Application Research Of PPP Mode In Urban Infrastructure Construction Process

In the past,when local governments were building urban infrastructure,they mostly cooperated with local financing platforms or banks in the city,mainly using loans and other means to prepare funds for urban infrastructure construction.Due to the long period of capital recovery for urban infrastructure construction,and even some projects have no capital gains,they need to be financed at the municipal level.With the accumulation of financial pressure over the years,the local government's dominant and implicit debts have remained high.The rise of the PPP model has introduced ample social capital into the construction of urban infrastructure,which not only solves the financial problems of the government-led urban infrastructure construction projects,but also gives the government a certain amount of energy and ability to repay past debts.Alleviate local government debt.Based on the theory of PPP model,this paper analyzes the mechanism of PPP mode in policy subjects,policy objects and policy environment,and then implements the tram project by using PPP mode in Tianshui City,an underdeveloped small and medium-sized city in the west.For example,in-depth research and analysis.Through the analysis of the current situation of Tianshui City's transportation,it proves the necessity of using PPP model for urban infrastructure construction,and combines the mechanism of PPP model in urban infrastructure construction to analyze the city's use of PPP model for urban infrastructure construction.Feasibility.Then combined with the relevant theory and research of PPP mode at home and abroad,through the analysis of actual cases,further absorb the experience and shortcomings of Tianshui City tram project,and then analyze the urban infrastructure of PPP mode from the aspects of system regulation,benefit distribution and project management risk.The problems existing in the construction process and the countermeasures and suggestions are pointed out.
