Abstract:In order to study the technology collaborative innovation strategy of marine ranching enterprises from the perspective of prospect theory, this paper constructs a tripartite evolutionary game model of "government - marine ranching enterprises - academic and research parties" based on the perspective of prospect theory, analyzes the stability of the evolutionary strategy of the system, and analyses the government"s regulatory cost and intensity, the central government"s punishment, and the government"s influence on enterprises and academic and research parties. The results show that the government, marine ranching enterprises and academic and research parties have the right to participate in the game. The results show that the decision making behaviour of the government, marine ranching enterprises and researchers is influenced by the decisions of the other two types of participants; the penalties imposed by the central government and the cost and intensity of regulation by local governments affect the choice of the government"s own behaviour to a certain extent; the incentives provided by the government to marine ranching enterprises and researchers can promote the choice of collaborative innovation strategies, but the government"s incentives need to be within the government"s affordability. However, government incentives need to be within the government"s affordability; the choice of strategies by marine ranching enterprises and academics is influenced by the apportionment factor.
