Abstract: In order to ensure the healthy development of special equipment safety management, to promote the formation of a pluralistic governance pattern, this paper used the idea of cooperative game to research the distribution pattern of special equipment safety benefit. In this paper, through the establishment of special equipment GMDS governance subjects, building safety output models, safety input cost models and safety non-benefit models respectively, safety benefit models of GDMS subjects were obtained. Based on this, the Shapley value method was used to explore the safety benefit allocation function of each governance subject, and the allocation model was verified.The results show that the safety benefits obtained by diversification of the main cooperation in the management of special equipment are much higher than those obtained by the individual governance, and that the cooperative game can achieve the optimization of safety benefits and fairness, and thus arouse enthusiasm of the main subjects for the special equipment management.
