摘要
考虑"碳税+碳交易"并行的混合碳政策,对供应链中上游制造商碳减排和再制造、下游零售商低碳宣传的联合减排问题展开分析.将低碳商誉水平作为状态变量,构建了 3种微分博弈决策模型来分析混合碳政策,以及决策模式对成员决策、利润、低碳商誉和碳排放总量的影响.结果表明:与现有碳交易政策相比,混合碳政策可以从长期角度进一步激励制造商的低碳行为、提升产品的低碳商誉,但不会影响零售商的低碳宣传水平.此外,供应链决策模式会影响混合碳政策的实施效果.如果政府制定合理的碳税价格,与分散决策模式相比,供应链成员采取集中决策模式能够进一步扩大低碳产品需求、提升环境正外部性.最后,改进的双向成本分担契约可以实现供应链的完美协调.
Abstract
Considering"carbon tax and cap-and-trade"regulations,this paper analyzed the joint emission reduction decision-making in the supply chain.Consistent with reality,a two-echelon supply chain model consisting of a leading manufacturer and a retailer was proposed,where the upstream manufacturer depended on remanufacturing and the green technology to reduce carbon emissions,and the downstream retailer conducted relevant low-carbon promotions.By taking the low-carbon goodwill as a state variable,three differential game decision-making models were constructed to analyze the impacts of hybrid carbon regulations and different decision-making models on decisions,low-carbon goodwill,profits,and total carbon emissions.The results show that compared with the existing cap-and-trade regulation,the implementation of hybrid carbon regulations can further encourage low-carbon behaviors of the manufacturer and enhance the low-carbon goodwill from a long-term perspective,but will not affect the retailer's low-carbon promotion decision-making.In addition,the supply chain decision-making mode will affect the effectiveness of hybrid carbon regulations.If the government sets a reasonable carbon tax price,compared with the decentralized decision-making mode,the centralized decision-making mode can further expand the demand for low-carbon products and enhance the positive environmental externality.Finally,the improved two-way cost-sharing contract can achieve perfect coordination of the supply chain.The results provide valuable reference for different members and the government.
