Design And Implementation Of PPP Project Financial Evaluation System

PPP project is a long-term cooperative relationship between government and social capitalists in infrastructure construction and public services.The main characteristics of PPP project are long cooperation cycle,high investment cost and high potential risk.At present,there is no unified PPP project financial evaluation system in China.Some enterprises used Excel platform for PPP project financial evaluation.With the increase of PPP project year by year,it is urgent to establish a PPP project financial evaluation system for reference of government and social investors.It can reduce economic risks of project,improve the effectiveness of project financial evaluation and improve success rate of project.PPP project rely on national taxation,bank interest rates,etc.for investment,financing,lending and other economic activities.It relies on government and user fees to make profits.Since PPP project usually have more participants and complex financial management,it is necessary to establish a rigorous calculation system to judge the financial profitability of the project.The calculation system judges the financial profitability of the project by calculating the core financial evaluation indicators such as static payback period,dynamic payback period,internal rate of return,financial net present value and so on.Firstly,this paper points out the necessity of constructing a financial evaluation system for PPP projects,and analyzes the key technologies in system design based on this.Secondly,the financial evaluation process of PPP project is analyzed,and the relevant evaluation indicators are analyzed and calculated.Then,taking the traditional Excel platform for PPP project financial evaluation system as an example,this paper analyses the problems of complex calculation and difficult management.Four functional modules were designed according to the demand analysis,including system structure,basic settings,project management and project bidding compilation.Four functional modules,system architecture and database were designed in detail,and PPP project financial evaluation system was realized.Finally,the financial profitability of PPP project was analyzed through case study on the basis of system implementation.The changes of core financial evaluation indicators such as static payback period,dynamic payback period,financial net present value and internal rate of return with the construction investment cost tax rate and project capital ratio are obtained.The change rule of core financial evaluation indicators with the loan repayment mode and the proportion of project capital was obtained.The core financial evaluation indicators include static payback period,dynamic payback period,financial net present value and internal rate of return.Practice showed that the PPP project financial evaluation system was developed by Visual.Net Studio + ExtJS technology and MVC three-tier architecture model.The system can not only quickly and accurately calculate the financial evaluation datas such as the project investment recovery period,but also analyze and analyze the key factors affecting the evaluation indicators from a microscopic perspective to determine the project's profitability.The system can also flexibly solve problems when PPP project finance is dealed with Excel,such as unable to share data,numerous calculations,and complex operation of financial evaluation process.
