%X This paper proposed a method to get the optimal cluster number of FCM in real systems.Preset some reasonable cluster numbers,and then chose a cluster number as the optimal cluster number by some representative validity functions.Testing on the X30 and Bensaid data sets demonstrates the effectiveness and reliability of the proposed method.And finally gave an experiment on China's 31 regions according to the level of science and technology(S&T) progress.
