碳税政策下的双渠道供应链碳减排技术创新协作策略

The collaborative strategy for carbon reduction technology innovation on dual-channel supply chain under the carbon tax policy

在碳税政策下,针对制造商直销渠道和零售商传统渠道的产品销售价格存在差异及消费者低碳偏好,通过构建双渠道供应链碳减排技术创新投入博弈模型,研究零售商订货与制造商碳减排技术创新投入的决策问题.研究结果表明:通过两部定价契约和转移支付补偿契约可以实现双渠道供应链系统的协调.与制造商单独碳减排技术创新投入情形相比较,碳减排技术创新投入成本分担情形下双渠道销售总量、碳减排率更高.双渠道供应链系统利润的大小取决于零售商分担碳减排技术创新投入比例的大小;双渠道销售总量、碳减排率、制造商利润和双渠道供应链利润随着碳税增加而增加,而零售商利润随之降低;碳减排率和双渠道销售总量随着渠道竞争强度的增加而降低,制造商利润、零售商利润以及双渠道供应链利润随着渠道竞争强度的增加则先降后增;双渠道销售总量、碳减排率、制造商利润和双渠道供应链利润随着消费者低碳偏好的增加而增加,而零售商利润则随之先降后增.

Considering the difference of dual-channel product prices and consumers'low carbon preference under carbon tax policy,using the game model of carbon reduction technology innovation investment on dual-channel supply chain,the decisions of a retailer's order quantity and a manufacturer's carbon reduction innovation investment are studied.The results show that the dual-channel supply chain can be coordinated with two part tariff contract and transfer payment compensation contract.The total sale quantity of dual-channel and carbon reduction rate will be higher under the case of cost-sharing of carbon reduction technology innovation investment compared to the case of individual carbon reduction technology innovation investment,and the dual-channel supply chain profit depends on the proportion of retailer's cost-sharing on the carbon reduction technology innovation investment.The total sale quantity of dual-channel,carbon reduction rate,manufacturer's profit and supply chain profit will increase positively with the carbon tax,while the retailer's profit will reduce.The carbon reduction rate and total sale quantity of dual-channel will reduce negatively with the channel competition strength,but manufacturer's profit,retailer's profit and dual-channel supply chain profit will decrease first and then increase.The total sale quantity of dual-channel,carbon reduction rate,manufacturer's profit and supply chain profit will increase positively with the consumers'low carbon preference,but the retailer's profit will decrease first and then increase.
