全球贸易量的80%左右是通过海运，因此海运系统是世界经济的基础。为了更好地开发新的国际航线，我们需要了解现有的航线及其与国际贸易相关的复杂系统。本文研究了全球班轮运输网络的结构，发现它是一个经济的小世界网络，在高运输效率和低布线成本之间进行权衡。为了加强对这种权衡的理解，我们研究了模块化隔离的GLSN，我们研究省，连接器枢纽港口，并提出网关枢纽港口的定义，使用三个各自的结构措施。门户-枢纽结构-核心组织是大物流网络的一个显著特征，它与网络整合和实现国际贸易货物运输的功能密切相关。这一发现提供了新的见解GLSN的结构组织的复杂性和它的相关性，国际贸易。
Around 80% of global trade by volume is transported by sea, and thus the maritime transportation system is fundamental to the world economy. To better exploit new international shipping routes, we need to understand the current ones and their complex systems association with international trade. We investigate the structure of the global liner shipping network (GLSN), finding it is an economic small-world network with a trade-off between high transportation efficiency and low wiring cost. To enhance understanding of this trade-off, we examine the modular segregation of the GLSN; we study provincial-, connector-hub ports and propose the definition of gateway-hub ports, using three respective structural measures. The gateway-hub structural-core organization seems a salient property of the GLSN, which proves importantly associated to network integration and function in realizing the cargo transportation of international trade. This finding offers new insights into the GLSN’s structural organization complexity and its relevance to international trade.
