Research on Coordination of Green Supply Chain Based on Blockchain Concept

Based on the concept of blockchain and Stackelberg game theory, the coordination problem of green supply chain under random environment is studied. Firstly, based on the concept of blockchain, green supply chain decision-making models composed of a manufacturer and a single retailer were constructed, in centralized, decentralized, revenue-sharing and green manufacturing cost sharing contract situations. Secondly, models were solved. Finally, the relevant conclusions are verified through simulation analysis and comparison. The study found that the revenue sharing ratio, green manufacturing cost sharing ratio and repurchase coefficient have a significant combined effect on supply chain coordination. When the green supply chain is coordinated, the overall revenue of manufacturers, retailers, and the supply chain under the blockchain concept is higher than that under the non-blockchain concept. Simultaneously, it improves product greenness, retailer’s ordering and the supply chain robustness.
