In order to promote the interest coordination between the government and social capital side in PPP projects of the water park, and ensure the smooth construction and operation of the project, the behavior strategy of the two sides is carried out for the first time, and the government roles of both the macro manager and the micro participant of the project are considered in the game analysis. Static game is adopted to explore the Nash equilibrium between the government and social capital, while the evolutionary game model is constructed to dynamically analyze their behavioral strategies with the simulation process. It is concluded that when the risk cost of the government taking the inactive strategy is greater than the cost of the active strategy, and the risk cost of the social capital taking the speculative strategy is greater than the cost of the effort strategy, (active, effort) is the equilibrium strategy in both static and dynamic games. Otherwise, aiming to realize the equilibrium (active, effort) strategy, it is necessary to ensure that the government's social and ecological benefits should be much larger than the viability gap funding, and for the social capital side, the sum of additional benefits like brand effect, social influence and government rewards, and the viability gap funding, should be much larger than the benefits gained by switching to other business fields. Afterwards, the corresponding countermeasures are put forward, including improving the benefit distribution, risk sharing and policy guarantee mechanism of PPP projects in water park, establishing communication mechanism between the government and social capital side, and strengthening the supervision of PPP projects in water park.
