Abstract:Taking a closed-loop supply chain composed of manufacturers and retailers as the research object, the impact of different environmental and social responsibility modes on system decision-making was explored. The results show that supply chain members who do not bear environmental and social responsibility can benefit from the environmental and social responsibility behaviors of other members of the supply chain. The environmental and social responsibility behaviors of any supply chain member can effectively improve the environmental and social governance performance of the system and improve the reliability of products. The environmental and social responsibility behaviors of supply chain members will have a profit effect, which can effectively adjust the profit distribution of the system.
