Remanufacturing closed-loop supply chain can effectively deal with the deterioration of environmental resources and the limited supply of resources as a part of circular economy. Government subsidies are an important factor to promote its development. In this paper, we consider a two-stage remanufacturing closed-loop supply chain, where the retailer is responsible for recycling, and the manufacturer will innovate in remanufacturing technology based on the extended producer responsibility system. The study constructs a Stackelberg game model with the manufacturer as a leader, and compares the different impacts of the two subsidy strategies on supply chain decisions (i.e., subsidies for investment in remanufacturing technology innovation and subsidies for the cost of remanufactured products). Numerical analyses are conducted to visualize the effects of subsidies on the decision-making of closed-loop supply chain members, environmental benefits, and social welfare. The findings indicate that when the level of subsidy is low, government subsidies for investment in remanufacturing technology innovation can accelerate the upgrading of remanufacturing technology, leading to higher environmental benefits and social welfare compared to subsidising the cost of remanufactured products. The results show that when the level of subsidy is high, government subsidies for remanufactured product costs, while yielding greater environmental benefits and social welfare compared to subsidies for investment in remanufacturing technology innovation, have a lesser impact on the advancement of remanufacturing technology.
再制造闭环供应链作为循环经济的一部分，能够有效应对环境资源恶化和资源供应有限的问题。政府补贴是推动其发展的重要因素。本文考虑一个两阶段再制造闭环供应链，其中零售商负责回收，制造商将基于生产者延伸责任制度进行再制造技术创新。研究构建了以制造商为领导者的斯塔克尔伯格博弈模型，并比较了两种补贴策略对供应链决策（即再制造技术创新投资补贴和再制造产品成本补贴）的不同影响。进行了数值分析，以直观展示补贴对闭环供应链成员决策、环境效益和社会福利的影响。研究结果表明，当补贴水平较低时，政府对再制造技术创新投资的补贴能够加速再制造技术升级，与补贴再制造产品成本相比，带来更高的环境效益和社会福利。结果显示，当补贴水平较高时，政府对再制造产品成本的补贴虽然与再制造技术创新投资补贴相比能产生更大的环境效益和社会福利，但对再制造技术进步的影响较小。
