An Evolutionary Game Simulation on the Core Enterprise and Its Supporter in Collaborative Innovation

The Stackelberg game model is applied to analyze the collaborative innovation among the Core enterprise and Its Supporter and to calculate the optimal effort of supporting enterprises, based on which the payoff matrix of the core enterprise and its supporter is calculated. Then the influence of selection strategy of the core enterprise and its supporters with the third party intervention is studied. The evolutionary trace of the equilibrium point is proved by adopting a numerical simulation. The research shows that collaborative innovation is a win-win strategy, and that the two sides in the collaborative innovation achieve stable equilibrium when there is intervention of the third party in the clusters and the technology subsidies ratio of core enterprise and the risk supporting enterprise bears is equal. Finally, the corresponding countermeasures and suggestions are put forward.
