Abstract:The analysis of the decision-making behavior of participants in the supervision of block chain information service helps to find the balance between block chain innovation and supervision. Based on the evolutionary game theory of finite rationality, a tripartite evolutionary game model of block chain information service supervision is established. By analyzing the evolutionary stability of game strategies of government departments, information service providers and users, and incorporating the idea of “scenario-response” into the calculation experiment method, numerical simulation and simulation calculation are carried out. Experimental results show that in government regulation scenario, through “command – control” mechanism to avoid the risk of illegal information service, often because of difficult to control and hinder block chain innovation and development, and establish the information service of supply and demand both sides “losses – compensation” dynamic debugging supervision regulation, can improve the use efficiency of the information service.
