基于五元联系数的水环境治理PPP项目可持续性评价

Integrated sustainability assessment of PPP projects for water environment treatment based on five-element connection number

随着我国环境治理力度的加大,水环境治理PPP项目在基础设施建设中占了相当大的比重。但是,由于缺乏系统的指标体系、评价方法和考核工具,很难从理论上评判我国的城市水环境现状以及治理后的可持续性。借助集对分析理论,构建了基于五元联系数的水环境治理PPP项目可持续性评价模型,并选取许昌市水环境治理PPP项目进行案例分析。结果表明:项目整体可持续性较强,并存在上升的趋势,但项目公司管理可持续性处于下降趋势,应重点关注。运用集对分析模型,不仅可以得出项目整体的可持续性及趋势,也可以得出各评价指标的趋势,为项目提高或保持其可持续决策提供了依据。

With the increase of environmental governance in China, PPP projects of water environment governance account for a large proportion in infrastructure construction. However, due to the lack of systematic index system, evaluation methods and assessment tools, it is difficult to theoretically evaluate the status quo of urban water environment and its sustainability after treatment in China. With the help of the theory of set pair analysis, the sustainability evaluation model for PPP projects of water environment treatments is established based on the fiveelement connection number, and the PPP project in Xuchang City is taken as the case study. The results show that the overall sustainability of the project is strong, and there is an upward trend, but the sustainable management of the project company is in a downward trend, to which attention should be paid. Using the set pair analysis model, the sustainability and trend of the whole project as well as the trend of each evaluation index can be obtained, which provides a basis for the project to improve or maintain its sustainable decision-making.
