Computational Experimental Study Of Benefit Modulation Of PPP Projects Based On Value Network

Public-Private Partnership(PPP)is an innovative approach for providing social products or services.It introduces social capital into the public service field,exerts the market competition to optimizes the efficiency of public goods supply which improves the public's living standards.Under the background of rapid urbanization in China,a large capital demand in infrastructure investment,the PPP model has achieved unprecedented development opportunities.The year of 2014 is the beginning of the rapid development of PPP in China why it can be called the “first year” of the official development of PPP.After that,the PPP project has increased rapidly.The construction period of a PPP project is as short as 1 to 2 years and not more than 3 years,which means A large number of PPP projects have entered or are about to enter the operation period.Although many scholars have already studied PPP income from the perspectives of PPP project income formation,income risk,and income distribution,compare to the complex dynamic changes in the full life cycle of the PPP project are still insufficient.The urgent need of PPP project practice and the lag of theoretical research highlight the significance of this research.(1)Literature review and technical route.By summarizing the related research on the distribution of the PPP project income,the basic connotation of the PPP project income was analyzed.Based on the research at home and abroad,the research objectives are clarified,and the research ideas and technical routes were clearly designed.(2)Theory and method elaboration.Through literature review,the related concepts of stakeholder theory,value management theory and game theory were summarized and introduced.And related applications were sorted out,which lays a solid foundation for model establishment,parameter selection and theoretical derivation of this study.(3)The PPP project value network establishment.Through the analysis of the PPP project stakeholders,the position of each stakeholder in the PPP project was clarified,the value input(value needs)and value output of different PPP project stakeholders were analyzed,after that the PPP project stakeholder value model has been proposed.Further,the value flows between stakeholders were matched,and the value formation process of PPP projects was sorted out.Based on this,the PPP project value network was proposed.(4)Game theory analysis of PPP income adjustment.The characteristics of the PPP project income distribution and the decision-making mechanism of stakeholders were analyzed.With the relevant theory of cooperative game,an appropriate game model was selected On this PPP project income game basis model,considering the relevant factors of PPP project stakeholders,the former game model of the PPP project income distribution was constructed.(5)The PPP project income adjustment model.From the perspectives of system construction and PPP project income formation,the PPP project income adjustment model was structurally decomposed,and the idea of the model was designed accordingly.Throughout the analysis of the financial factors of PPP project,the influence factors of stakeholder satisfaction and the PPP project income adjustment measures,the PPP income adjustment theory model was established based on value network theory and game theory.(6)Establishment of PPP Project Income Adjustment Computing Experimental Platform.Based on the PPP project income adjustment theory model,the System dynamics and MAS(Multi-Agent Simulation)modeling method were used to found an experimental platform for PPP project income adjustment computational experiment.Based on the case financial and environment data,the project was analyzed in depth in the calculation experiment platform.Based on the experimental basis,the computational experiment of the PPP project income adjustment measures was carried out,and its action law was further explored and putting forward corresponding enlightenment and suggestion.
