Abstract
In the report of the 19th National Congress of the Communist Party of China, General Secretary Xi clearly pointed out: "Chinese economy has shifted from a stage of high-speed growth to a stage of high-quality development", which indicates that China's economic development has entered a new era. However, the current new crown pneumonia epidemic continues to spread, which has had a continuous impaction on global economic development, and China has also entered a post-epidemic era. This article collects data from the second quarter of 2019 to the third quarter of 2020 to study the impaction of the epidemic on China’s economic development momentum and economic structure to analyze the high-quality development of China’s economy in the post-epidemic era, and propose countermeasures to promote the high-quality development of China's economy.
