【摘要】：世界海运网络具有明显的复杂性,是典型的复杂网络。其中的大量港口、船舶、航线等,都处于动态演化的过程当中。研究世界海运网络的演化及其演化动力,可以从整体宏观的角度考察世界海运网络的本质和运动规律,有助于深入了解并合理适应世界海运网络,从而科学制定相关建设规划。目前对于世界海运网络的研究方法仍然较多的关注于个体和局部层面,虽然也取得了一些有益的成果,但是不可避免地缺失了许多整体层面的信息。而复杂网络理论可以利用对现实世界的数学抽象,从整体的视角来描述元素以及元素之间的相互作用和关系。因此,本文利用复杂网络的基本理论与研究方法,将世界海运网络中的港口视为网络中的节点,将港口与港口之间的航线视为网络中的边,从而将世界海运网络中的港口、航线及其复杂关系直观地抽象为复杂网络拓扑图。本文主要着眼于世界海运网络的结构演化及其演化动力研究。第一,在对中外学者研究现状进行系统梳理和总结的基础上,认为应当以复杂网络的基本理论和基本研究方法为基础,并运用改进的演化假设和演化模型对世界海运网络进行分析；第二,明确了世界海运复杂网络的概念、主要特点,以及世界海运复杂网络演化的主要影响因素;第三,利用优先连接原则,构造出解决世界海运复杂网络演化动力研究问题的世界海运复杂网络演化基本模型；第四,根据已构建的世界海运复杂网络演化基本模型,利用计算机进行模拟实验,对模拟结果进行比对和分析,并进一步结合几个相关网络模型进行对比分析；第五,根据世界海运复杂网络演化基本模型的计算机模拟实验结果,归纳总结了驱动世界海运复杂网络演化的动力机制。通过对世界航运复杂网络演化动力的研究,宏观地了解各个地区之间的海运联系,可以为分析各个地区之间的运输、贸易、经济联系等提供理论依据,为合理分布航线以及提高网络效率等提供理论参考,并为国家港口规划和建设提供理论支持。
[Abstract]:The world shipping network has obvious complexity and is a typical complex network.A large number of ports, ships, routes and so on, are in the process of dynamic evolution.The study of the evolution of the world maritime transport network and its evolutionary power can investigate the nature and movement of the world maritime transport network from the overall macro point of view, which is helpful to understand and reasonably adapt to the world maritime transport network, so as to scientifically formulate the related construction plan.At present, the research methods of the world maritime transport network still pay more attention to the individual level and the local level. Although some beneficial achievements have been made, many information on the whole level are inevitably missing.The complex network theory can use the mathematical abstraction of the real world to describe the elements and their interactions and relationships from the perspective of the whole.Therefore, using the basic theory and research method of complex network, this paper regards the ports in the world shipping network as the nodes in the network, and the routes between ports and ports as the sides of the network, thus the ports in the world shipping network are regarded as the ports.Routes and their complex relationships are intuitively abstracted into complex network topology graphs.This paper focuses on the structural evolution of the world shipping network and its evolutionary dynamics.First, on the basis of systematically combing and summing up the current research situation of Chinese and foreign scholars, it is believed that the basic theories and research methods of complex networks should be taken as the basis.And use the improved evolution hypothesis and evolution model to analyze the world maritime transport network; second, define the concept and main characteristics of the world maritime complex network, as well as the main factors affecting the evolution of the world maritime complex network; third,Based on the principle of priority connection, the basic model of the evolution of the world maritime complex network is constructed to solve the dynamic problem of the evolution of the world maritime transport complex network. Fourth, according to the basic model of the world maritime transportation complex network evolution,Computer simulation experiments are used to compare and analyze the simulation results, and several related network models are compared and analyzed. Fifth, according to the computer simulation results of the basic evolution model of the world maritime complex network,The dynamic mechanism driving the evolution of the complex maritime network in the world is summarized.Through the study of the evolutionary power of the complex network of world shipping, the macroscopic understanding of the shipping links between different regions can provide a theoretical basis for the analysis of the transportation, trade and economic links among the regions.It provides a theoretical reference for the rational distribution of routes and the improvement of network efficiency, and provides theoretical support for the planning and construction of national ports.
