Research on Supply Chain Network Risk Management Based on Multi-layer Complex Network Model

As necessities in people's lives, the stability and quality safety of the production and circulation of agricultural products are widely of concern to the whole society. With the development of economic globalization, networking and informatization, the structure and dynamic behaviour of the agricultural product supply chain are becoming increasingly complex. A concept increasingly central to supply chain theory is sustainability. As the frontier of network science, complex network theory provides a new method to study complex real networks. This paper adopts the complex network theory to explore the formation and evolution mechanism of the agricultural product supply chain network and the risk propagation mechanism on the supply chain network through modelling and simulation. On this basis, it proposes the control strategy of risk propagation. The research in this paper can enrich the results of complex network theory in the field of supply chain based on ecological theory. The network model construction can reveal the formation and evolution mechanism of the agricultural product supply chain network. The analysis of risk dynamics can provide a theoretical basis and practical guidance for controlling risk propagation of agricultural product supply chain networks.
