In order to explore the effect of channel power structure on the decisions and performance of manufacturer collecting closed-loop supply chain, the centralized decision-making supply chain and three decentralized supply chains with different channel power structure have been analyzed. The study found that decentralized supply chains are not coordinated, and the uncoordinated degree is associated with the channel power structure. The retail price in Stackelberg structure is higher than Bertrand structure, and it in Manufacturer- Stackelberg (MS) structure is higher than Retailer- Stackelberg (RS) structure. The recycling proportion in Stackelberg structure is lower than Bertrand structure, and it in MS structure is lower than RS structure. The system profit in Stackelberg structure is lower than Bertrand structure, and it in MS structure is lower than RS structure. For each member enterprise, his profit is highest in himself leadership Stackelberg structure, and lowest in the other’s leadership Stackelberg structure.
