| dc.description.abstract | Progress of technology and development of economy make market prediction more difficult, the change intensity of demand information is quicker and quicker, every enterprise is more difficult to survive. So this paper is studied supplies with the coordination problem of the information sharing among chain members to analyze and solve information asymmetry of the perishable supply chain.
The paper takes single manufacturer and retailer to go on a two-echelon supply chain model, to study best decision and income of one manufacturer and retailer under this supply chain. According to information sharing, it analyzes whether a retailer will offer free information first. The manufacturer’s performance will improve by the free information sharing, but we all find out that free information sharing will bring down the market performance of supply chain. So the retailer will not share the information for free. The manufacturer in order to solve the result and reducing the problem of information asymmetry, it excepts that the retailer will like to share information to the supplier by mechanism design and make it raise his own profit, supply chain profit, and coordinate and supply the chain.
Finally, in three kinds of mechanisms, linear and non-linear price quantity discount mechanism can coordinate to supply chain. Under the circumstances, these two kinds of mechanisms can both achieve the goal, and then analyze the manufacturer and the retailer movements in the market. And through the result of comparative analysis finally, getting though can reach information to share with the result of supplying chain coordination. In the linear quantity price discount, the manufacturer must pay more information cost, but it is efficiency mechanism; and if the manufacturer chooses the non-linear quantity price discount, it can guarantee the highest market profits of the manufacturer. So from these two respects discusses how manufacturers should be chosen mechanisms.
