【摘要】:世界海運網絡具有明顯的復雜性,是典型的復雜網絡。其中的大量港口、船舶、航線等,都處于動態(tài)演化的過程當中。研究世界海運網絡的演化及其演化動力,可以從整體宏觀的角度考察世界海運網絡的本質和運動規(guī)律,有助于深入了解并合理適應世界海運網絡,從而科學制定相關建設規(guī)劃。目前對于世界海運網絡的研究方法仍然較多的關注于個體和局部層面,雖然也取得了一些有益的成果,但是不可避免地缺失了許多整體層面的信息。而復雜網絡理論可以利用對現實世界的數學抽象,從整體的視角來描述元素以及元素之間的相互作用和關系。 因此,本文利用復雜網絡的基本理論與研究方法,將世界海運網絡中的港口視為網絡中的節(jié)點,將港口與港口之間的航線視為網絡中的邊,從而將世界海運網絡中的港口、航線及其復雜關系直觀地抽象為復雜網絡拓撲圖。本文主要著眼于世界海運網絡的結構演化及其演化動力研究。第一,在對中外學者研究現狀進行系統(tǒng)梳理和總結的基礎上,認為應當以復雜網絡的基本理論和基本研究方法為基礎,并運用改進的演化假設和演化模型對世界海運網絡進行分析;第二,明確了世界海運復雜網絡的概念、主要特點,以及世界海運復雜網絡演化的主要影響因素;第三,利用優(yōu)先連接原則,構造出解決世界海運復雜網絡演化動力研究問題的世界海運復雜網絡演化基本模型;第四,根據已構建的世界海運復雜網絡演化基本模型,利用計算機進行模擬實驗,對模擬結果進行比對和分析,并進一步結合幾個相關網絡模型進行對比分析;第五,根據世界海運復雜網絡演化基本模型的計算機模擬實驗結果,歸納總結了驅動世界海運復雜網絡演化的動力機制。通過對世界航運復雜網絡演化動力的研究,宏觀地了解各個地區(qū)之間的海運聯系,可以為分析各個地區(qū)之間的運輸、貿易、經濟聯系等提供理論依據,為合理分布航線以及提高網絡效率等提供理論參考,并為國家港口規(guī)劃和建設提供理論支持。
[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.
