On the 28th, at the first China International Supply Chain Promotion Expo, various sectors engaged in heated discussions around the word "chain", including "building a modern agricultural industry chain, shortening the distance from the field to the tip of the tongue", "making a cotton plant to the extreme, creating a brand with one" chain "," achieving efficient and high-quality production with an efficient and stable supply chain ". Economic development is interconnected, and the industrial and supply chains are important support points. How to "add" a circle of friends for collaborative development and reduce the risks of supply chain management? Exhibitors and experts provide their own answers to these "computational problems" on the chain. Offline a car in less than 40 seconds - Tesla Vice President Tao Lin uses this data to illustrate the manufacturing efficiency of Tesla's Shanghai super factory. "The Shanghai factory achieved product delivery in the year of construction, and produced over 2 million electric vehicles in just over three years." Tao Lin believes that this speed stems from the deep integration with the Chinese supply chain. To build a car, we need to collaborate on a "chain". At present, the localization rate of Tesla's Shanghai super factory components exceeds 95%, with over 400 local first tier suppliers. It is the linkage of the supply chain that supports the rapid linkage between research and development and production. "Close cooperation with suppliers throughout the entire process is an important prerequisite for good manufacturing," said Tao Lin. Let the "circle of friends" continue to expand and the supply chain become increasingly collaborative. On the 28th, China General Technology Group and GE Healthcare signed a contract at the Chain Expo to deepen cooperation in the field of medical imaging digitization, focusing on smart healthcare to launch more accurate and personalized health solutions. In the view of Lu Yimin, General Manager of China General Technology Group, promoting collaborative development through chain thinking is the key to building a comprehensive and full lifecycle big health industry chain. From increasing overseas layout to investing and cooperating with companies such as Ledun Pharmaceuticals to introduce technologies such as cell culture media, Huaxi Biotechnology is continuously accelerating its integration into the global biological manufacturing supply chain industry chain. "We will leverage the Chain Expo to strengthen our close connection with world-class enterprises and more partners, and embrace broader markets and development opportunities," said Gao Yi, Deputy General Manager of Huaxi Biotechnology. Gathering chains into clusters, clustering into momentum. Accelerate the development of industrial clusters and better leverage the additive role of industrial and supply chain collaboration. This is a reflection of the development of Wuhan Optics Valley Optoelectronics Information Industry Cluster: through mutual cooperation between upstream and downstream, large, medium and small enterprises work together to facilitate efficient division of labor, forming effective supply chain circulation within the cluster. The core supporting facilities of leading enterprises can be basically solved nearby. The optical communication full industry chain supporting consortium created has driven the development of more than 100 upstream and downstream enterprises, with an industrial scale exceeding 100 billion yuan. Key enterprises in Changchun Automobile Economic and Technological Development Zone presented more than 40 exhibits in the upstream and midstream of the automobile supply chain in the exhibition area. Chongqing organized a group to participate in the Chain Expo, from the supply chain activities of the Beijing Tianjin Hebei industrial chain to the promotion of key industries in Shenzhen. The series of industrial cluster activities at the Chain Expo also demonstrated the practice of developing characteristic industries based on endowments and adapting to local conditions in various regions, and the coordinated development of multiple clusters participating in exhibitions. Reduce enterprise operating costs and risks with a stable supply chain. From high-purity crystalline silicon to solar cells and photovoltaic power stations, Tongwei Group has laid out its layout in the photovoltaic field and also focuses on various aspects
