Partner Selection Model for Sewage Treatment PPP Projects to Meet Stakeholder Needs
Due to the fund shortage and the low efficiency in urban sewage treatment project in China, public private partnership (PPP) has been acknowledged by many as an innovative way to the supply of sewage treatment engineering. Stakeholders' satisfaction is a measure standard of the success of PPP projects, and partner selection is critical to the success of PPP projects. This paper proposes an integrated approach combining stakeholder theory, quality function deployment and fuzzy set method to establish a partner selection model for PPP projects to meet core stakeholders' needs. This model has identified the four core stakeholders and eight type needs in PPP projects, and has constructed the fuzzy relationship matrix between stakeholder needs and partner selection criteria and the fuzzy decision matrix for partner selection. Finally, the practicality and the effectiv

Determinants of public satisfaction with an Urban Water environment treatment PPP project in Xuchang, China
Abstract City dwellers are critical stakeholders in the case of urban water environment treatment Public Private Partnership projects (UWETP PPP) This type of partnership is increasingly popular in China. Accordingly, public satisfaction should be considered in any performance evaluation of such a partnership. However, little attention has been paid to identify factors that affect public satisfaction with UWETP PPP in scholarly studies. To address this gap, this case study aims to apply structural equation modeling (SEM) to explain and identify the determinants of public satisfaction with UWETP PPP in Xuchang, China. Furthermore, the findings from this case study are intended to inform the development of more effective management strategies for a special purpose vehicle (SPV) using importance performance analysis (IPA) A total of 240 questionnaires on public satisfaction were collected through the case of the water environment treatment and ecological restoration project in Xuchang, China. This paper firstly employs exploratory factor analysis to extract 6 primary factors from 33 preliminary indicators that affect the public satisfaction with an UWETP PPP to determine the factor structure of the model. Then, confirmatory factor analysis was used to verify the goodness of fit between the model and original data. Finally, IPA was applied to assist SPV in diagnosing potential management defects and determine the priority of water environment treatment for the sample of respondents based on SEM analysis. These findings provide a reference for the evaluation of public satisfaction in eco environmental PPP projects. Moreover, the findings can inform strategic analysis to improve the allocation of limited resources more effectively.

Analysis on Financing Risk of Waste Treatment PPP Project in Tianjin: An Empirical Analysis Based on Grey Correlation Degree
PPP is a new and effective financing mode for large scale infrastructure construction, which has a broad development prospect. However, the progress of the project is not satisfactory. There are many reasons for the difficulty in landing PPP projects. However, according to the research, the key reason is the long construction cycle and low return on investment, which lead to the financing difficulty and high risk. Based on this, this paper investigated the pre construction environment of the PPP project of the newly built domestic waste comprehensive treatment plant in Dongli district of Tianjin, by using Delphi method to establish a set of scientific and reasonable risk evaluation index system, and the entropy weight method is used to determine the weights of various risk factors, on the basis of the grey correlation method was used to construct the financing risk assessment model. According to this model, the risks faced by all major participants in the project are analysed and evaluated, and the results can provide references for the investment decisions of all participants, thus promoting the rapid and smooth development of PPP projects.

Risk Evaluation of Sewage Treatment PPPABS Projects Using Combination Weight Method and D S Evidence Theory
In order to make up for the shortage of public private partnership (PPP) model, more and more sewage treatment PPP projects have adopted the asset backed securitization (ABS) model. To ensure success of sewage treatment PPPABS projects, risk evaluation, which has remained scarcity and unscientific, is becoming an urgent problem to be solved. Firstly, this paper identifies critical risk factors by literature analysis and expert interview. The final risk system is established from the perspectives of macrorisks, basic asset risks, transaction structure risks, operational risks, and other risks, which include 17 second risk factors. Then, the overall risk evaluation method is proposed based on combination weight method and Dempster Shafer (D S) evidence theory. Next, Beijing capital Co. Ltd. sewage treatment PPPABS project as a case is employed to verify the feasibility and effectiveness of the proposed method. Finally, awareness of existing risks, suggestions from law risk, quality risk, underwriting and issue risk, and credit enhancement are provided for sewage treatment PPPABS projects. All above studies are expected to provide helpful references for evaluating overall risk of sewage treatment PPPABS projects.

