With the rise of the Internet age, the e-commerce mode in China's retail industry has achieved unprecedented development. E-commerce retail has begun to occupy the original share of the brick-and-mortar retail industry gradually. This trend is more significant in the field of beauty and skincare. Tmall, Taobao, JD.com and Tiktok, as the representative online retail channels, have become primary channels for many users to buy skin care and beauty products. Therefore, for the retail industry, online channels can expand sales productivity of products and scale up revenues greatly for enterprises. However, as the Internet enters inventory era and online traffic reaches its peak, the inefficient efforts in online channels may raise the marketing expenses, leading to a decline in their profit margins. This thesis investigates whether e-commerce transformation of traditional retail enterprises in China, e-commerce transformation of different types of retail enterprises, and e-commerce transformation of retail enterprises in different regions will have an impact on corporate performance through empirical analysis. Thus, we will investigate whether e-commerce transformation can significantly promote the growth of corporate performance from multiple perspectives and whether corporate performance can be significantly improved when spending more time on e-commerce transformation.This study employed factor analysis method, using four financial indicators in the aspects of profit-making capability, operating capability, growth ability and solvency. Listed companies in the retail industry in Shanghai and Shenzhen markets from the year of 2008 to the year of 2021 were selected as the research sample. Data were collected to define the transformation years. In terms of the financial data of Chinese listed companies in the retail industry for seven years before and after e-commerce model transformation, this thesis analyzed the changes in corporate performance of traditional Chinese listed companies in the retail industry after e-commerce transformation. The analysis of the empirical results shows that there is no significant improvement within one year after the e-commerce transformation of traditional retail enterprises, and there is a significant improvement in corporate performance after one year. At the same time, this thesis verifies that for the traditional retail industry, e-commerce transformation can promote corporate performance; with different retail enterprise backgrounds, retail enterprises with non-state-owned backgrounds are more able to improve corporate performance; in relatively developed regions, e-commerce transformation shows greater promotion effect on the performance of retail enterprises. / Business Administration/Finance
