Research On PPP Project Risk Control

The rapid development of road traffic has greatly facilitated people's travel,but also brought increasing traffic pressure.All kinds of traffic accidents and the situation are uncommon,bringing many troubles to people's routine travel.In order to improve this situation,all the cities in our country have taken such measures as developing rail transit to cope with the huge traffic pressure.However,there are also many problems to be solved,just as other municipal infrastructure projects,the construction of rail transit on the one hand,a longer cycle,on the other hand requires huge construction funds,so the major cities have proposed rail transit is more suitable Short-term "sustainable development concept." As a result,the PPP financing model has also become a popular choice.This model is more flexible and efficient for the use of funds and can effectively solve the problem of funding rail transit.However,running PPP projects requires huge amounts of money and a long construction period.In addition,there are many risk factors for the PPP project with many participants and their respective interests.Therefore,in order to promote the success of this project,all parties Reasonable and efficient sharing of shares has become the key issue to be solved.After grasping the current research status both at home and abroad and mastering relevant theories,this paper applies the theory to the actual case analysis and takes Kunming Metro Line 4 as the analysis object,and introduces its construction background,implementation plan,main participants,relevant mechanisms and The progress of project implementation,followed by the public capital perspective,in-depth analysis of the rights and obligations exist in this case,the type of risk and risk sharing programs.Then,based on the public capital perspective,we use the game theory to deduce the risk sharing principle and then introduce Kunming Metro Line 4 as a case to find out the optimal risk sharing plan.After the analysis of this paper we can conclude that from the perspective of public capital,the risk sharing scheme of Kunming Subway Line 4 meets the principle of optimal risk sharing.On the one hand,Kunming Subway Line 4 runs well,In line with the initial expectations,effective risk control has been achieved;on the other hand,there are still some risk-sharing designs that need to be adjusted.
