Research On Risk Sharing Method Of Public-Private Partnership Project Based On Uncooperative Game Theory

Because of the PPP project is able to provide the benefit-sharing,risk-sharing partnership for government and private investors,it has become a new model of society to provide public products and services and to ease government debt crisis in recent years.However the complexity of the PPP project itself inevitably lead to risk factors throughout the entire life cycle of the project.Ignoring the existence of risk typically consume large amounts of time and cost,so the risk sharing problems is key point in the research of the PPP project.Reasonable risk sharing scheme can usually guarantee the successful implement of the PPP projects,Using the game model twice in this paper,aims to put forward a kind of participants could easily understand and accept risk sharing method.First of all,regard the PPP project of government and private investors as stakeholders,according to game theory,on the basis of risk appetite divide into risk borne by the stakeholders alone and needs of stakeholders share the risk,the former kind of risk in accordance with the risk bearing capacity allocated to each stakeholder.Second,the share of risk on the remaining problem is transformed into stakeholders under the cooperative relationship between the risk of game,in the original bargaining model,on the basis of considering the main influence game decision-making risk of loss in the process of transfer factor and bargaining negotiations,the model was improved,and share schemes have its validity.Thirdly,at any time during the implementation process,the unrecognized risks are evaluated and the proportion of unreasonable share can be adjusted,the risk sharing guarantee system is constructed to form a complete risk sharing scheme for PPP projects.Last,for example,Shandong University of Finance and Economics PPP project laiwu campus construction is the first PPP project in Shandong province.The use of the optimized allocation proportion,risk sharing scheme design verification results conform to the PPP project risk Shared between the government and the private sector,proved that the model is feasible.
