供应链为其上下游相关企业提供了一个互动平台。生态学理论认为供应链上下游企业的互动主要包括竞争、合作和依赖关系。基于上述理论分别构建企业互动关系模型,运用微分方程定性知识对不同模型稳定性进行分析,为模拟以及预测分析供应链组织结构演化提供了理论依据。
Supply chain provides correlative enterprises from upstream and downstream with a platform of interaction. This paper considers that the interactive relationship of enterprises in the supply chain includes three modes, namely competition, cooperation and parasitism. Then it presents different models of three interactive relationships, and analyzes stability of interaction about two enterprises by theory of differential equation. Results obtained by this paper can help forecast and analyze the evolution about organization structure of supply chain and further reveal the mechanism of interaction among enterprises in the supply chain.
