Research On Regional Port Investment Decision In The Background Of Maritime Silk Road

The 21st Century Maritime Silk Road Initiative is a new type of regional cooperation mechanism that is adapted to the development of the times.It is of great significance in promoting the economic integration of Asia and Europe,promoting regional interconnection and security,and ensuring maritime traffic safety.China has led the esTab.Iishment of multilateral financial institutions such as the Asian Infrastructure Investment Bank,the New Development Bank,and the Silk Road Fund,with the aim of providing financial support to developing countries with weak infrastructure along the route and promoting the interconnection and construction process.However,historical experience shows that unreasonable port investment will lead to problems such as unclear port division,low-level redundant construction,unreasonable port structure,and inefficient logistics network.Therefore,how to make reasonable regional port investment decisions within the limited financial constraints,aiming at improving the overall performance of the regional port system,and ensuring the leadership of the Maritime Silk Road initiative has important research value.This paper takes the regional port investment decision under the background of Maritime Silk Road as the research object,and esTab.lishes a comprehensive optimization model considering the optimal performance of the regional port transportation network system and the dynamic feedback of the cargo owner.The main research contents include:(1)Firstly,it summarizes and sorts out the background of the Maritime Silk Road,the concept of regional ports,application methods and theories,and then summarizes the research status from three aspects:port hinterland economy,investment situation,marine traffic environment and infrastructure.Among them,the complex network theory and the node contraction method are applied to calculate the port accessibility index.The results show that the Southeast Asia region is the hub area of the port network along the Road.(2)Bilevel Programming model for regional port investment decisions in the context of the Maritime Silk Road was constructed.The model esTab.lishes a port investment management organization,and the upper model makes investment decisions with the goal of optimizing the performance of the regional port transportation network system,so that the total travel impedance of the post-investment system is minimized within a limited investment amount constraint.The lower model is the distribution model under the user equilibrium assignment,so that the owner can select the least cost cargo transportation path under the influence of the upper decision information.Finally,the genetic-Frank Wolfe algorithm was designed and solved using Matlab software.(3)Based on the particularity of the Southeast Asia region along the Maritime Silk Road,the Southeast Asia-China regional port network is used as an empirical analysis to obtain the conclusion of this paper.The results are conducive to revealing the mutual feedback law of freight demand and port construction,which is conducive to guaranteeing the leadership of the Maritime Silk Road initiative and providing theoretical support for regional port investment decision-making.The innovation of this paper is as follows;Based on the Maritime Silk Road Initiative,a port coordination model across national and inter-administrative areas has been esTab.lished,which has jumped out of the limitations of port coordination in the same administrative areas and the bay.The innovative application of the improved BPR function is applied to the relationship between port investment and cost,and the relationship function between port investment and port impedance is reasonably constructed.
