Research On Post - Evaluation Of Infrastructure Projects Under PPP Model

In recent years, the PPP mode began to promote the investment and financing problems in the infrastructure projects in China, but because of the implementation of the PPP project of long duration, involving a wide range of investment, a long period of time of construction and operation and a great risk in late management, therefore, the infrastructure projects in PPP mode is very necessary.First, this paper describes the relevant concepts, and found that the PPP mode of the main operation process included the project plan, select the private investors, signed a concession agreement, project construction, project operation and project transfer, etc., and there were some evaluation methods in the infrastructure projects of the PPP mode,such as the process of building a project evaluation, evaluation of construction projects, construction projects, the impact assessment. And then, after the establishment of the PPP model, the post evaluation model of the infrastructure project is divided into three main aspects: the plan which based on evaluation, the evaluation of stakeholder satisfaction and the evaluation based on financial financing. In the planning index, the evaluation of the main statistical T test was used to test the indexes in the actual difference between evaluation value and planning, to understand the development of the project after the actual operation situation; In the stakeholders’ satisfaction assessment, in order to determine satisfaction with relevant personnel to the project and make sure the project can bring social welfare, mainly adopted the form of questionnaire, the related personnel to take sample survey; In financial financing, the evaluation of the main financial indicators of case project and financing index difference before and after the calculation, so as to get the actual parameter values prior budget and deserve a difference, to determine the actual operations of the project. Finally, this paper with the example of Shenzhen Metro Line 4 demonstrates how to evaluate the infrastructure projects in PPP mode.This paper evaluates through the three aspects of the plan, satisfaction and financial financing, and found that the PPP model can improve the financing problem, the financing efficiency and promote the development of the project.
