中文摘要：

以多个供应商和一个制造商组成的上游段供应链为研究对象,考虑需求随机且对产品价格产生影响以及产品滞销价格,构建传统和VMI模式下经济效果模型,为了使利益分配结果更合理,建立了以价格补贴分配方式为起点的基于Nash谈判的收益共享契约模型。通过理论论证及算例分析,结果表明：该模型不仅克服了简单使用Nash谈判时受谈判能力影响过大的缺点,同时也保留了Nash谈判收益共享契约可以达到供应链最优收益的优点,为上游段VMI模式的实施提供了保障。

英文摘要：

This paper takes the upstream supply chain consisting of multiple suppliers and a manufacturer as the research object,considers that demand is stochastic and affects product price and the price of the product unmarketable,and constructs the economic effect model under the traditional and VMI mode.In order to make the distribution of benefits more reasonable,the paper puts price subsidy allocation as the starting point and establishes a revenue sharing contract model based on Nash negotiation.Through theoretical proof and example analysis,the results show that this model not only overcomes the shortcoming that the influence by bargaining power is too big when using Nash negotiations simply,but also retains the advantage that revenue sharing contract based on Nash negotiation can achieve optimal benefits of the supply chain.The research provides the guarantee for the implementation of the upstream section VMI mode.
