碳限额及交易下零售商低碳宣传的双渠道供应链决策与协调

Decision and Coordination of Dual-channel Supply Chain Considering Retailer’s Low-carbon Promotion in the Carbon Cap and Trade Mechanism

在碳限额及交易下,考虑制造商碳减排技术投入和零售商低碳宣传,分别构建了无低碳宣传成本分摊、低碳宣传成本分摊的分散决策和集中式决策博弈模型通过对模型的分析,指出通过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:在碳限额及交易机制下,碳减排率与碳排放交易价格成正向变化关系,低碳宣传水平、双渠道供应链利润与碳排放交易价格成U变化关系;碳减排率、低碳宣传水平、双渠道供应链利润与消费者低碳偏好系数、低碳宣传对消费者的影响系数都成正向变化关系;碳减排率、低碳宣传水平、双渠道供应链利润都与低碳宣传成本、碳减排成本系数成反向变化关系.

Considering the carbon emission reduction technology investment and the lowcarbon promotion of retailer under carbon cap and trade,the game models of decentralized decision-making with no low carbon promotion cost allocation or low carbon promotion cost allocation and centralized decision-making are established respectively in the dual-channel supply chain.The models are analyzed,and it is also pointed out that the coordination of dualchannel supply chain can be achieved with retailers sharing manufacturers’ carbon emission reduction cost and manufacturer sharing retailers’ low carbon promotion cost.The results indicate that the carbon reduction rate is positively related to carbon emission trading price,low carbon promotion level and dual channel supply chain profit are an U-shaped relationship with carbon emission trading price.The carbon reduction rate,low carbon promotion level and dual channel supply chain profit are positively related to consumer’ low carbon preference and influence coefficient of low-carbon promotion to consumer.The carbon reduction rate,low carbon promotion level and dual channel supply chain profit are inversely related to cost coefficient of low-carbon promotion and cost coefficient of carbon emission reduction.
