Evaluation And Control Of Investment Risk In PPP Project Of Longsui Expressway

The economic development cannot be separated from the convenient conditions of rail transit,so the construction of comprehensive network transportation route is of great strategic significance for the realization of the economic situation of facility connection and road unblocked.However,expressway construction has the characteristics of large investment amount,long construction period,wide scope,many risk factors and complexity,etc.so it can no longer meet the requirements of expressway and other infrastructure only by relying on the power of the government.The introduction of PPP will provide new impetus for infrastructure construction.However,China has not yet formed a systematic expressway project development model,which is prone to risk,not only makes the project unable to be successfully“landed”,resulting in investment losses,more importantly,is a waste of social resources,restricting the high-quality and stable development of the economy.In view of the investment risk of Longsui expressway PPP project,this paper,from the perspective of social investors,Uses Delphi method and AHP to identify the investment risk factors in the project life cycle by stages,establishes the investment risk index identification system,and sorts the risk indexes in each stage.The grey comprehensive evaluation method based on whitening weight function is used to evaluate the risk index of investment,determine the degree of risk impact,and put forward Suggestions on risk prevention from the perspective of social investors.Research conclusion is as follows: Long Sui highway PPP project investment risk degree between degree of risk of medium and high degree of risk,slightly towards the risk degree of medium,the policy change risk,high risk and the cost of financing the construction safety risk,operating income,risk and risk of concession period to recover significantly higher risk than others.Puts forward to establish equitable risk allocation structure,establish a reasonable decision-making mechanism,circumvent the risk of interest rate volatility,to form clusters risk prevention and control system and establish risk early warning mechanism to strengthen supervision of the project life cycle investment risk and other risk control suggestions,in order to smoothly Long Sui highway PPP project investment project investment to provide the reference.This thesis has 8 charts,19 tables and 83 references.
