Abstract: We use game-theoretic models to study how to motivate and restrict suppliers to achieve win-win by long-term payment mechanism based on contract objective and short-term payment mechanism according to actual capability, under the circumstances that the information of the capability and the cost of suppliers are not available to the buyer side. The optimal contracts are characterized with the Revelation Principle. In addition，it is proved that the proposed optimal contract is independent of ex-ante beliefs，which the buyer has on the capability and the cost of the supplier.

Key words: supplier payment incentive, mechanism design, game theory
