Research On The Construction Of Cyber-resilience In Supply Chain Under Internet Scurity Threat

Actually,the rapid development of the global information construction.Computer,communications,cyber as the representative of the Internet technology in economic construction,business management and other fields play a very important role.The application of Internet information technology in the supply chain helps enterprises share information,improves efficiency and reduces costs,so as to achieve more effective supply chain management.However,the birth and development of Internet technology and the extensive use of it,it also brings people the corresponding cyber-security threats.Since the increasing dependence of the supply chain enterprises on the Internet information technology,the security problems of the Internet seriously threaten the cyber-security of the supply chain.Face of the endless cyber-security risk in the supply chain,the researchers began to pay attention to the recovery ability of the supply chain under the influence of the cyber-security risk,and put forward the concept of the cyber-resilience of the supply chain.Although all the enterprises in the supply chain are increasing the budget of the cyber-resilience investment,the effect is not obvious.Therefore,under the influence of the cyber-security risk of the supply chain,the cyber-resilience construction investment decision of the enterprises in the supply chain is an important and difficult problem for the managers and the academic circles to study.Based on the theory,cyber-security risk in the supply chain in the Internet security threat as the main line,using the game theory model to analyze the impact of the ability risk and the relationship risk in supply chain on the cyber-resilience construction investment level of the supply chain.First of all,through the study of the existing literatures on the traditional risk of supply chain,the cyber-security risk in the supply chain and the cyber-resilience of the supply chain to understand the domestic and foreign research status.Secondly,expounding the cyber-security risk of the supply chain concept and characteristics and sources,and according to the sources of risk to classify cyber-security risk in the supply chain as the enterprise internal capability risk of supply chain,the relationship risk between enterprises in supply chain and the external cyber environment security risks of supply chain.Thirdly,this paper expounds the cyber-resilience of supply chain and analyzes the influence of the cyber-security risk of the supply chain on the cyber-resilience construction investment decision of theenterprises in the supply chain.Through the game theory model to research the influence of the credibility effect of the ability risk and the cyber-vulnerability and integration of the relationship risk in supply chain on the cyber-resilience construction investment level of the supply chain.Research shows that the credibility effect of the ability has incentive effect on the cyber-resilience construction investment under the condition of non cooperative game,but its influence is determined by the level of enterprise's cyber-resilience in the case of cooperative game.The degree of integration in the relationship risk,whether in the case of non cooperative game or cooperative game,has an incentive effect on the cyber-resilience construction investment in supply chain.The ability risk leads to excessive investment in the cyber-resilience construction,and the relationship risk makes the investment rate of enterprises to the cyber-resilience construction low.Fourthly,this part is the digital simulation of the game in the third part,and concretely analyzes the influence of the cyber-security risk of the supply chain on the investment decision making of the cyber-resilience construction.Finally,summarizing the paper and putting forward some corresponding suggestions.
