将世界集装箱班轮运输划分为18个海运区域,根据17家主要班轮公司593个港口的航线连接数据统计18个海运区域间的航线连接情况,构建以连接频率为权重的加权世界集装箱海运网络.结合优势流分析和显著流分析对海运网络的层次结构进行研究,结果表明世界集装箱海运网络具有明显的层次性,可分为四层.各层次区域之间存在海运联系且不同层次的区域在网络中具有不同的作用,第一层次海运区域处于核心地位,第二层次及第三层次的部分海运区域的中介性较强.在此基础上,进一步探讨东亚和西北欧两个核心区域与其他区域的相对海运距离,分析海运区域间的内在联系.
According to the route connection data of 593 ports of 17 major liner companies, the world containerized liner shipping is divided into 18 maritime areas, and the route connections among 18 maritime areas are collected to construct a weighted world container shipping network weighted by the connection frequency. Dominance flow analysis and significant flow analysis of the hierarchy of the maritime transport network, the results show that the world container shipping network has a clear hierarchy, can be divided into four layers.All levels of regional maritime transport linkages and different levels of the region in the network Has a different role, the first level of the maritime transport area is at the core, the second and third levels of some maritime transport areas are more intermediary, and on this basis, to further explore the two core regions of East Asia and Northwest Europe and other regions Relative maritime distance, analysis of the maritime inter-regional relations.
