Abstract: The global outbreak of the COVID-19 pneumonia epidemic in 2020 has had a huge impact on the high-quality development of private economy in China. Based on the data of the questionnaire survey on the COVID-19 pneumonia epidemic, this paper finds that the epidemic will expose small and medium-sized private manufacturing enterprises to unprecedented survival pressure. By comparing the development path of the private manufacturing industry after the SARS in 2003, this paper makes a pre-judgment on the development of the private enterprises after the COVID-19 pneumonia epidemic:As the COVID-19 pneumonia epidemic is gradually brought under control, the macroeconomic crux is changing from large impact on both supply and demand to insufficient aggregate demand, which will inhibit the recovery of the manufacturing industry. The highly uncertain external environment may further expand the negative impact of the epidemic on manufacturing companies through trade channels. Regarding the high-quality development of the private economy after the COVID-19 pneumonia epidemic, this paper puts forwards the following policy recommendations:(1) Improving the national health and public safety system, and the ability to respond to major public health emergencies. (2) Promoting high-quality development of private economy by adjusting stock economic structure and optimizing incremental economic layout. (3) Supporting and guiding private enterprises to turn crises into opportunities and fully integrate them into the construction of complete industrial system. (4) Increasing the targeted support to small and medium-sized enterprises, and improving the assessment mechanism for small and medium-sized enterprises. (5) Using insurance to resolve risks, and encouraging insurance institutions to participate more risk management and corporate governance of private enterprise.
