中文摘要：

为分析非对称信息下供应链契约中的制造成本信息对决策者的决策和供应链利润的影响,主要考虑销售商为主、制造商为从的两级供应链,在生产成本为制造商私人信息的假设下,研究生产成本的分布与最优生产量、供应链利润和制销双方利润分配的关系。结果表明,在其他条件不变的情况下,销售商对制造商的单位生产成本分布斜率的估计越大,最优生产量和供应链利润的扭曲越小,制造商的利润随之增加;销售商关于制造商的单位生产成本的估计区间越小,生产量和供应链的利润扭曲越小,双方利润水平趋于对称信息情况下的水平。通过算例和图形对结论进行了说明。

英文摘要：

To analyze the influence of manufacturing cost information on decision-making and supply chain profit in supply chain contract under asymmetric information,a two-echelon retailer-led supply chain was considered.Under the assumption of manufacturer’s production cost was his private information,the relationship between production costs’ distribution and optimal production,supply chain profits and profit allocation was studied.The results showed that the greater the likelihood of high cost in the case of other conditions remain unchanged,the smaller the distortion of output and the supply chain profits,whereas the manufacturer’s profit increase correspondingly;the smaller the estimated range of unit production cost,the smaller the distortion of output and the supply chain profits,the profit level of the two sides tended to the symmetric information level.The conclution was illustrated by numerical example and figures.
