碳限额及交易下低碳补贴和低碳宣传成本分摊的双渠道供应链联合减排策略

为了研究碳限额及交易下考虑低碳补贴和零售商低碳宣传的双渠道供应链联合减排策略问题,构建由一个制造商和一个零售商组成双渠道供应链,分别建立碳减排补贴与低碳宣传的双渠道供应链集中式决策模型以及无碳减排补贴且无低碳宣传成本分摊、有碳减排补贴但无低碳宣传成本分摊、碳减排补贴且低碳宣传成本分摊的双渠道供应链分散式决策模型,分析其最优决策,并指出政府碳减排补贴、碳减排成本和低碳宣传成本分摊能够实现双渠道供应链协调。研究结果表明,在碳限额及交易下,最优碳减排率、最优低碳宣传水平和双渠道供应链利润与政府补贴比例、低碳偏好对需求的影响系数、低碳宣传对线上消费者需求的影响系数、低碳宣传对线下消费者需求的影响系数都成正向变化关系;最优碳减排率、最优低碳宣传水平和双渠道供应链利润与低碳宣传成本系数、最优碳减排成本系数成反向变化关系;最优碳减排率与碳排放交易价格成正向变化关系,而最优低碳宣传水平、双渠道供应链利润与碳排放交易价格成反向变化关系。

Dual-channel Supply Chain Cooperative Emission Reduction Considering Subsidies and Promotion Cost Allocation in the Carbon Cap and Trade Regulation

In order to study the cooperative emission reduction strategy of dual-channel supply chain considering low carbon subsidies and low carbon publicity of retailers under carbon cap-and-trade,a dual-channel supply chain consisting of a manufacturer and a retailer is constructed.The models of centralized decision-making with carbon emission reduction subsidy and low carbon publicity,and the models of decentralized decision-making with no carbon emission reduction subsidy and no low carbon publicity cost allocation,and carbon emission reduction subsidy but no low carbon publicity cost allocation,carbon emission reduction subsidy and low carbon publicity cost allocation are respectively established in the dual-channel supply chain,and the optimal decision analyzed.It is pointed out that the coordination of dual channel supply chain can be achieved with government's carbon reduction subsidy,allocation of carbon emission reduction cost and low carbon promotion cost.The results indicate that optimal carbon reduction rate,optimal low carbon promotion level and dual channel supply chain profit are positively related to government subsidy ratio,the influence coefficient of low-carbon preference on demand,the influence coefficient of low-carbon promotion on online consumer demand,and the influence coefficient of low-carbon promotion on offline consumer demand.The optimal carbon reduction rate,optimal low carbon promotion level and dual channel supply chain profit are inversely related to the cost coefficient of low carbon promotion and carbon emission reduction.The optimal carbon emission reduction rate is positively related to carbon emission trading price,but optimal low carbon promotion level and dual channel supply chain profit are inversely to carbon emission trading price.
