Research On Cross-border Supply Chain Network Financial Risk Diffusion Mechanism

With the development of economic globalization,the market environment is no longer limited to a single country or region,and globalization of resource allocation is an inevitable trend.In recent years,many companies have implemented strategic layouts around the world in order to achieve optimal allocation of production factors,and built cross-border supply chains to enable companies to maximize cost reduction.As a result,a cross-border supply chain network with these enterprises as the core,connecting the upstream supply chain and the downstream distributors in an orderly and closely linked supply has been formed.With the development of core enterprises,the network of cross-border supply chains is getting larger and larger.Different enterprises in the network belong to different countries.At the same time,each node enterprise is an economic entity,and they can belong to different competitive supply.Chain networks,they can have their own target strategies,business methods,consumer groups,and innovative technologies,etc.,and there is no need to maintain complete consistency with cross-border supply chain networks.All of this increases the complexity and uncertainty of cross-border supply chain network management.Therefore,when the node companies in the cross-border supply chain network experience financial risks,if no preventive measures are taken,financial risks can easily follow the cross-border The proliferation of supply chain networks affects every enterprise in a cross-border supply chain network.Therefore,this article studies the spread of financial risks in cross-border supply chain networks,hoping to provide some help for multinational companies to manage cross-border supply chains.This article first introduces the relevant theory of cross-border supply chain and the theoretical basis of financial risk diffusion,and then analyzes the network structure of cross-border supply chain from a theoretical point of view,and believes that it conforms to the scale-free network structure in complex networks;The influencing factors of diffusion in the cross-border supply chain network were analyzed,and 15 risk assessment indicators were summarized,and these indicators were divided intofour categories,including external environmental risks,overall operation risks,supply dependence risks,and enterprise management risks;According to these 15 risk assessment indicators,the cross-border supply chain is scored,and the parameters that affect the spread of financial risk are obtained.The infectious disease model in the medical field is introduced,and the model of the spread of financial risk in the cross-border supply chain network is established;The degree of the node enterprise,the risk transmission rate of the enterprise,the risk immunity rate,the immune loss rate and the cure time of the enterprise have analyzed the diffusion mechanism of financial risk,and summarized the impact of each parameter of the node enterprise on the financial risk;according to different The diffusion mechanism at this stage selects the best prevention of financial risk diffusion at this stage Strategy,and then use Matlab R2017 a to analyze and verify the conclusions drawn in the paper;finally apply the research findings to the research and analysis of a cross-border supply chain of an automobile company in Hebei Province,and according to the financial risk diffusion in the cross-border supply chain network The actual situation proposes specific systematic countermeasures to prevent the spread of financial risks.
