Since the outbreak of the new crown epidemic, it has dealt a severe blow to economies around the world. How to quickly recover the traumatized economies in the post-epidemic era is now an important task. This paper constructs a prediction model based on the data of five major epidemics similar to the current one that occurred in history. Based on the prediction model built, we make a comprehensive forecast and individual economic indicators forecast for China's economy after the current epidemic, and the forecast results show that the overall economy of the country name and import and export can basically recover to the pre-epidemic level in about one year, and the recovery time for tourism and air transportation is longer and requires a slow recovery. This result is also very much in line with China's reality. China has already gained some experience in this kind of economic recovery, and a summary of these experiences will provide inspiration to other economies.
