Sustainability Assessment Of Water Environmental Treatment PPP Projects

As one of the countries with severe water shortages,with the rapid development of economy and society,China’s water environment problems have become increasingly prominent.Water pollution not only restricts the high-quality development of social economy,but also threatens the public health.Therefore,it is urgent to strengthen water environment treatment.In the traditional environmental treatment model,the government is fully responsible for the costs and management of environmental treatment,leading not only to notable financial pressure but also challenging the government’s management ability.Water environment treatment projects involve social infrastructure projects,such as sewage treatment,ecological restoration,and landscape greening;such projects require professional knowledge,and thus,guaranteeing efficiency while completely depending on the government presents difficulty.Therefore,introducing public–private partnership(PPP)into water environment treatment has gradually become critical.On the one hand,it can alleviate the burden of public financial shortage and ensure the timely provision of needed infrastructure.On the other hand,a private sector with valuable business opportunities can use innovative technologies and advanced management skills to improve governance efficiency and enhance the effect of water environment treatment.However,as the participation of the private sector in PPP projects is profit-driven,it is easy to pay too much attention to the economic target of whether the project is profitable,while ignoring the impact of the project on the environmental protection,employee safety and welfare,social responsibility and other aspects.As sustainable development gradually becomes the development path that governments,organizations and industries are eager to follow,however,to make this concept a reality,it needs to be clear what kind of projects are sustainable.In order to solve these problems,this paper conducts research on the sustainability assessment of water environmental treatment PPP projects.The specific research content mainly includes the following three parts:(1)The design of sustainability assessment indicator system for water environmental treatment PPP projects.On the basis of literature research,this paper comprehensively considers the characteristics of water environmental treatment PPP projects,and preliminarily selects 36 factors affecting the sustainability of water environmental treatment PPP projects from five aspects of economy,society,resources and environment,engineering,and project management.SPSS 22.0 software is used to carry out exploratory factor analysis on the sustainable factors,and finally determined 5 common factors and 27 indicators.And AMOS 22.0 software is used to verify and further modify the measurement model of sustainability assessment for water environmental treatment PPP projects,and a relatively complete indicator system for sustainability assessment of water environmental treatment PPP projects is finally formed.(2)The construction of sustainability assessment model for water environment treatment PPP projects.The water environment treatment PPP projects involve a wide range,and there are many sustainable influence factors and most of them are qualitative indicators.Considering the ambiguity and the mutual influence relationship of the evaluation factors,through the comparative analysis of the evaluation methods,this paper uses the analytic network process method to determine the mutual influence weight of the indicators,and a fuzzy comprehensive evaluation method is introduced to establish a fuzzy comprehensive evaluation model for the sustainability of water environment treatment PPP projects based on the analytic network process.(3)The empirical analysis.In order to further verify the effectiveness of assessment model,this paper applies the constructed sustainability assessment model to water environment treatment and ecological restoration project in Xuchang city,and proposes corresponding improvement suggestions based on the assessment results.Based on the research of water environment treatment PPP project,this paper innovatively constructs the sustainability assessment indicator system of water environmental treatment PPP projects from five dimensions: economy,society,resources and environment,engineering,and project management.On this basis,a comprehensive evaluation model based on ANP-Fuzzy is constructed by considering the ambiguity and mutual influence of evaluation factors.The research results of this paper provide a scientific evaluation method for the research on the sustainability of water environment treatment PPP projects,which is conducive to the improvement of project decision-making level,and has important theoretical and practical significance for improving the current situation of water environment treatment in China,and promoting the high-quality development of water environment treatment PPP projects.
