世界集装箱海运网络社团结构研究

从复杂网络的角度，探讨世界集装箱海运网络的结构特性，并提出了海运区块划分的新视角. 根据最新数据，验证海运网络的小世界和无标度特征. 基于模块度理论及分辨率理念，将网络进一步细分形成特征各异的三大海运区域和八大区块. 研究结论为：世界集装箱海运网络度分布符合幂为-8.96 的幂律分布；海运网络分布受海峡、运河等自然地理空间限制，具有显著的地理特征；各海运区块活跃程度不一，可以用航线密度为基础的加权平均度变化衡量；海运区块同样具有小世界和无标度特性，且不受网络规模影响；区域枢纽港的聚类系数普遍趋近0.2，为识别大型中转枢纽港提供依据.

Community Structure of World Container Shipping Network

Based on the complex network theory, this paper discusses the structural characteristics of the world container shipping network and provides a new perspective on the division of maritime regions. The up- to- date data verified the small world and scale- free characteristics of the shipping network. According to the concept of modularity and its resolution, the network is further subdivided into three major maritime regions and eight blocks. The main research findings are: Network distribution is in accordance with the power law distribution (power: - 8.96); Layout of maritime blocks have obvious spatial characteristics restricted by natural geography like straits and canals; Maritime blocks are different in vitality which can be measured by the change of average weighted route density; Maritime blocks also have small worlds and scale-free characteristics in spite of the block scale; The clustering coefficient of regional hub ports generally approaches 0.2, providing a basis for identifying large transit hub ports.
