Abstract In this paper, we present an innovation diffusion model based on the local interaction and global broadcasting, which considers both the interaction between each node and the influence of the public media during the innovation spreading process. The experimental results show that as the effect of the global broadcasting is limited, the local interaction relationships would play an important role in the innovation diffusion. Furthermore, the simulation results on for real networks show that under the limited influence of public media, the improved method which integrates the network structure and innovation diffusion process can evaluate the node influence in innovation diffusion accurately. Comparing with degree, closeness and K-shell method, the largest improved ratio could reach 39.19%, 35.61% and 33.03% respectively.
