Research On Demand Information Sharing Strategy Of Supply Chain Based On Manufacturer Competition

With the rapid development of information technology,information sharing,as a strategy to promote the cooperation among enterprises and improve supply chain's performance,has been attached wide attention by the industry.However,in the environment of rapid economic development,the competition among the same industries is becoming more and more intense,and there are still many shortcomings in the realization of information sharing.Based on this situation,this paper takes a supply chain composed of two competitive manufacturers and one common retailer as the research object,and respectively studies the influence of different information sharing strategies on pricing decisions and profits of supply chain members under unilateral partial information sharing and bilateral information sharing.Firstly,we consider unilateral partial information sharing,which is only the retailer has demand forecast information and chooses part information to share with different number of manufacturers.The manufacturer-led Stackelberg pricing decision models under three strategies are established,which are the retailer sharing partial information with two manufacturers,the single manufacturer and the non-sharing information models,and the equilibrium solutions are obtained by backward induction.Through analyzing and comparing the equilibrium solutions under different strategies,we draw some conclusions.First of all,partial information sharing has a positive effect on the optimal prices,and the positive effect increases with the increase of competition intensity between two manufacturers and the amount of information shared.Beside,whether the retailer shares partial information with two manufacturers or with a single manufacturer,each supply chain member can benefit from information sharing under certain conditions,and all supply chain members are more likely to benefit from information sharing when the retailer shares partial information with two manufacturers.Secondly,considering that two manufacturers and the retailer all have demand forecast information,we analyse the influence of bilateral information sharing on pricing strategies and the expected profits.The manufacturer-led Stackelberg pricing decision models under three information sharing strategies are established.First,we study the influence of each member's demand forecast information on the optimal price strategies.Second,the effects of bilateral information sharing on the expected profits of the whole supply chain and its members are discussed.Third,the effects ofmain parameters on expected profit are also studied.The results show that information sharing reduces the positive effect of manufacturers' demand forecasts on the optimal prices,while it increases the positive impact of retailer's demand forecast on the optimal prices.Bilateral information sharing increases the expected profits of two competitive manufacturers and decreases the expected profit of the retailer,while it increases the whole supply chain's expected profit under certain conditions.
