Abstract:Considering the complex interaction network, as well as the competition and cooperation between enterprises, we construct the industrial innovation cluster model by using the particle swarm optimization algorithm. Some factors are studied, like enterprise competition radius and network degree. This study aims at promoting formation and development of industry innovation cluster. Results show that, cooperative innovation is the key factor to break the bottleneck for enhancing industrial development scale. Larger radius of competition produces positive influence on scale and geographical concentration of industry innovation agglomeration, and it has negative influence on the maximum of market concentration. Larger degree of cooperate network, to some extents, can improve speed of development and speed of spatial agglomeration of industrial innovation cluster.
