碳限额及交易下制造商低碳宣传的双渠道供应链决策与协调

在碳限额及交易下考虑碳减排技术投入和制造商低碳宣传，分别建立了零售商不参与制造商低碳宣传计划、参与制造商低碳宣传计划的分散式决策和集中式决策的博弈模型，并指出零售商分摊制造商碳减排成本和低碳宣传成本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、低碳宣传水平和双渠道供应链利润都与消费者低碳偏好对需求的影响系数、低碳宣传中宣传零售商品牌元素对线上线下需求的影响系数、低碳宣传对线上线下消费者需求的影响系数成正向变化关系；碳减排率与碳排放交易价格成正向变化关系，双渠道供应链利润与碳排放交易价格成反向变化关系，而低碳宣传水平与碳排放交易价格成U变化关系；碳减排率、低碳宣传水平和双渠道供应链利润与碳减排成本系数成反向变化关系.

Decision-making and coordination of dual-channel supply chain considering manufacturer's low-carbon promotion in the carbon cap and trade mechanism

Considering the carbon emission reduction technology investment and manufacturer's low-carbon promotion under carbon cap and trade， the game models of decentralized decision-making with retailers no participating in manufacturer's low-carbon promotion plan or participating in and centralized decision-making are established respectively in the dual-channel supply chain. It is also pointed out that the coordination of dual-channel supply chain can be achieved with retailers sharing manufacturers' carbon emission reduction cost and low carbon promotion cost. The results indicate that carbon reduction rate， low carbon promotion level and dual channel supply chain profit are positively related to influence coefficient of consumer' low carbon preference on demond， influence coefficient of retailers' brand elements on online and offline demand， and influence coefficient of low-carbon promotion on online and offline consumer demand. The carbon reduction rate is positively related to carbon emission trading price， and profit of dual-channel supply chain is inversely related to carbon emission trading price， while low carbon promotion level is an U-shaped relationship with carbon emission trading price. The carbon reduction rate， low carbon promotion level and dual channel supply chain profit are inversely related to cost coefficient of carbon emission reduction.
