Samuelson Effect , it is necessary to refer back two seminal articles respectively written by Sameulson and Balassa .Balassa-Samuelson Effect is a theory based on the disparity of productivity growth between tradable and non -tradable sectors to explain the general price gap among countries and the long -run trend of the real exchange rate .The kernel is that the productivity growth tends to tradable sector , and the wage level will be improved caused by the tradable productivity growth which will lead to an inflation of the non-tradable product cost therefore a rising of the whole price level .As a result, a richer country will have a relative higher price by a static comparison , and a faster growth country will have more appreciation of its real ex-change rate by a dynamic comparison .%由于学术界关于巴拉萨-萨缪尔森效应定义存在不同理解，有必要重新回顾Samuelson和Balassa的两篇重要文献。巴拉萨-萨缪尔森效应从部门生产率发展差距解释国际物价水平静态差距和实际汇率长期动态趋势原理，其核心观点认为，生产率是偏向贸易部门增长的，工资水平受贸易部门生产率增长的推动而上涨，导致非贸易品的成本上升从而价格上升。这种结果表现在国别静态比较上，越富的国家相对物价水平就越高；表现在一国动态发展上，高增长的国家实际汇率会升值。
