Analysis of regional power demand cycle is the foundation of researching the national power demand cycle. Firstly the growth rate data of power demand in China from 1994 to 2005 is dealt with the H-P filter, and the periodicity factors of the nation and provinces power demand are obtained. Secondly the periodicity factors of the provinces power demand are treated with cluster analysis, and the problem whether the regional power demand cycle exist in China is discussed. Subsequently through studying the question which provinces mainly affect the national power demand cycle, the problem that the regional power demand cycle influences the national power demand cycle is analyzed.
