The outdoor sports industry plays an essential leading role in developing the sports industry. Based on the essential characteristics and current development status of the outdoor sports industry in Changsha, the impact of COVID-19 on the demand and supply of the outdoor sports industry was studied. It is concluded that the demand side of the outdoor sports industry is affected by weather factors, high risks, competitive products generated by the progress of new technologies, epidemic prevention policies and related policies supporting outdoor sports development, and the transformation of people's pursuit of nature. On the supply side, it is mainly affected by the workforce shortage and innovative talents, limited site development, inadequate material supply, weakened entrepreneurial enthusiasm, and government policy support for entrepreneurship and small and medium-sized enterprises. In the face of hazards and opportunities, we should focus on improving the management and service level of outdoor sports enterprises, giving play to the function and role of sports social organizations, scientifically deploying major outdoor sports activities and event preparation, and enterprises to carry out self-rescue, and strengthening the long-term tracking research on the development of outdoor sports enterprises after the epidemic.
