Abstract: In recent years, e-commerce platforms have begun to empower supply chain members by virtue of their advantages in the field of digital intelligence, which has greatly affected the operational decisions and benefits of e-commerce supply chain members. For example, Alibaba released a data analysis system in 2018 called “Intelligent Supply Chain Brain”, using big data and algorithms to optimize supply chain decisions, and Nestle became the first brand to use this intelligent system. Nestle can check its order quantity, transportation time, inventory amount and turnover days through this system, and optimize its production, inventory and sales management based on this. After using this system, the inventory turnover of its Tmall official flagship store has dropped by 40%, and the efficiency of attracting new customers has increased by more than 98%. This phenomenon is reqarded as platform digital empowerment. According to the business practice and related literature description, platform digital empowerment is defined as the behavior that the platform relies on its massive operational data, with the help of emerging information technologies such as big data and cloud computing to gain insight into consumer characteristics and provide more accurate and intelligent data strategy support for supply chain partners. The platform digital empowerment helps to improve the supply chain partners' ability to apply data and improve their operational efficiency.
