Considering the preference of green consumers for remanufactured products, a dual-sale-channel supply chain model with government non-intervention, government remanufacturing subsidy policy, and carbon tax policy is constructed, respectively. The difference of the optimal decision between the firm and the government under the two policies is discussed in this paper. Meanwhile, we analyze the influence of green consumers on the government's optimal decision, based on social welfare maximization. It is found that without government intervention, social welfare is the lowest. The carbon tax policy is better when the proportion of green consumers and the environmental coefficient are extreme or moderate at the same time. Otherwise, the subsidy policy is better. The carbon tax policy is more effective than the subsidy policy in controlling carbon emissions. Profit-sharing contracts should be established by enterprises and governments to achieve win⁻win results.
考虑到绿色消费者对再制造产品的偏好，分别构建了政府不干预、政府再制造补贴政策和碳税政策下的双销售渠道供应链模型，讨论了这两种政策下企业和政府最优决策的差异。同时，基于社会福利最大化，分析了绿色消费者对政府最优决策的影响。结果表明，在政府不干预的情况下，社会福利最低。当绿色消费者的比例和环境系数同时处于极端或中等水平时，碳税政策更好。否则，补贴政策更好。碳税政策在控制碳排放方面比补贴政策更有效。企业和政府应建立利润共享合同，以实现双赢。
