价格随机下,采购执行业务中物流企业承担中小企业违约风险,为有效降低其面临的业务风险,文章应用回购策略及风险分担、供应链协调理论,设计了采购执行风险分担模型,并确定了风险自担与风险分担两种模式下的最优贷款价值比,在此基础上,通过设计合理契约参数,实现共同分担业务风险的合理模式,进而可以降低风险自担模式下信息不对称或信息不完全条件下所产生的业务风险,保证各方实现更大的收益。研究表明,一定条件下,合理的回购参数可以达到帕累托最优,进而协调供应链,为设计价格随机下采购执行业务契约提供了科学依据。
In order to effectively reduce the business risk faced by small and medium-sized enterprises, the logistics enterprises in purchasing and executing business randomly assume the risk of default. The paper applies the repurchase strategy and risk sharing and supply chain coordination theory to design a risk-sharing model for purchasing execution and determines Risk and risk-sharing two modes of optimal loan value ratio, on this basis, through the design of reasonable contract parameters, to achieve a reasonable sharing of business risk model, which can reduce the risk of information asymmetry or information model Business risks arising under incomplete conditions ensure greater benefits for all parties. The research shows that under certain conditions, the reasonable repurchase parameters can reach the Pareto optimality, and then coordinate the supply chain, which provides a scientific basis for the implementation of the business contract under the random purchase price under the design price.
