Based on the characteristics of complexity, synergy, integrity and dynamics of agricultural products crosschannel circulation, this paper starts with the advantages of traceability, analyzability and sharability brought by digital technologies and modes, compares and analyzes the circulation links and influencing factors of agricultural products circulation forward supply chain and reverse supply chain, and investigates the optimization model construction of enterprise supply chain. Starting with the subject-platform of cross-channel integration of agricultural products circulation, this paper analyzes the influencing factors and paths of enterprises, and analyzes the mechanisms of competition and cooperation, safeguard and evolution of the platform using game theory and synergy theory. Starting from the method of cross-channel integration of agricultural products circulation-mode innovation, from the perspective of logistics,e-commerce, technology, etc., this paper puts forward the innovative implementation path of cross-channel integration of agricultural products circulation. The results of the project will be helpful to reduce the links and optimize the circulation paths of agricultural products; set production according to demand and promote the precise docking of agricultural production; promote structural symmetry between supply and demand, and reduce wastage and waste; achieve largescale operation, reduce costs, and make a wide range of profits. It would be of great theoretical value and practical significance to promote the transformation of agricultural products circulation from simple production type to production service type and to form a circulation system with high quality, safety and efficiency.
