【摘要】：在"一带一路"战略实施的背景下,为了解全球集装箱运输网络中区域之间的关系及各区域在海运网络中的枢纽作用对全球物流行业发展的影响,以复杂网络为理论基础,以国家为单位将全球海运网络划分为155个区域,使用网络平均度、网络密度和中介中心性分析评价全球海运网络中各区域内部及各区域之间的海运网络结构,提出紧密指数作为评价区域之间联系紧密程度的指标之一。计算显示,全球海运网络具有无标度特性,可以将其抽象为复杂网络来分析;区域的中介中心性和紧密指数存在正相关关系;仅有8%的区域对整个海运网络的连通性带来显著影响。研究结果表明,国家港口数量在1~5之间的占国家总数量的85.34%;区域内部港口数量会直接影响该区域在海运网络中的参与度;在全球海运网络中发挥枢纽作用的区域有83.3%分布于欧洲和亚洲。
[Abstract]:In the context of the implementation of "Belt and Road" strategy, in order to understand the relationship between regions in the global container transport network and the impact of the regional pivotal role in the maritime transport network on the development of global logistics industry, the complex network is the theoretical basis. The global maritime transport network is divided into 155 regions in terms of countries. The network structure within and between regions in the global maritime transport network is evaluated using network average, network density and intermediary centrality. The closeness index is proposed as one of the indexes to evaluate the degree of close connection between regions. The calculation shows that the global maritime transport network has scale-free characteristics and can be abstracted as a complex network to be analyzed, and there is a positive correlation between the regional intermediary centrality and the closeness index. Only 8% of the regions have a significant impact on the connectivity of the entire maritime network. The results show that the number of national ports in the range of 1 / 5 accounts for 85.34 of the total number of countries, and the number of ports within the region will directly affect the participation of the region in the maritime transport network. 83.3% of the regions that play a pivotal role in the global maritime network are in Europe and Asia.
