| As the fulcrum of China’s "One Belt,One Road" construction,port projects can add impetus to national and even global economic growth,while the limitations of China’s traditional investment,financing and construction model constrain the development of port projects.Therefore,the introduction and rational application of PPP model can speed up port construction and promote port management to a new level.The core of PPP project fees is pay-for-performance,whether for availability,operation and maintenance,or user fees are linked to the level of management of the project company.Therefore,there is a need to systematically study and design payment mechanisms for the construction and operation management of port projects,so that the public sector can be informed and the private sector can improve its own management level to provide better port services.Firstly,based on the differences and similarities in the development of payment mechanisms for PPP projects at home and abroad,a general framework for the payment mechanism of port PPP projects suitable for China’s national conditions is proposed.Secondly,according to the process of port project availability realization and combined with norms and standards,20 main indicators affecting the availability of port PPP projects are proposed.Meanwhile,based on the risk of changes in the total investment amount of PPP projects,the risk-sharing payment adjustment model based on investment changes is constructed.In addition,the thesis designs the relevant guidelines for rewarding and deducting the availability payment of port PPP projects by combining the quality,safety,investment and schedule of port projects.Thirdly,Based on the characteristics of port project operation and maintenance,the thesis proposes 31 main indicators affecting port PPP projects by combining domestic and international research.By analyzing and quantifying the index weights,the thesis thus constructs a payment system for port project O&M period and incorporates the system into the reward and deduction of O&M performance fees.Furthermore,A performance-based user fee model was designed,and a performance-and concession period-based user fee adjustment method was designed with the project’s frequent revenue shortfalls and excesses as the entry point.Finally,using the Nantong Yangkou Port Bridge and Liquefaction Terminal PPP project as a background,based on its feasibility study and other data,the PPP framework agreement was improved by applying the payment mechanism concept proposed in the article,and the feasibility of the payment system was verified during the implementation of the project to achieve value for money. |
