Risk Research Of Public Utility Project Based On The Model Of Public Private Partnerships

In recent years, there are enormous fund shortfalls in the infrastructure construction of our country, national budgetary investment is too inadequate to afford greater pressure of infrastructure investment; On the other hand, private economy, whose strength is powerful, has the strong wishes to invest into the infrastructure construction. Then, PPP(Public-Private Partnerships)emerges with the tide of the times. Compared with other financing model, its scope of application is wider and its advantage is more obvious.At first, this paper studied the definition: of the PPP model, explores its theory background, birth background, and its application abroad. Then suitable forms of PPP model of our country, the participants' contract relationships, and the operation procedure of PPP model has been discussed in details.Based on analyzing the characteristics of the public utilities project and the mode of Public Private Partnerships(PPP), this paper has analyzed the characteristic of the project risk identification of public utilities based on PPP, has identified the project risk factor of public utilities based on PPP, including environmental risk, financial risks, technological risk, market risk, management risk and force Majuro risk.Risk allocation is crucial to the success PPP project. In chapter 4, this paper has done concentrated research to this question. On the basis of case analyzing and under the help of expert panel, this paper has set up a risk evaluation index system based on participants, and has set up a risk evaluation model with the Analytical Hierarchy Process. Whether the risk evaluation model is effective or not, a key factor is the rational proportion of the risk factor. This paper introduces the thought of clustering analysis, take advantage of Euclidean Distance and Correlation Coefficient to describe the similar degree of risk factor's proportion made by experts, and then the goal of optimizing proportion has been achieved.In addition we can through increase project risk managerial ability, merit of project manager, reduce or remit the risk factor too. At last, the paper makes real example analysis to the Shenyang Hunnan sewage disposal project, in addition to confirming the evaluation result is objective and reasonable, this analysis has also offered a valuable reference material to the application of PPP model in infrastructure construction in our country.
