The COVID19 pandemic has caused great impact on China’s consumer industry, but it has also accelerated the process of digital transformation. Taking the catering industry as an example, based on the data of 16508 catering stores in Caimomo SaaS cloud catering management system from December 8, 2019 to July 31, 2020, this paper analyzes the epidemic’s impact on the catering industry in stages with the descriptive statistical methods. Meanwhile, VAR (Vector Autoregression) method was used to empirically test the impact of epidemic on catering industry and the interaction between takeout business and catering industry during the epidemic period. The results show that the impact of the epidemic on the catering industry is phased and heterogeneous, and the catering individuals with longer operation time have stronger antirisk ability. During the COVID19 pandemic, the online catering service represented by takeout business played a powerful supplement to the catering industry, and it still performed strongly in the post epidemic period. The catering industry should seize the opportunity of the epidemic situation to expand the takeout market. The catering individuals should enhance the antirisk ability and prepare well for the sudden risk.
