Research On Risk Avoiding Multinational Supply Chain Decision Under The Background Of Blockchain Technology

With the development of transnational supply chain,multinational enterprises may face problems such as product quality,transaction safety and taxation,which will have a negative impact on the development of transnational supply chain.To solve this problem,some platforms have used blockchain for quality verification to build customer trust and ensure product quality.As we all know,the operation of the blockchain requires the participation of all parties in the supply chain.At the same time,supply chain members may have risk aversion behavior.Whether multinational enterprises have the motivation to verify the quality and origin of goods through the blockchain is crucial.In this paper,we study a cooperative supply chain composed of multinational enterprises located in high tax countries and e-retailers who purchase and resell goods from multinational enterprises.E-retailers compete with the retail departments of multinational enterprises in low tax countries.First,we study the optimal decisions of risk averse cross-border supply chain members under the static environment of random demand,and then introduce the time factor,Based on the dynamic change of blockchain technology level,differential game is used to conduct dynamic coordination,build a dynamic model,analyze the decisions of different members when avoiding risks,and finally use cost sharing contract to coordinate supply chain members to maximize profits.The research shows that under static and dynamic environments,different supply chain entities’ risk aversion behaviors have different effects on the optimal decision of supply chain.The risk aversion behavior of transnational enterprises leads to the reduction of the application degree of blockchain technology,wholesale price,and sales price of electronic retailers and retail departments of transnational enterprises,but the risk aversion behavior of retailers will lead to the increase of wholesale price,and the reduction of the application degree of blockchain technology,and sales price of electronic retailers and retail departments of transnational enterprises.In addition,when multinational enterprises are risk averse,the investment in the block chain is the lowest,the decision-making is more conservative,and the wholesale price and the retail sales price of multinational enterprises are both the lowest.When the supply chain entities are risk averse and the cost sharing contract is used,the block chain has the highest investment effort and the supply chain has the highest utility.The contract can effectively coordinate the supply chain.In the dynamic environment,the application level of blockchain technology gradually increases over time and eventually tends to be stable,indicating that the blockchain technology investment is controllable,and multinational enterprises need to strengthen the control of blockchain technology investment.In addition,multinational enterprises are more willing to invest in blockchain technology when market competition becomes relaxed and tax differences decrease.
