Research On Game Equilibrium And Income Distribution Of Supply Chain Finance In The Context Of Blockchain

The rise and development of supply chain finance have to some extent solved the problems of difficult and expensive financing for small and medium-sized enterprises.In recent years,its scale of development has grown stronger.However,in the financing process of supply chain finance,there are such things as information islands,data fragmentation,and financing cannot run through all small and medium-sized enterprises in the chain,and the risks of keep the appointment are difficult to control effectively,which greatly hinders the development of supply chain finance.The advent of blockchain technology provides new ideas for the financing dilemma of supply chain finance.Its unique characteristics such as asymmetric encryption,distributed ledgers,decentralization,and smart contracts have been favored by the financial field.The integrated study of the two is now a research hotspot in the financial field.At present,most of the research on the combination of the two is described from a qualitative perspective,so it is urgent to use quantitative model methods to conduct in-depth research on supply chain financial financing in the context of blockchain.From the perspective of the financing process of the supply chain financial alliance and the distribution of the alliance's income,this article mainly discusses the game equilibrium of the participants and the income distribution of the parties in the supply chain financial financing business under the blockchain background.The key research content includes the following three respects.(1)Research on the impact of blockchain technology on supply chain financial services and whether the technology can improve the supply chain financial services.First,analyzing the incentive effect of blockchain technology on the banks,small and medium-sized enterprises and core enterprises that as main participants in the supply chain financial financing process,and exploring the influence of the characteristics of blockchain technology on the model of supply chain financial financing,then giving the corresponding financing model diagram,which clarifies the promoting role of blockchain in the supply chain financial financing business.(2)Research on the game equilibrium of supply chain financial financing under the background of blockchain.Taking the account receivable financing model of supply chain finance as an example,establishing a game model which is mainly constitute of banks,small and medium-sized enterprises and core enterprises in the financing process,and using the expected return method to obtain the Nash equilibrium of supply chain finance based on the assumption of rational people,and comparatively analyzing the game equilibrium point of the traditional supply chain finance and the supply chain finance under the background of the blockchain.(3)Research on the income distribution strategy of the equilibrium point of the financial game of the supply chain under the background of the blockchain.At the point of game equilibrium,firstly,the thesis explores the influencing factors of the income distribution of the participants in supply chain finance under the context of blockchain,and uses the gray correlation method improved by interval numbers to determine the weights.Then in the income distribution method,considering the fuzzy income value of the financing alliance and in the traditional interval Shapley value method,the income distribution does not consider the different degree of contribution of each participant to the alliance.The thesis introduces interval intuitionistic fuzzy numbers and applies interval intuitionistic fuzzy TOPSIS method to modify the coefficient of interval Shapley value income distribution,forming an improved interval Shapley value method.The final case analysis proves the feasibility of the income distribution plan proposed in the thesis.
