Abstract: With the prosperous development of power generation of renewable energy source in China, traditional power generation industry suffers tremendous shock and it leads to the rapid increase of the uncertainty of the industry development. Firstly, to forecast the industrial trend at the power production side, by virtue of prosperity analysis method and starting from the viewing angle at power production side, relevant indicators impacting power production and development were scientifically chosen. Secondly, the prosperity indices of nation-wide power production were scheduled to conduct the empirical research on the prosperity fluctuation of China’s power generation industry in recent years. Research results show that the period of prosperity fluctuation is about two years approximately and the prosperity of China’s power production is on the rise in 2020 and will slightly fall in 2021. Thus, the growth rate of installed capacity of power source should be remained in control and the implementation of optimized configuration among different power source structures should be speeded up
