Abstract: The decision-making of remanufacturing closed-loop supply chain under controllable quality of recycled products is studied. Based on a remanufactured closed-loop supply chain consisting of a single manufacturer and a single seller, quality functions and reward functions are introduced. Based on this, a manufacturer-led Stackelberg game model under centralized and decentralized decisions is built. The optimal solution of the model under decision-making conditions, and the effects of the recovered quality on various parameters are analyzed using numerical simulation. Research shows that compared with decentralized decision-making, joint decision-making has higher economic returns and risk sensitivity. Whether it is decentralized decision or joint decision-making, the recovery price and supply chain company profits are positively related to the quality of recovery, and the "market promotion" effect is formed. Consumers' strong green preferences and recycling price preferences can have a positive impact on supply chain profits.
