Based on the data of 1983 Q1 ~2008 Q1 of China and the estimation of sub -samples for the structural transformation point of multi-structures, the paper compares and contrasts the inflation rate, actual interest rate and nomi- nal interest rate, and finally estimates the consequences with reference to Bai and Perron’s (1998) sub -samples for the structural transformation point of multi-structures as well as the UDmax, WDmax and SupSupFT(l+1∣l) testing methods. The analysis shows that there is no evident Fisher Effect in China’s economy.
