Abstract Considering the high concentration, scale-free and “community structure” of social networks, according to “Prisoner's Dilemma” game, we establish an evolutionary game model for complex social networks based on multi-preferences, apply the node influence to the rule of game strategy update innovatively, and use Matlab platform to simulate. Besides, we analyze the multi-preferences, “community structure” and inter-community links to reveal the influence and inherent mechanism of cooperative emergence in social networks systematically from both macroscopic and microcosmic perspective through contrast simulation experiments. It is shown that community structure characteristic under multi-preferences affects the heterogeneous expectation level of agents; “community structure” can promote the emergence of cooperation; the influence of inter-community links to cooperative emergence has a relation with community scale.
