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。文章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。Purchasing power parity is a fundamental concept in exchange rate deciding theories. However, misalignments from PPP are often found because real exchange rate is apt to be influenced by so many short-term or long-term economic factors. This thesis makes a synthesized analysis over models on real exchange rate misalignment from PPP, and concludes that the fundamental factors such as productivity, government expenditure, money supply, preferable demand and pricing strategy, all have a serious impact on real exchange rate.
