An Information Sharing Model in Dual-channel Supply Chain in E-commerce Environment

This paper proposes a new information sharing model in hybrid dual-channel supply chain, which includes two retailers and one manufacturer with the electronic direct marketing. Based on whether the two retailers take part in the information sharing or not, three different information-sharing sub-models are introduced to resolve the optimal solution and analyze their stable Game Equilibrium. The optimal results and analysis show that to share uncertain demand information impacts on profits of supply chain in e-commerce environment, but it can not assure the increase in the total profit of supply chain unless under the specific conditions. The coordination between traditional channels and electronic channels is relevant to the basic demand and uncertain demand of retailers under certain conditions. The price discrimination strategy is an effective means to design information-sharing mechanism under the stable equilibrium conditions in dual-channel supply chain.
