Analysis of the Choice of Return Mechanism of PPP Model in Rural Human Settlement Improvement under the Rural Revitalization Strategy: Research Based on the Perspective of Evolutionary Game

The improvement of rural human settlement environment is a significant direction of the rural revitalization strategy. Based on the finite rational evolutionary game theory, a cooperative behavior evolutionary game model of rural human settlement environment improvement PPP model with local government, social capital and rural residents as the main game players with the reward mechanism of Government Payment and one with the reward mechanism of Viability Gap Funding are constructed. Comparing the total project revenue of two reward mechanisms, the thesis will obtain the effects of choosing the reward mechanism of rural human settlement improvement PPP. Finally, available suggestions are made to the decision of the reward mechanism of PPP project about rural human settlement environment, thus promoting the application and development of PPP in rural environmental management and to promote sustainable improvement of rural habitat improvement.
