展厅效应下双渠道供应链的减排投资与协调策略研究

低碳经济的发展改变了双渠道供应链的决策环境，同时也改变了一些消费者的低碳偏好。在考虑展厅效应和消费者低碳偏好的基础上，构建碳交易机制下双渠道供应链的减排和服务运营决策模型，利用主从博弈分别求解集中决策和分散决策情形下的最优运营策略，分析制造商的最优减排率、零售商的最佳服务水平及渠道价格之间的作用机制。进一步设计服务成本分担契约解决碳交易政策下分散式双渠道供应链的双重边际效应问题，探究展厅效应、低碳偏好及成本分摊对供应链的影响。研究表明，单位碳交易价格会影响展厅效应与减排率的作用关系，通过调节渠道价格比可以提高减排率和零售商销售价格，服务成本分担契约能够使双渠道供应链实现帕累托改进。

Carbon Emission Reduction Investment and Coordination Strategies ofDual channel Supply Chain under the Showrooming Effect

The development of low carbon economy has changed the decision making environment of dual channel supply chain, and it also changed the low carbon preference of some consumers. Considering showrooming effect and consumers low carbon preference, this paper constructed a decision making model of carbon emission reduction and service operations for a dual channel supply chain under carbon trading mechanism. By using Stackelberg game, this paper solved the optimal operation strategy under the centralized and decentralized decision making respectively, and it also analysed the action mechanism among manufacturers optimal carbon emission reduction rate, retailers optimal service level and channel price. Service cost sharing contract was further designed to solve the double marginalization of decentralized dual channel supply chain under carbon trading policy to explore the influence of showrooming effect, low carbon preference and cost sharing on the supply chain. The research results show that the unit carbon trading price affects the relationship between the showrooming effect and the carbon emission reduction rate. By adjusting the channel price, the carbon emission reduction rate and retailers selling price can be improved. The service cost sharing contract can achieve Pareto improvement of the dual channel supply chain.
