| At present,the development situation of the PPP project is not optimistic,the government financial pressure is huge,and the participation of social capital is not high.Therefore,the relevant state departments have been calling for mining their own commercial value while ensuring the publicity of the PPP project,meanwhile,the additional income generated in the follow-up development of commercial value is also the focus of public and private attention.In view of this,this paper studies the development of additional commercial value,and adjusts the benefits through an objective and reasonable distribution scheme,in order to promote the benign development of PPP projects.(1)The development of additional commercial value of PPP project is defined and analyzed.Firstly,through sorting out the operating terms of the PPP project contracts which are newly stored and open at the present stage,the different types of operating income are classified.Secondly,with "added value" and "commercial value" as the theoretical support,combined with related literature similar to added business value,to define the added business value,PPP project return mechanism as the entry point,combined with the two characteristics of the goods,a systematic and comprehensive analysis and summary of the development of added business value of PPP projects.Finally,it discusses the positive role that the government should play in the development of added commercial value in PPP projects,so as to promote the smooth implementation of added commercial value development in PPP projects more effectively.(2)It provides a new way to evaluate the actual contribution in the development of added commercial value of PPP projects.Firstly,based on the problem that it is difficult to realize the identification and evaluation method of the performance behavior of the best performance at the present stage in the actual project,the innovative idea of replacing the performance behavior of the best performance with risk is put forward and analyzed.Secondly,the development of added business value of PPP projects is divided into three stages: conception and research,exploration and design,and trial implementation.According to the characteristics of each stage,the risks that may be faced in the development of added business value are preliminarily identified by brainstorming method,and then the final screening and confirmation of initial risks are made by Delphi method.Finally,according to the identified risks at each stage,the hierarchical analysis model is established,and the AHP-CRITIC method is applied to evaluate the risks the public and private parties are dealing with in the development of additional business value,and the risk impact weight is obtained,so as to characterize the actual contributions of both parties in the development of additional business value.(3)In view of the deficiencies in the allocation of super profits of PPP projects according to the proportion agreed in the contract,the actual contribution of the public and private parties in the development of additional commercial value is comprehensively considered,and the adjustment is made on the basis of the sharing.Therefore,it is necessary to revise the asymmetric Nash negotiation model simply,simulate the risks that the public and private parties may encounter in the development of additional business value in reality through the case,identify and evaluate them,and represent their actual contributions by the impact degree of the risks they deal with,so as to fully link the actual efforts of both parties with the final income,so as to make the distribution results fairer and more scientific.In order to better encourage social capital to actively participate in the development of additional commercial value,to promote the long-term development of PPP projects. |
