Joint Emission Reduction Strategies and Coordination Mechanism Disturbed by Dynamic Demand in a Dual-channel Chain
As the quality of the environment decreases,enterprises and consumers'awareness of environmental protection constantly improves.More and more enterprises begin to increase their investment in carbon emission reduction and attract environmentally friendly consumers to buy low-carbon products through advertising.The results can provide a theoretical basis for the joint emission strategy of supply chain members in a low-carbon environment.In this paper,a dual-channel low-carbon supply chain composed of a manufacturer and a retailer is taken as a research object.Firstly,an uncertain market demand is assumed to be dynamically influenced by product emis-sion reduction and retailers'low-carbon advertising,and the demand model is extended.Secondly,based on the differential game theory,the optimal solution of the dual-channel supply chain under strategic alliance,decen-tralization and cooperation are analyzed.Thirdly,the Shapley value method is used to realize the coordination of dual-channel low-carbon supply chain.Finally,the related properties are analyzed and verified by simulation.The main results show that:1)The joint emission reduction strategy has played a positive role in the dual-channel supply chain,making the profits of its members and the whole continuously rise.2)Strategic alliance is the best strategy,realizing the Pareto optimality of low-carbon supply chain.At the same time,under certain conditions,the cooperative advertising and cost-sharing contract for emission reduction are more effective than the cooperative advertising contract.The stronger the consumers'preference for direct sales channels and low-carbon products is,the greater the possibility of supply chain members adopting the cooperative contract is.3)The wholesale price and customer's channel loyalty have a significant influence on the retailer's optimal strategy.4)The application of the Shapley value method can effectively distribute the excess profits under the strategic alliance according to the contribution rate of manufacturers and retailers,and realize the system coordination.This paper will focus on the analysis of the optimal strategy when the manufacturer is the game leader.How-ever,in management practice,with the continuous growth of retailers,they will also become the leader of the secondary supply chain,such as e-commerce giants like Suning and Jingdong.Therefore,whether this situation will change is a question that needs to be further discussed.Secondly,this paper suggests that consumers are active advocates of low-carbon products.However,in real life,for some price sensitive people,the price of low-carbon products is generally high,so they will not choose to buy them.Therefore,for enterprises,how to consider consumer heterogeneity in pricing strategies and advertising and marketing strategies is also the direction of future research.
