| 中文摘要 |
| 为促进低碳循环经济发展，政府对制造/再制造产业采取补贴和碳税政策，两政策实施目的虽相同，但作用机理却不同。为探讨政府补贴和碳税双重政策对制造/再制造的影响，运用博弈理论构建了外包再制造闭环供应链（CLSC）模型，并对比分析双重政策与单一政策对CLSC最优均衡的影响及差异。结果表明：相较于单一补贴政策，若政府设定的补贴与碳税之间比值大于一阈值时，双重政策更有利于扩大CLSC市场空间，提升产品总销量；相较于单一碳税政策，当再制造经济性与碳税满足特定关系时，双重政策更有利于提高废旧产品回收率及再制品销量；双重政策可增加企业利润，但并不一定有利于提高消费者剩余与社会福利。且再制品折价或再制造工艺水平的提高，均可提升政府政策的实施效果。 |
| 英文摘要 |
| In order to promote the development of a low-carbon circular economy, the government adopts subsidies and carbon tax policies for the manufacturing/remanufacturing industry. Although both policies have the same purpose, their mechanisms differ. To explore the impact of the government's dual policies of trade-in subsidies and carbon tax on manufacturing/ remanufacturing, a closed-loop supply chain model of outsourcing remanufacturing (CLSC) was constructed based on game theory, and the effects and differences of dual and single policies on the equilibrium of CLSC were compared and analyzed. The results show that dual policies when the subsidy-to-carbon tax ratio exceeds a threshold and outperforms single subsidies in expanding the market space of CLSC and increasing the total sales of products. Compared with the single carbon tax policy, when the remanufacturing economy and carbon tax meet specific conditions, the dual policies will promote recovery rates and the sales volume of remanufactured products. Dual policies can increase firms profit, but may not necessarily improve consumer surplus and social welfare. Improving the discount of remanufactured products or remanufacturing technology can enhance government policies' effectiveness. |
