The digital supply chain is a new type of supply chain based on a new generation of information technology and modern management concepts and methods such as the Internet, Internet of Things, big data, artificial intelligence. The components of the digital supply chain mainly include the current more emerging digital technologies, such as cloud computing, Internet of Things IoT and traditional ware technology, big data analysis, artificial intelligence, blockchain, etc., which creates good conditions for the traditional supply chain to realize the digital transformation of the real-time online supply chain form driven by customer demand, and it can obtain data in real time through multiple channels to realize the supply chain end-to-end visualization, and maximize the use of data to provide the basis for intelligent decision-making. The activities in the supply chain can be reflected as the activities of information flow, logistics and capital flow in the supply chain; on this basis, the issue of supply chain digitization can be split by two dimensions: dimension one is internal and external to the enterprise; dimension two is the extension of the same flow and different flows; and dimension two is the extension of the same flow and the extension of different flows. On this basis, the issue of supply chain digitization can be split into two dimensions: dimension one is internal and external to the enterprise; dimension two is the extension of the same "flow" and the interaction between different "flows". The core of supply chain digitization by each participant lies in two aspects - horizontal extension of the same value chain and vertical interaction between different value chains. 2021, the revenue of supply chain digitization services by different types of participants will be about RMB 2.8 trillion, and supply chain digitization services can be divided into two categories according to the digitization transformation of information, logistics and capital flows. and capital flow digitalization transformation is divided into three corresponding parts. In terms of structural share and growth, the logistics segment of supply chain digitization services has the highest share, but the supply chain digitization services of information flow and capital flow have strong growth.
