Abstract: This paper proposes a dynamic social network model for the competition among three languages with agent based modeling method and social circles theory. The parameters of the topological structure of constructed social network are more close to the parameters of actual social network. The individual agents in the network can give space attribute and can describe mixed habitation in a region with different languages and separation habitation in individual area with a language, so the constructed social network is endowed with dynamic characteristics. Taking the competition among three languages as an example, this paper proposes a method that the competition among three languages is decomposed into three times of bilingual competition, and presents a universal complex agent network model for multi-lingual competition and policy intervention. The agents on the network represent the individual which has the function of learning and forgetting. And each agent can gain a second or third language to become bilingual or trilingual by learning and can forget to become monolingual or bilingual. The vertical transmission of language is taken into account. The simulating analysis of the proposed model shows that the system parameters of language status, the proportion of people of different languages, the proportion of mobile population, social radius, living space model and integrated control measures can affect the results of simulation. The simulation results show that the model is close to the actual society and provides the basis for multi-lingual competition.
