Research On Risk Management Of Agricultural Products Supply Chain Based On Blockchain Technology

The agricultural product supply chain is centered on the integration of the logistics,capital flow,and information flow involved in each link in the process of agricultural products from production to consumption by core enterprises,linking manufacturers,distributors,wholesalers,retailers,consumers and other parties into A network with overall functions.During the operation of the agricultural product supply chain,it is affected by factors such as external environment,industrial competition,information transmission efficiency and sharing,and the supply chain exhibits certain key issues such as fragility,volatility,and complexity.,The risk management of agricultural product supply chain came into being.Traditional agricultural product supply chain risk management involves four aspects: risk identification,risk evaluation,risk optimization and control.Traditional supply chain risk management cannot completely effectively solve the problems of supply chain information transmission,information security,and moral hazard in contract execution.For this reason,based on the research on the coupling of blockchain and supply chain,this article applies blockchain technology to the risk management of agricultural product supply chain,and has achieved the following research results:First,on the basis of combing domestic and foreign research documents,the connotation and composition of the blockchain are clarified,and the coupling relationship between the blockchain and the supply chain,the decentralization of blockchain technology,distributed information storage,and peer-to-peer information are analyzed.Asymmetric encryption and decryption and smart contract technology can effectively weaken the core enterprises in the traditional supply chain's monopoly on the supply chain,information asymmetry and information management cost pressure;the risk management role of the agricultural product supply chain under the blockchain technology can make The overall efficiency of the supply chain node enterprises is better than that of the traditional structure of the supply chain,and it can better solve the influence of risk factors such as information security,information sharing and information management in the supply chain,and realize the secondary value-added value of the information transmission process in the chain.Secondly,based on several common agricultural product supply chain structure models,combined with China's current international and domestic situations,it analyzed the risk factors of agricultural product supply chain,established a risk indicator system,and obtained the main risk weights of agricultural product supply chain risks through the analytic hierarchy process.It is concluded that the agricultural product supply chain is mainly affected by information risks,cooperation risks and political risks,and the application of blockchain technology can effectively solve the current supply chain's information risks and other factors.Thirdly,establish a three-level agricultural product supply chain structure model,combine the main risk indicators,analyze and study the profit function of the three-level supply chain game theory,and use the profit function indicator to reflect the analysis of the effect of the blockchain on the supply chain information risk management,through comparison The overall profit of each node and supply chain under the traditional supply chain model and blockchain technology has been improved.It is found that the overall supply chain and the profit of each node under the blockchain are better than the profit level of the traditional supply chain.Finally,combined with the technical characteristics of the blockchain,a case study was carried out with the pork supply chain as an example,and the problems of information risk management and efficiency improvement in the pork circulation process of the blockchain technology were analyzed,and the risks of the blockchain to the supply chain were revealed.The value of effective management,through the application of blockchain technology for supply chain risk management,has certain practical significance for promoting the integrated application and risk management of blockchain in multiple scenarios...
