Research On The Key Risks Of Public And Private Parties In Underground Pipe Corridor Under PPP Model

As a kind of intensive,scientific and sustainable new urban infrastructure,the underground integrated corridor has been widely promoted in the field of public affairs in our country.The policy has been growing rapidly and the number of projects has increased rapidly.However,compared with the developed countries,China's underground corridor construction level is still very backward,is still in the initial stage,the theoretical research system is not perfect,can not meet the needs of urbanization.For the Western advanced research experience,can only learn can not be copied,based on China's national conditions reasonable development underground corridor.Therefore,in the case of insufficient government resources,the introduction of social capital,the use of PPP mode development of underground corridor construction,to achieve a win-win situation,but also can significantly improve the quality of public facilities services.China's PPP mode under the underground corridor project to promote the application is also facing a series of problems,including the understanding of PPP is not uniform,heavy financing light operation,social capital participation is not active,government capacity defects,etc.,at the same time,PPP mode underground pipe The project has a large number of partners,the uncertainty is large,and the investment of the corridor project is huge,the investment payback period is long,the construction operation period is long,the contract content is complicated,the project negotiation is time-consuming and often can not be fulfilled in the project implementation process dispute.Among them,a large reason is that the public sector and social capital between the lack of critical risk of comparative analysis.At present,there are few studies on the risk of underground corridor in PPP mode,and there is no comparative study on the sensitivity of public and private to the sensitivity of public and private.The results of this paper have expanded the risk of underground corridor Research the scope of the field,has a certain theoretical significance.Based on the theory of gray relational degree,this paper starts from the perspective of public sector and social capital,and validates the list of comprehensive corridor risk in PPP mode through literature analysis,and uses the gray relational model to analyze the key risks of public sector and social capital This paper tries to draw out the main contradictions in the risk management between the public and private parties,and then formulate a reasonable risk-sharing coping strategy to provide reference for the public-private investment decision of underground corridors in PPP mode.In this paper,according to the PPP model of integrated corridor public and private risk management issues,are divided into six chapters.The first chapter is the introduction,summarizes the research status quo at home and abroad,puts forward the basic situation of the paper from the public and private research methods to identify the risk,the gray correlation model to analyze the risk factors,The second chapter is the related concept and theoretical basis.It introduces the concept and characteristics of the underground corridor under the PPP model,the project risk management theory and the gray relational degree theory.In the third chapter,the construction of the risk index system of the underground corridor project under the PPP mode is constructed through the literature research method,and the risk index is analyzed and analyzed.The fourth chapter introduces the gray relational model and its applicability to the PPP project,and arranges the questionnaires of the public and private questionnaires.The questionnaire is mainly sent by the WeChat and the paper questionnaires.A total of 100 copies are issued,45 valid questionnaires are collected,The risk of the risk of the risk of the public sector,the impact of the risk on the social capital of five dimensions,the use of gray correlation model,statistics out of the pipe project before the project 5 key risks,on this basis,respectively,the public sector and social capital of the first five key risks.In the fifth chapter,based on the five key risks of the corridor project,social capital and public sector,we focus on the comparative analysis of the top five key risks of social capital and public sector,and make a reasonable explanation of the difference between the two,And make the appropriate recommendations.In the sixth chapter,summarized the results of this paper and prospects the future research.
