Diffusion Mechanism of Supply Chain Emergency

The specific transmission and diffusion of emergency in supply chain is determined by the characteristics of complexity, multitudiousness and diversification of stakeholders of supply chain. This paper analyzed the diffusion traits, patterns and influencing factors of emergency in supply chain. The incubation period, fast outbreak period and slow diffusion mechanism of emergency in supply chain are also analyzed on the basis of diffusion traits and patterns. Theoretical models of emergency diffusion are established in the way of homology. Emergency strategies are put forward to provide theoretical basis for decision makers.
