Research On Social Capital Selection Of PPP Projects Based On ISM-ANP And Grey Correlation Analysis

The PPP model refers to the cooperation between the government and social capital to jointly carry out the project operation mode of infrastructure and public utility projects.Under this model,the government encourages social capital such as companies,funds and individual investors to actively participate in the construction of infrastructure and public utilities projects.Therefore,the question of how to correctly choose social capital has always been a hot topic in academic research.At present,domestic research on PPP projects does not consider the relationship between indicators,nor does it combine the latest national regulations and policy dynamics.The selection of indicators for PPP projects remains at the previous level.This study aims to build an analysis model based on ISM-ANP,in order to selecting the best social capital partners through grey theory and providing an operational method for selecting social capital for PPP projects.First of all,through the analysis of the successful selection of social capital cases in the past PPP projects,this paper systematically studies the relevant documents of PPP projects in the design of evaluation index system,and combines the relevant opinions of experts to select relevant factors that have great influence on social capital selection.The index based on management ability,experience performance,financial ability,technological ability,service level and enterprise reputation,contains six dimensions of 21 indicators of evaluation index system.Secondly,on the basis of establishing the evaluation index system,the ISM model and the analytic network process method are combined,based on the recent development trend of the PPP model,combined with the latest PPP project construction,the dependence between the evaluation indicators is established,and the scientific rigor is formed.Evaluation System.Using the grey relational degree theory,the pre-selection schemes are ordered to guide the selection of the optimal social capital.Finally,a PPP project in Jining City was selected as a research case,and the social capital selection model of the established PPP project was selected to select the social capital that accords with the maximization of project benefits.At the same time,it also verifies the validity and scientificity of the construction of social capitalselection model,and provides a theoretical reference for PPP project selection of social capital.
