Promoting the development of grain logistics in the new era plays an important leading and supporting role in ensuring national grain security and accelerating the high-quality development of the grain industry. Grain logistics connects grain production, circulation and consumption, which is an important guarantee for maintaining the security and stability of the grain industry chain and supply chain and serving the new development pattern of double circulation. This research strives to break through the bottleneck of large overall scale, low degree of intensification, long transportation distance between production and marketing areas, difficulty to match grain supply and demand, low degree of specialization of grain logistics, and unbalanced regional development, on the basis of the improvement of channels, line layout and logistics level in the "Thirteenth Five-Year Plan" period under the new situation and new requirements. We also strive to solve the key problems of layout optimization, interconnection, and facility improvement of grain logistics from perspectives of improving system level, promoting balanced development of regions, and improving professional service capability. We suggest to apply new technologies, adopt new models, make up for shortcomings, and reduce costs to build a modern grain logistics system with reasonable layout, complete functions, wisdom and efficiency, open sharing, and green ecology. This research provides a reference for the high-quality development of grain logistics in China in the new era.
