Remanufacturing has attracted much attention for its enormous potential in resource recycling and low-carbon emission reduction. To investigate the effects of different government intervention policies on remanufacturing and carbon emissions, two profit maximization models of the capital-constrained manufacturer under carbon tax and low-carbon credit policies are constructed respectively. Then, through theoretical and numerical analyses, some significant findings are drawn: (1) Both carbon tax and low-carbon credit policies can encourage capital-constrained manufacturers to produce more remanufactured products, but which intervention policy is more advantageous also depends on the carbon emission cost of new products or financing cost of the remanufactured products. (2) Although carbon tax policy can effectively control carbon emissions, it is always at the expense of both capital-constrained manufacturers and consumers; while low-carbon credit policy can help capital-constrained manufacturers achieve the goal of win-win economic and environmental benefits when the remanufacturing carbon savings advantages are more apparent. (3) From the perspective of consumer benefits, carbon tax is more advantageous when the consumer willingness to pay for remanufactured products is higher; otherwise, low-carbon credit policy should be implemented. (4) The higher the environmental damage coefficient is, the more it can highlight the advantages of the two intervention policies in social welfare enhancement, especially the carbon tax policy; and when the environmental damage coefficient is given, the stronger the consumers' willingness to pay for remanufactured products is, the more it is conducive to reducing the negative effects caused by the carbon tax or low-carbon credit policy in social welfare enhancement, or increasing the corresponding positive effects. Based on above findings, some managerial insights and policy implications are provided to capital-constrained manufacturers and policy-makers.
再制造因其在资源回收和低碳减排方面的巨大潜力而备受关注。为了研究不同政府干预政策对再制造和碳排放的影响，分别构建了资本约束型制造商在碳税政策和低碳信贷政策下的两个利润最大化模型。然后，通过理论和数值分析，得出了一些重要结论：（1）碳税政策和低碳信贷政策都能促使资本约束型制造商生产更多的再制造产品，但哪种干预政策更具优势还取决于新产品的碳排放成本或再制造产品的融资成本。（2）虽然碳税政策能有效控制碳排放，但这总是以牺牲资本约束型制造商和消费者为代价；而当再制造的碳节约优势更为明显时，低碳信贷政策能帮助资本约束型制造商实现经济和环境效益双赢的目标。（3）从消费者利益的角度来看，当消费者对再制造产品的支付意愿较高时，碳税政策更具优势；否则，应实施低碳信贷政策。（4）环境损害系数越高，越能凸显这两种干预政策在提升社会福利方面的优势，尤其是碳税政策；并且在给定环境损害系数的情况下，消费者对再制造产品的支付意愿越强，就越有利于减少碳税或低碳信贷政策在提升社会福利方面所带来的负面影响，或增强相应的正面影响。基于上述研究结果，为资本约束型制造商和政策制定者提供了一些管理启示和政策建议。
