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 de-centralized decision-making respectively,and it also analysed the action mechanism among manufacturer's optimal carbon emission re-duction 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 re-lationship 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 du-al-channel supply chain.
