Abstract
China's small and medium-sized enterprises have achieved rapid, healthy and sustainable development and contributed more and more to economic growth. However, the COVID-19 epidemic broke out in Wuhan in early 2020. The rapid spread of the epidemic brought serious threats to the health of the people of the whole country, forcing the government to take the measure of "closing the city" in Wuhan on January 23, encouraging citizens to go out less frequently and isolate at home, and various provinces and cities made first-class responses one after another. Due to the concentrated outbreak of global epidemic, China's economic development faces great uncertainty. In this regard, this paper analyzes the adverse effects of the epidemic from the perspective of SME management, and at the same time analyzes how SMEs can get out of the management dilemma and how to improve their ability to resist risks under the uncertainty of external environment in the post-epidemic era. In the post-epidemic era, in order to solve the immediate dilemma, small enterprises must improve their ability to resist risks and respond, and improve their competitiveness in the market by reducing production, transportation and operating costs.
