基于全球10大集装箱班轮公司777个港口的航线连接数据,统计海上丝绸之路沿线26个国家之间的海运联系情况,以国家为节点,分别构建以国家拥有航线数量和月平均贸易次数为权重的加权海上丝绸之路海运网络。结合优势流(dominant flow)和显著流(significant flow)分析方法对海上丝绸之路海运网络的层次体系进行研究。结果表明:航线数量加权网络具有明显的层次结构,贸易次数加权网络也具有一定的层次结构,但是并不明显;在两种加权网络中,阿联酋都属于第一层次,是海上丝绸之路海运网络中的核心国家;由多重流分析结果得出,中国和新加坡这两个世界航运大国在海上丝绸之路海运网络中均处于第二层次。
Based on the route connection data of 777 ports of the world’s top 10 container liner companies and statistics on the maritime links among 26 countries along the Silk Road, we use the country as the node to construct the weights for the number of national owned routes and the monthly average number of trade respectively Weighted Maritime Silk Road Maritime Network. Combining the dominant flow and the significant flow analysis method, the paper studies the hierarchy of maritime Silk Road maritime networks. The results show that there is a clear hierarchy in the number-weighted network of routes, and the weighted number of trade networks also has a certain hierarchy, but it is not obvious. Among the two kinds of weighted networks, the UAE belongs to the first level and is the maritime Silk Road maritime network China and Singapore, the two big shipping nations in the world, are all on the second level in the maritime Silk Road maritime network.
