Abstract: In order to study the coordination problem in the closed-loop supply chain with third-party structure under the government multi-policy situation and based on multi-policy and retailer dominance, three cases of supply chain models are established, and the optimal pricing decisions and profits in the supply chain under different conditions compared and analyzed. The results show that the government can effectively increase the amount of recycling and increase the profit of the third party and customer utility in the reverse supply chain, but decrease the profit of the retailers and manufacturers and customer utility in the forward supply chain; and that the efficiency loss is caused by decentralized decision. A profit and expense sharing contract and authorization-optimal recovery quantity contract are designed to improve the profit of supply chain members. By coordination, the profit of supply chain members and customer utility are improved.
