Optimization strategy of cooperation and emission reduction in supply chain under carbon tax policy

This paper considers a two-echelon supply chain system of cooperative emission reduction model consisting of one manufacture and one retailer under carbon tax policy. This paper analyzes the game model of total cooperation, completely uncooperative and emission reduction cost sharing, the results show that the cost-sharing factor of carbon emission reduction affects the emission reduction level in three kinds of games, and the cost-sharing factor of carbon emission reduction also affects the profits under completely uncooperative and emission reduction cost sharing model, there is a double side-effect effect in the decision-making model of total non-cooperation and emission reduction cost sharing model. We also proposal a coordination contract of Nash negotiated wholesale price contracts that can improve profits of both sides and realize the perfect coordination of both sides, finally we validate the effectiveness and environmental of the contracts through numerical examples.
