In 2020，due to the expected decline in the number of inbound passengers and the per capita catering consumption，in addition，the local residents have less dining out during the epidemic period，and people tend to be cautious about the dining consumption due to the pressure on income，resulting in a significant drop in annual revenue of the catering industry. In order to reduce the impact of the epidemic on economy，the supply side and demand side of the catering market，and to avoid the medium and long-term impact，it is suggested that the government should implement positive fiscal policies，measures for stabilizing financial market，and formulate targeted policies for industrial assistance and revitalization during and after the epidemic，so as to preserve and develop the supply and demand capacity of the catering market. The epidemic situation has inevitably changed some consumer behaviors in the catering market. Consumers will pay more attention to the hygiene and health factors of the products and the tidiness and sanitation of the dining environment. The catering industry needs to summarize the experience of the epidemic containment，pay attention to the change of consumer behavior and conduct active cooperation. In addition，it is also necessary to strengthen the ability of online dialogue and communication with consumers and delivery of takeout.
