The purpose of this study is examining the persistence features of bilateral real exchange rates, Japanese yen and US dollar, of the newly industrial countries in Asia Pacific Rim, We employ numerous alternative econometric methods under different testing conditions to analyze the stationary problems for understanding the basic persistence characterizations, Furthermore, we also investigate the dynamic paths of real exchange rates after unit innovation for estimating their half-lives, The basic relationships between the prices and half-lives of real exchange rates are illustrated in the study. In general, the half-life is about 4.2 years in these countries, similar to the results in developed countries, In particular, the real exchange rate persistence in Taiwan is lightly lower than that in S. Korea,
