碳交易机制下双渠道供应链定价决策研究

Research on Pricing Decision in Dual-Channel Supply Chain under Carbon Trading Mechanism

了解碳交易价格对双渠道供应链决策的影响有助于企业在线上线下销售渠道并存的情况下提升科学经营管理能力。本文在考虑消费者低碳偏好的基础上,建立碳限额交易机制下集中决策和分散决策两种情形的双渠道供应链博弈模型,比较研究两种情形下碳交易价格对双渠道供应链定价决策的影响。研究发现:两种决策下的供应链利润、产品销售价格、供应链销量和单位碳减排量均随碳交易价格变化;设计基于减碳成本共担的收益共享契约,实现供应链成员利润的帕累托改进,最后通过算例验证以上研究结论的合理性。

Knowing the impact of carbon trading prices on dual-channel supply chain decisions can help companies improve their scientific management capabilities when online and offline sales channels coexist.In this paper,we consider the impact of carbon trading price on supply chain decision.In this paper,based on the low carbon preference of consumers,we develop a two-channel supply chain game model under the carbon cap-and-trade mechanism.This paper compares the impact of carbon trading price on the pricing decision of dual-channel supply chain in two scenarios:centralized decision making and decentralized decision making.This paper compares the impact of carbon trading price on the pricing decision of dual-channel supply chain under the two scenarios.The study finds that the supply chain profit,product sales price,supply chain sales volume and unit carbon emission reduction under the two scenarios are all different with the carbon trading mechanism.The study finds that the supply chain profit,product sales price,supply chain sales volume and unit carbon emission reduction vary with the carbon trading price under the two decisions;the profit sharing contract based on carbon reduction cost sharing is designed to realize the Pareto improvement of supply chain members'profit.The study finds that the supply chain profit,product sales price,supply chain sales volume and unit carbon emission reduction vary with the carbon trading price under both decisions.
