Research On Selection Of Partner In The Pension PPP Projects Based On Hybrid Mulitiple Attribute Group Decision Making

PPP model is favored by the global governments for the advantages of easing financial pressure and increasing public goods supply efficiency.In September 2014,China's Finance Ministry published the notification about promoting relevant issues about the use of government and social capital on the cooperation mode,which declared the promotion of PPP model demonstration projects across the country.After that the whole society set off the enthusiasm for developing PPP mode.However during the PPP's long franchise period,the partner is responsible for important role of financing constructing and operating,who has critical influence on the success of PPP projects.Moreover the PPP model in China has been introduced to the old-age field in a short time,there is still no successful case that could be learnt from.In such a situation choosing the right partner is more important.Effectively selecting partner not only needs a scientific evaluation index system but also requires a valid evaluation method.In view of this,this paper centers on the partner selection index system and the methods of evaluation to launch the research.The main results of this paper are as follows:Firstly this paper established the index system of partner selection from the perspective of general construction of PPP projects through the document analysis.And the ability to cooperation,risk sharing,interests and other content were also considered into the index system.Then concluding the personality indicators based on characteristics of pension PPP projects.After that optimized the index system with the help of questionnaire,then obtained the optimal index system that made up by 6 dimensions and 26 indicators.Secondly this paper used the multiple attribute group decision making method(HMAGDM)to build the selection model based on the reality of mixed data exiting on the evaluation applications.The model should get the evaluation values to form the mixed evaluation matrix as the first step.Then using the concept of similarity to measure the experts' weight and gather the individual preference to for group preferences.After that Entropy method was used to calculate the index weights.Compared to the existing research,this model taked mixed information of expert evaluation into account adequately.This will ensure the practical and scientific of the model.Thirdly the TOPSIS method was introduced to solve the model which used the"Vertical"distance instead of the traditional "European" distance.The validation and feasibility of the model was validated by the examples.Through the above study,this paper has greatly enriched the theory of PPP project and expanded the field of application of HMAGDM method.The result of the study may help the government select the optimal partner to guarantee the smooth implementation of PPP projects.At the same time the model can help the government improve project efficiency and reduce administrative arbitrariness during the process.
