COVID-19, which is classified by WHO as a global pandemic and has a significant impact on all of humanity, it has been affecting different countries around the world since 2019 in terms of economic, cultural, and social aspects for a long or short period, with a deep or shallow impact. China, which has made significant achievements in controlling the development of the epidemic, completely relaxed its epidemic prevention policies that had been in place since the end of 2022, including restrictions on travel. This paper aims to study the impact of COVID-19 on the change in consumer behavior in China. According to the analysis, it is concluded that offline shopping is still irreplaceable, but more and more people are choosing online shopping as a shopping method. In particular, COVID-19 has accelerated this shift in shopping behavior. These results provide many companies with development ideas on how to capture the changing shopping style of consumers and find solutions to meet their needs in today's fully developed Internet.
