Abstract: To solve the contracts of supply chain with double sided asymmetric information,on a supply chain consisted of one manufacturer with private information-marginal manufacturing cost and one retailer with private information-market demand,an incentive model with double sided asymmetric information was constructed by introducing a non-profit third party.Through solving the incentive model,a combination of transfer payment and trading quantity was obtained.To make the transfer payment specific,the wholesales contract and the sales rebate contract were provided.The research showed that the sales rebate contract could balance the information advantage of manufacturer and retailer,which was the key problem to set out the contract in supply chain with double sided asymmetric information.A numerical example was presented to explain the main ideas.

Key words: double sided asymmetric information, supply chain contract, wholesale price contract, sales rebate contract
