基于灰色关联度的PPP项目私营部门的选择模型

Study on the Selection Model of Private-sector in PPP Project Based on Gray Relevancy

公私合作(PPP)项目中,公共部门选择合适的私营部门"联姻"是项目成功的关键因素之一.运用文献频数分析法甄选出评价私营部门的有效指标,并从财务能力、技术能力、管理能力、过往经验以及声誉水平五方面建立相应的指标体系;运用熵值法来确定各项指标的权重.以灰色加权关联度高低为遴选评价方案的依据,基于灰色关联理论构建PPP项目公共部门选择私营部门的决策模型,并通过实例论证该模型的实用性及有效性,为PPP项目私营部门选择提供一种路径.

In the PPP project, the public-sector choosing an appropriate private-sector establishing “Marriage” relationship is one of the key factors for success. First, constructing the index system of private-sector based on the document frequency method, which considered financial ability, technical skills, management ability, past experience and reputation level. The entropy value method is used to determine the weight of indexes, and the grey relation theory is used to measure grey correlation degree of evaluation schemes so as to construct government decision-making model of the selection of private-sector in PPP project. Finally, a case is given to prove that the model is practical and effective, which provides a path for private-sector choosing of PPP project.
