摘  要:为了科学地选择出与污水处理PPP项目相匹配的运作方式,在分析探讨污水处理PPP项目运作特征与运作方式分类的基础上,建立了包含项目自身特征、政府能力、项目实施、项目收益、融资风险五个方面的污水处理PPP项目运作方式选择指标体系。运用DEMATEL主观赋权法与信息熵客观赋权法相结合的方式对指标体系进行组合赋权,使用灰色关联理论改进TOPSIS法,优化相对贴近度的计算形式,构建了基于组合赋权与GRA-TOPSIS的污水处理PPP项目运作方式选择模型。而且,运用该模型对青岛市某污水处理PPP项目运作方式选择进行实例验证。通过计算得到六种运作方式的综合排名:DBFO>BOOT>股权转让>DBTO>DBO>BOO,由此确定DBFO是该项目的最佳运作方式,证明了该方法能够对污水处理PPP项目运作方式作出科学、准确的判断,能为污水处理PPP项目的未来发展提供一定的帮助。In order to scientifically select the operation mode that is matched with the wastewater treatment PPP project,an index system for selecting the operation mode of wastewater treatment PPP project,which includes five aspects,i.e.self-characteristics of project,government capabilities,project implementation,project benefit and financial risk,is established on the basis of analyzing and discussing both the characteristics and mode classification of the wastewater treatment PPP project,and then the combination weighting is made on the index system through the mode of combining the subjective weighting method of DEMATEL with the objective weighting method of information entropy,while a combination weighting and GRA-TOPSIS-based model for selecting the operation mode of the wastewater treatment PPP project is established by means of the calculation mode of improving TOPSIS method with the grey correlation theory and optimizing the relative closeness.Moreover,the model is applied to the case verification for selecting the operation mode of a wastewater treatment PPP project in Qingdao.Through the relevant calculation,the overall ranking of six operation modes is obtained,i.e.DBFO>BOOT>Equity Transfer>DBTO>DBO>BOO;from which DBFO is determined to be the best operation mode for that project,thus it is proved that this method cannot only make a scientific and accurate judgment on the operation mode of wastewater treatment PPP project,but can also provide a certain assistance for the future development of wastewater treatment PPP project.
