摘　　要：分析了非对称信息对物资供应影响的原理,分别建立了不同条件下预期供应量和供应成本模型,用预期效用理论对非对称信息的影响进行了定量评估,说明信息非对称导致了供应量下降和成本的上升.实例仿真验证了模型的有效性,说明了需求信息的共享对物资供应的重要意义,最后给出了物质供应中各方的应对策略.The theory of impact of asymmetric information on material supply was analyzed,also models of optimum expected supply capacity and supply cost were presented in different conditions.The impact of asymmetric information was assessed by expect utility,which implies asymmetriy reduces supply capacity and increases the cost.The simulation of examples proved validity of the model and the importance of information share to in material supply.Lastly,strategies were given to every parts in material supply.
