Performance Assessment Of Urban Water Environment Treatment PPP Project

The construction and operation of urban water environment treatment PPP project are generally completed by cooperation between government and private sectors,which mainly use the performance-based payment by government.Since the operation period over ten or twenty years,the result of performance assessment is basic to payment,and the scientific and reasonable evaluation index system is one of the key factors affecting it.Efficient and reasonable performance assessment for the supervise the operation period of PPP project is the guarantee of realizing social benefits and enhancing the sustainable development.Urban water environment treatment PPP project,which is obtained through introducing PPP model into urban water environment treatment project,is characterized by complicated project structure and lots of affecting factors.And there are many difficulties to conduct performance assessment for urban water environment treatment PPP project.How to evaluate the performance of project appropriately,how the public are invited to join in the project performance assessment more effectively,how to carry out the evaluation from third party for increasing efficiency of performance assessment in the project operation period,how to construct evaluation model for performance assessment,are the eager to solve issues of urban water environment treatment PPP project.Therefore,conducting performance assessment for urban water environment treatment project has the important research significance from theory and practice.Based on the literature and the characteristics of urban water environment treatment PPP project,the research is conducted in the field of theory and practice.Firstly,based on the water ecology,water resources,water engineering,water landscape and water management,the index system consisted of the hydraulic structures,river water,landscape facilities,landscape plants,bridges,public satisfaction is constructed by combining the questionnaire survey and expert interview methods from the aspect of water infrastructure,landscape engineering,municipal engineering,river water body and public satisfaction.Secondly,according to the characteristics of multi-source appraising subject and diversity evaluation index,a group evaluation cloud model combined by group evaluation and cloud theories is developed.The role of multi-source appraising subject is expressed by group evaluation,and the cloud model is one for transformation between qualitative and quantitative knowledge from different indexes.Thirdly,for the third-party evaluation mechanism,because of the PPP third-party performance assessment laws inadequate,third-party performance assessment mechanism of urban water environment treatment PPP project is designed on the basis of the research in this field from the developed countries.And the process of implement performance evaluation is set by the practical operation of urban water environment treatment PPP project.Finally,the evaluation assessment result is analyzed using an example.In empirical research,urban water environment treatment PPP project in Xuchang City is applied to illustrate the effectiveness and practicability of proposed theories.From the analysis of the characteristics of each dimension data,the cloud grades from SPV corporation,river embankment,hydraulic structures,river water,landscape facilities,landscape plants,bridges and public satisfaction are all ?good?,and the whole evaluation is also ?good?.This result is the same as the actual result of urban water environment treatment PPP project in Xuchang City.
