Knowledge Diffusion Performance Of Cluster Innovation Network

Clustering innovation network is a self-organization of the internal body in order to adapt to the complexity of innovation.The structure of cluster innovation network determines the function of network,which affects the performance of knowledge flow and knowledge diffusion between cluster owners.In this paper,the virtual simulation method is used to study the influence of the topology of cluster innovation network on the performance of network knowledge diffusion.Specifically,the network evolution model and the knowledge diffusion mechanism of cluster innovation network are constructed according to the characteristics of cluster innovation network.Based on the theory of complex network,this paper firstly analyzes the dynamic evolution of cluster innovation network and establish a network evolution model by taking into account the regional cluster characteristics of cluster network and the bidirectional selectivity of cooperative relationship as well as the occupancy of cooperative resources.By running the evolution of the model,the network topology of the cluster innovation network could be obtained.From the evolution of the network topology,we can get the network of cooperative networks.On this basis,the relationship between the knowledge diffusion performance and the innovation cooperation subject is analyzed,by building the knowledge diffusion mechanism which considers the global diffusion effect of knowledge diffusion.Then we take advantage of network average knowledge level,knowledge growth rate,individual knowledge difference coefficient and knowledge spatial distribution coefficient to evaluate the performance of knowledge diffusion.On the other hand,this paper analyzes the cluster innovation from the topological perspective based on the network topology evolved by running different parameters.Based on the corresponding numerical analysis results,the relevant conclusions are put forward to improve the performance of knowledge diffusion.Finally,this paper uses the new energy vehicle cluster innovation network in the three provinces of Northeast China as a case to research the evolution process of the knowledge diffusion.According to the numerical results of the simulation,several optimization suggestions are proposed.
