Research And Application Of Risk Assessment Of PPP Project In Drinking Water Project

Nowadays,the country's economy and society are constantly developing,people's living standards are constantly improving,and people's water demand and water quality requirements are greatly improved.At present,most of the drinking water projects in China are funded by the government,and the sources of funds are relatively single,leading to drinking water projects.There is a problem of insufficient construction funds.According to the stable demand of drinking water projects,relatively stable cash flow,flexible pricing mechanism and high market share,the state encourages the use of PPP mode to run drinking water projects,attracting social funds to participate in the construction and operation of drinking water.project.In order to solve the problem of construction funds,the introduction of professional management and operation companies to participate in project operation will bring tangible benefits to the sustainable and healthy development of the project.However,due to the long life cycle of the PPP project,the complicated and diversified operation process,and the blurred boundaries,there are many risks in using the PPP model to construct drinking water projects.Scholars in various fields have proposed risk assessment methods for PPP projects from different professional perspectives,but have not yet formed a unified and effective PPP project risk assessment system.How to effectively identify and assess project risks has become an urgent problem to be solved.On the basis of previous studies,this paper builds a risk assessment model based on fuzzy analytic hierarchy process based on the technical path,problem analysis,problem solving and practical application.In terms of theoretical research,this paper introduces the theoretical basis of drinking water engineering and PPP model,and studies the current situation and the development of drinking water engineering in China based on the risk assessment management process,grey system theory,analytic process and fuzzy mathematics.problem.In terms of methods and means,make full use of the convenience of work,select government officials and industry experts to collect and collect scores through questionnaires,classify and summarize them,and consult relevant documents based on aggregated data and current risks.China's assessment method.Improve and innovate to get the most intuitive help in project decisions.In the case study,the NM drinking water project PPP project was used for empirical analysis.Using the constructed risk indicator system and risk assessment model to assess project risk,the 6 risk weights of project risk are:financial risk>construction risk>operational risk>political risk>legal risk>force force majeure risk;financial risk,which is in the project The most prominent type of risk.The weight of possession is up to 0.4708.Construction risk is the most prominent type ? risk of the project,with a weight of 0.2464.The overall risk assessment of the project is 1.77,which belongs to the general risk category.Through analysis,project decision makers can more intuitively read reference data and make decisions.This dissertation provides a new idea for the risk assessment of PPP project construction in drinking water projects from the perspective of third parties,analyzes the origin of project risks,determines the weight of key risk factors,achieves project decision-making and promotion,and effective risk prevention measures to reduce or even eliminate risks.Adverse reactions have good theoretical and practical value.
