Abstract: The acceleration of the Arctic route navigation process increases the possibility of maritime incidents which directly threaten the Arctic marine environment. Such incidents definitely will arouse responses from the Arctic countries, observer-countries and other actors who claim to have interests in the Arctic region, all of whom thus form a giant and dynamic multiple-factor Arctic environmental governance response complex network. Based on complex network, public goods evolutionary game, simulation and other theoretical methods, this paper establishes an Arctic environmental governance evolutionary game model to study the cooperative behavior among the countries in the response complex network. It reaches a conclusion that the long-term benefits and return intensity affect the national revenue function directly in the network, which influences how a country acts on the Arctic environmental governance. The results can enrich related theoretical researches of Arctic governance, and provide reference for China's participation in the Arctic environmental governance and the relevant decision making.
