摘　　要：本文介绍了自 2 0世纪 70年代以来开放经济理论的基石———购买力平价及实际汇率的相关实证检验方法。以发达国家双边汇率作为样本数据进行检验 ,发现在样本期间足够长、样本数量足够多的情况下 ,PPP假设成立。此外 ,由于实际汇率对PPP的均值复归呈现出显著的非线性特征 ,今后的研究方向应当是建立非线性汇率动态模型。The paper reviews the main empirical research on testing validity of PPP and real exchange rates developed by the economists since 1970s. Most of the results support the hold of PPP if applying long span data or panel data into the model testing the real exchange rate for major industrial countries. Since mean reversion in real exchange rates displays significant nonlinearities, future effort should lie in the generating of the nonlinear real exchange rate dynamics.
