Research On Risk Evaluation Of Sponge Urban Construction Project Based On PPP Model

The construction of sponge city is a new type of rainwater management model which is put forward in accordance with the development trend of the country.China was originally proposed in April 2012,and after the year,because of the strong support of the country,the first batch of "sponge city" Project promulgated.The construction of sponge city is mainly to solve the problem of waterlogging in many cities in our country,and can realize the effective utilization of water resources,which is of great significance to the construction of ecological civilization in our country.China's sponge city construction project is the most commonly used form of PPP mode,because the PPP project and sponge city construction projects are similar,can be well together.PPP projects and sponge city construction projects are still in the initial stage,so the two types of project risk management research results are relatively small,and these two forms of PPP model of the sponge city construction project risk management research results It is rare,and these results are mostly on the theory,technology,planning and design research,the relevant risk management research results are almost no,so the PPP model of the sponge city construction project risk assessment to fill this gap,Has a significant guiding significance.The first chapter analyzes the background and significance of risk assessment of the model of sponge city construction in PPP mode,and analyzes the current situation of risk management research of sponge city construction project in PPP mode at home and abroad in recent years.Research content and research methods.The second chapter is mainly about the PPP model of the sponge city construction project risk assessment research related to the theoretical review.And provide the theoretical basis for the follow-up index system and evaluation model of risk assessment.The third chapter mainly identifies the risk of construction project of Zhenjiang sponge city.In order to summarize the scientific and accurate list of risk identification of sponge city construction project in Zhenjiang City,the risk of the sponge city construction project of PPP model is defined first,then the commonly used risk identification method is compared,and the final application of literature analysis method and questionnaire survey method The risk identification identifies an accurate and reliable list of risk identification.The fourth chapter mainly carries on the risk evaluation to Zhenjiang sponge city construction project.Firstly,the commonly used risk evaluation method is listed and the final selection analytic hierarchy process(AHP)is used as the method of risk assessment for the sponge city construction project of PPP mode.Then,the risk identification index system of the sponge city construction project of PPP model was established by screening andintegrating the risk identification list of Chapter 3.Finally,the risk assessment model of sponge city construction project with scientific and reasonable PPP model is established and the risk assessment model of Zhenjiang Sponge City Construction Project is validated,which proves the scientificity and correctness of the model.Chapter 5 is the conclusion and prospect of the article.This paper establishes a risk evaluation system of sponge city construction project with perfect and reasonable PPP model,and establishes the risk assessment model of sponge city construction project with PPP model,and carries out risk identification and identification of sponge city construction project in Zhenjiang City.Risk assessment,to find the current impact on the construction of Zhenjiang City sponge city construction of the more significant risk factors in the future construction process only need to take reasonable measures to correctly deal with these risk factors can reduce or avoid these risk factors impact on the project,Which can be used for reference to the risk assessment of similar projects.
