Abstract: By taking the local government, the management agencies of protected areas and the surrounding community residents as the main stakeholders of the community co-management in protected areas, and using the dynamic game model with complete information, the behavioral strategy selection of the stakeholders after the expiration of the community co-management project was analyzed. The results showed that the optimal equilibrium point of the game could be achieved if the local government would help the residents to develop alternative livelihoods, the community residents would consciously protect the ecological environment, and the management agencies of protected areas would actively carry out the supervision and establish the effective reward and punishment mechanism, which will be conducive to the sustainable development of protected areas.
