Abstract: In view of the problem that the traditional co-frequency power prosperity index lacks timeliness and dynamism, a MF-MS-SW model is constructed, which can analyze both the quarterly and monthly frequencies at the same time. Leading, consistent and lagging mixed-frequency sample data consisting of 21 economic indicators are selected to construct China's mixed-frequency power prosperity index and early warning signal system. The results show that the proposed MF-MS-SW measurement model has a good description of the fluctuation characteristics of China’s power prosperity index, i.e., multiple-frequency and nonlinear characteristics, and has a high degree of consistency with China’s overall economic development status. The model can be used for early warning and forecasting. It is recommended that the energy and power sectors regularly compile and publish China's power prosperity index, reflecting the real-time changes in the power industry's economic status and promoting the optimization and adjustment of energy structure.
