Abstract: With the network development of cooperation innovation, the profit demand of every subject in the innovation network has exerted a more and more significant impact on the network evolution. Based on the influence of various profit distributions upon subjects’ cooperation behaviors in the innovation network under different network topologies, the game model of network evolution is established. Combined with many factors such as reputation mechanism, learning behavior and network environment, it carries through a simulation research on the evolution of innovation network’s cooperation behavior in scale-free networks and small-world networks. The research results are as follows. First, the evolution of innovation network’s cooperation behavior is subject to the dual influences of network structures and its scales. Cooperation expressions are the most stable under the scale-free networks. Second, the distribution of cooperation benefits produces an effect on the evolution of innovation network’s cooperation behavior. At last, temptation of opportunity benefits brings about the fluctuation of innovation network’s cooperation behavior.
