Evolutionary Game of Supply Chain Alliance Based on Blockchain

The combination of blockchain and supply chain is conducive to building a trusted and shared alliance environment. This paper discusses the evolution direction of alliance members in a supply chain under the environment of blockchain network. Income matrix is firstly established and then dynamic equation is obtained. Based on dynamic equation, equilibrium points and Jacobian matrix are derived. Through analyzing the sign of determinant and trace of Jacobian matrix, the stability of equilibrium point is studied. Further, the simulation presents the evolution trajectories of alliance members under different situations. The experimental results show that blockchain has a positive effect on the choice of the strategy and on evolution speed of the alliance. The work will help to develop a supply chain alliance relationship that features openness, sharing, credibility and win-win cooperation.
