Abstract: Aiming at the supplier's information leakage problem in supply chain,the leakage motivation of suppliers and the information management strategy of other supply chain's members under the threat of leakage behavior were discussed.In a setting of multi-period,a supply chain which consisted of a supplier,an incumbent and an entrant retailer was considered,and only the incumbent had demand information in advance.The incumbent decided whether to share demand information with the supplier,and the supplier decided whether to leak the information to the entrant.The separating and pooling strategy were chose separately by incumbents to share and conceal the demand information.The research result showed that the incumbents would choose pooling strategy when greater probability and smaller demand coefficient variation of low demand were appeared;otherwise,separating strategy would be chosen.Information transmission in the supply chain was controlled successfully with incumbent's reasonable strategy,and expected profits maximization was realized simultaneously.

Key words: information leakage, supply chain information management, separating strategy, pooling strategy
