摘　　要：以两级供应链不完全信息共享为基本情境,建立信息共享程度与制造商、零售商的销售价格和收益的数学关系模型,并运用弹性系数量化信息共享对供应链风险传染的影响。研究结果表明,两级供应链上下游企业间的信息共享程度变动会导致价格风险呈减弱方式在供应链上传染;存在一个信息共享程度阀值,当信息共享程度偏离这一阀值时,收益风险传染强度会呈现不同的变动趋势。Based on the incomplete information sharing in a two echelon supply chain, this paper established models to show the relationship between the degree of information sharing and the sales price and revenue of manufacturers and retailers and employed elastic coefficient to quantize the impact of information sharing on supply chain risk contagion. The results show that the changes of the degree of information sharing between upstream and downstream enterprises will lead to price risk contagion in a weakening trend in the two echelon supply chain; there is a threshold of the degree of information sharing , and the intensity of revenue risk contagion will change in different trends when the degree of information sharing deviates from the threshold.
