Research On The Risk Reallocation Proportion Of PPP Project Based On Bargaining Game

The long duration of the PPP project and the incompleteness of the initial franchise contracts between the two parties make it difficult to prevent all the risks in the construction and operation of the project.Therefore,during the construction and operation of the PPP project,government departments and the private sector The actual situation of the project The initial contract risk-sharing program to re-adjust,through the risk re-sharing to promote the smooth progress of the project and effectively protect the interests of stakeholders.We first construct a redistribution risk checklist by combining literature research with case study,then combine the incomplete information theory,the incomplete contract theory and the bargain game theory to analyze the applicability of PPP project risk reassignment,The bargaining model of the PPP project risk reallocution,the hypothesis and parameters of the model,and the bargaining game model of the government first bids and the private sector first bids were constructed respectively.The model was solved and analyzed,and the government and the private sector Calculation formula of risk redistribution proportion of PPP project.Finally,a case study was carried out on an industrial park sewage treatment plant project in Tianjin.The survey questionnaire was distributed to the experts through the expert survey method,and then the adjustment questionnaire was further analyzed and analyzed.The model parameters were obtained and the model was obtained.In the case of private sector in the proportion of risk re-sharing,through case verification found that the private sector to use their risk re-sharing in the strong position and information advantage in the risk of re-sharing of government departments to transfer the risk of government departments through the first risk-sharing To a certain extent,improve the risk re-sharing in the unfavorable situation.In this text,the bargaining game theory is used to study the risk reallocation of PPP project.Theoretically,the game model of PPP project risk-sharing is expanded.In practice,it also distributes the risk-sharing share of PPP project scientifically.The basis for decision-making,an increase of PPP project risk re-sharing of scientific.
