Due to the impact of the characters of nodes in complex network on collaboration level, we put forward a new iterated game model based on conformist mechanism. In this model, nodes can update tactic not only according to their payoffs but also to their species, which they belong to. The new model can assure that nodes in the same species adopt the same tactic. Simulation results show that the collaboration level of the networks that adopt conformist mechanism is higher than the networks that adopt normal mechanism. In the other words, the collaboration level is in inverse proportion to the species number. On the other hand, we find that the average payoffs increased with the penalty gene instead of increasing alternately. So the new model can promote the collaboration level and the average payoffs of the nodes in network at the same time.
