| 摘 要： | 购买力平价说是一种基本的汇率决定理论,但影响购买力平价关系成立的短期或长期经济因素众多,从而使得实际汇率经常偏离平价关系.本文对有关文献中各种购买力平价偏离模型进行了综合分析,阐明了生产率、政府支出、货币供给、偏好需求和定价策略等基本因素作用于实际汇率的经济机制.

| 关 键 词： | 购买力平价偏离 汇率超调模型 扩展的Mundell-Fleming模型 结构模型 |

| Abstract: | Purchasing power parity(PPP) is a basic exchange rate determinant theory.However,due to the numerous short and long term factors that affect PPP,the real exchange rates frequently deviate from it.This article surveys the various models of PPP deviations and expounds the impacts of productivity,government spending,money supply,preference demand and pricing on the real exchange rates. |
