In view of the risk of electricity price fluctuation in power enterprises under typhoon weather, a single risk management method is insufficient.

A sample of 943 manufacturing corporations listed on the Chinese stock market was selected. The financial data from 2008 to 2022 was sourced from the CSMAR database.
