In the era of big data, the importance of information in economic activities has received more and more attention. How to effectively collect and analyze information and use the rules extracted from information to guide production practice has become a key factor for enterprises to improve their own competitiveness. Companies with a high degree of information sharing are often able to demonstrate higher levels of innovation and business. Information sharing refers to information exchange and sharing between different information departments, so as to achieve a more reasonable allocation of resources, save social costs, and create more wealth. It is an essential means to improve the utilization rate of information resources and avoid repeated waste in information collection, storage, and management. It is based on standardization and standardization of information and is guaranteed by law or statute. The efficiency of information sharing depends on the development of information system technology and the improvement of transmission technology.
However, with the extension and expansion of the production chain, the problem of Information Island in the supply chain is becoming more severe. Supply chain refers to a functional network structure that around the core enterprise, starts with supporting parts, makes intermediate products and final products, and finally delivers products to consumers through sales network, linking suppliers, manufacturers, distributors and end users into a whole. The management concept of supply chain management is to seek the overall optimization of the supply chain from the perspective of consumers through cooperation among enterprises. Successful supply chain management can coordinate and integrate all activities in the supply chain, and eventually become a seamless integration process. The supply chain is a system that includes suppliers, manufacturers, transporters, retailers and customers. Supply chain management refers to all kinds of activities and processes of planning, coordinating, operating, controlling and optimizing the whole supply chain system. Its goal is to deliver the right products needed by customers to the right place at the right time, according to the right quantity, quality, and status, so as to minimize the total cost. Obviously, supply chain management is a management mode embodying the idea of integration and coordination. It requires the members of the supply chain system to work together to cope with the complex and changeable situation of the external market. However, facing the complex and changeable market environment in the era of economic globalization, it is not easy to achieve efficient supply chain management. One of the important reasons is that there is not only a lot of information in the market every moment, which contains abundant opportunities but also indicates a lot of risks. However, enterprises in the supply chain often fail to grasp useful information timely and accurately, so they are baffled when making decisions and are difficult to make correct decisions. In other words, all member enterprises should share enough information to eliminate the uncertainty within the supply chain system. The way to solve this problem is to carry out informatization.
