Identification And Sharing Of Shared Risks Of Quasi Operational Projects Under PPP Mode

PPP(public-private-partnership),as a financing mode to improve the supply mechanism of Public services,can not only effectively relieve the pressure of government fiscal expenditure,but also promote the construction of infrastructure in China.PPP mode relatively insufficient prospective business project with large investment,economy and income to cover costs,in the long concession period inevitably there are all kinds of risks,including sole risk and risk,because the government and social capital interests differences exist,leading to the management of the risk in tend to be concentrated area of conflict.In order to improve the relationship between participants and promote the sustainable development of the project,reasonable and effective risk sharing is the key problem to be solved.In this paper,the PPP mode quasi operational risk in project as the research object,on the information asymmetry theory,contract theory,game theory,social choice theory as the theoretical support,in order to reduce conflict between parties,fair and reasonable share the risk for the guidelines,to sustainable development of the project smoothly and study for the final purpose.Firstly,through case study and literature review,the co-undertaking risk identification is carried out to obtain the list of co-undertaking risk factors for quasi-business projects in PPP mode.In combination with the characteristics of co-undertaking risk,the logic relationship between co-undertaking risk factors is discussed by using the interpretive structure model.Then,the network analytic hierarchy process(ahp)and grey cluster evaluation method areused to construct the evaluation model of the co-risk of quasi-business projects under the PPP model,to determine the weight of the co-risk and its importance.Then,through the analysis of risk is important to coordinate the contradictions and social choice theory to undertake to assume the standard to determine responsibility for the participants,and thus build random cooperative game model between the government and social capital,from the perspective of cognitive-control-willingness to establish model of the index system and to determine the index weights,the formation of ANP-important risk in Shapley value allocation model;Finally,relevant data of a PPP project of kitchen waste treatment in a city are selected for case analysis,which is compared with the actual situation to verify the rationality and feasibility of the model.Fair and reasonable risk sharing scheme is the prerequisite of participants and orderly cooperation,the PPP mode quasi operational project risk allocation model building,not only for the parties to provide a basis for the reasonable risk sharing and the new way of thinking,but also can effectively reduce the conflicts between the government and social capital,improve the efficiency of negotiations on the risk sharing between parties,so as to promote the vigorous development of the PPP project.
