Research On Evolutionary Game Of Collaborative Innovation Network Of New Energy Vehicle Industry Under Different Dominant Roles

The development of new energy vehicle industry has been a significant strategic decision in China,and collaborative innovation network is an ideal carrier for strategic emerging industries such as new energy vehicle industry to realize innovation.The research shows that the network structure with dominant roles is more effective for the construction of innovation network.And the development history of China’s new energy vehicle industry is not long,the industrial data is incomplete,the stakeholders are still in the game exploration stage.Based on the evolutionary game theory and combined with the quantitative research of software simulation,according to the train of thought of "Theoretical proposal-Network analysis-Establishment of evolutionary game model-Numerical simulation-Countermeasures and suggestions",this paper studies the evolution law of collaborative innovation network’s cooperation relationship of new energy vehicle industry under different dominant roles,attempts to find the path to realize the stable evolution of cooperative relationship under different dominant roles,the dominant roles state to more efficiently realize the stability of the network,and put forward countermeasures and suggestions for the optimization of the network from the perspective of dominant roles.Firstly,this paper summarizes the relevant literature research;analyzes the concept related to this research;discusses the characteristics,elements,structure,cooperation map and dominant roles of the collaborative innovation network of new energy vehicle industry,divides the dominant roles in the network into without dominant roles,the dominant roles of government and the dominant roles of core enterprises,lays a foundation for the research under different dominant roles.Secondly,separately establish the evolutionary game models without dominant roles,under the dominant roles of government,under the dominant roles of core enterprises,using evolutionary game theory to explore the local stability of the network.Thirdly,in order to better simulate the situation in the game model and the distribution law of the evolutionary stability strategy in the real situation and the evolution law of the network under the changes of dominant roles,combined with the evolutionary game theory and computer simulation technology,construct the network evolution algorithm without dominant roles,under the dominant roles of government,under the dominant roles of core enterprises separately to simulate the evolution process of the network.Finally,based on the above research,this paper further puts forward countermeasures and suggestions for the optimization of the network under different dominant roles,provides a new idea for the practical development of collaborative innovation network in new energy vehicle industry.