Stakeholder Associated Risks and Their Interactions in PPP Projects: Social Network Analysis of a Water Purification and Sewage Treatment Project in China
As a result of complex contractual relationships, multiple stakeholders with different interests are involved in public private partnership (PPP) projects. Compared to traditional models, PPP projects have more uncertainty. This study integrated stakeholders and risk factors in PPP projects from a network perspective to better determine how to control risks. Using social network analysis (SNA) a case study was conducted to identify the critical risk factors, and mitigation actions are proposed. The results indicated that, compared to other stakeholders, local governments play the most important role in PPP projects. Managers should therefore pay more attention to political and legal risk factors and develop reasonable risk sharing plans. This study expands PPP risk research from the individual level to the network level and provides a visualized, innovative research paradigm for PPP risk analysis. The results can also be used by project managers for decision making, risk management, and other processes, thus helping to achieve the sustainable management of PPP projects.

An exploration of comprehensive evaluation method of sewage treatment construction project in small and medium towns: theory and application
Based on the investigation of Chinese sewage treatment construction projects, it is of importance to develop a comprehensive evaluation method associated with socioeconomic and environmental consideration, especially in small and medium towns. A comprehensive evaluation method was established based on analytic hierarchy process method with the quantitative or semi quantitative evaluation indexes from field of technical benefit, economic benefit, environmental benefit, and social benefit. The weights of technical benefit, economic benefit, environmental benefit, and social benefit were 0.4597, 0.3437, 0.1272, and 0.0694, respectively. The technical and economic benefits were relatively more important. A practical sewage treatment plant in Economic Development Zone of Huangzhou, China, was put forward to test and verify this improved method. Results indicated that the pretax financial internal rate of return (FIRR) (7.43% and after tax FIRR (4.53% of the plant were all greater than benchmark yield of sewage treatment industry (5% pretax and 4% after tax) The pretax payback period (Pt) was 15.34 years, while that of after tax was 15.77 years. In addition, environmental benefit evaluation indicated that environmental cost benefit ratio was 1.38 in the first phase and 1.67 in the second phase, which meant positive benefit for environment. Evaluation of technical benefit and social benefit also confirmed that the project meet demands of the industrial park and society. The final comprehensive benefit evaluation result was 7.0249, which indicated that the sewage treatment plant was in average level to maintain normal operation.

Compensation mechanism for urban water environment treatment PPP project in China
Abstract The urban environment is the basis for the survival of urban residents. Thus, the government must improve its governance given the unoptimistic urban water ecological environment. The progress on the urban water environment treatment project (UWETP) is slow because of government financial pressure, efficiency of governance, and other problems. New approaches are provided for urban water environment treatment with the development and application of a public private partnership (PPP) model. However, designing a government compensation mechanism under the water environment treatment PPP projects relates to the effect of the water environment treatment. In accordance with the characteristics of the urban water environment treatment PPP projects, two standards are established in this paper. "Basic standard" indicates the minimum social and ecological benefits that the water environment treatment project should meet, and "demonstrative standard" denotes the ideal effect that the UWETP is expected to satisfy. A governmental compensation method for urban water environment treatment PPP projects is also formed from this incentive perspective. Furthermore, the economic benefits of the urban water environment treatment are considered, and game theory is adopted to solve the incentive coefficient. Therefore, a comparatively effective governmental compensation mechanism is established to provide a reference to implementing urban water environment treatment PPP projects.

Equitable Distribution of Wastewater Treatment PPP Project on Shapley Value Method with ANP Risk Correction
The wastewater PPP project possesses three characteristics: partnership, benefit sharing and risk sharing.The random cooperation game can fit the process well. The research focus of this paper is how to realize the fair allocation in the real PPP project. The paper firstly uses the cooperative game to analyze the benefit sharing, and thinks that it should be based on the contribution of the participant to the fair distribution, especially Shapley value. In addition, due to the inherent loss of Shapley value and the characteristics of the PPP project, it is necessary to consider the risk factor. The paper uses ANP super matrix to correct the distribution of risk, which can more scientifically reflect the distribution of PPP model nature.

A Comprehensive Evaluation Method for Industrial Sewage Treatment Projects Based on the Improved Entropy TOPSIS
Sewage treatment and reuse have always been hot issues in both the business and academic communities in all nations around the world. In order to solve the difficulties in accurate quantization and objective evaluation of industrial sewage treatment projects, this paper proposed a comprehensive industrial sewage treatment project evaluation method based on the improved entropy TOPSIS method. First, this paper constructed an evaluation indicator system for sewage treatment projects from the four aspects of environmental performance, economic performance, managerial performance and social performance. Second, it made a modification to the experts' experience based grading using the entropy weight method and determined the weight of the indicators in a more objective and more accurate manner. Third, this work improved the traditional TOPSIS method and simplified the calculations with regard to the traditional TOPSIS based comprehensive evaluation. Finally, by taking the example of evaluating industrial sewage treatment projects of the China Water Affairs Group in Q city (ChongQing) China, this paper verified the feasibility and practicability of the proposed comprehensive industrial sewage treatment project evaluation system and method.
