Abstract: This paper applies game theory to analyze the information sharing technology strategy of the members on the supply chain. Firstly,it constructs the expected profits models of the supplier and retailer based on two types of parameters of demand and supply uncertainty,and confirms that there are optimal solutions of the expected profits under the uncertain conditions. Secondly,it develops a game-theoretic model of three phrases in order to study the relation of information sharing technology strategies adopted by the members on the supply chain. Thirdly,it discusses four equilibrium statuses,and the result shows: If initial uncertainty is high,information withholding is a viable strategy for the retailer,but this strategy can backfire through the supplier speculating the retailer's market,the retailer will adopt an information sharing strategy when the supplier can know more about the market.

Key words: supply chain, information sharing strategy, game analysis
