珠三角港群集装箱货流空间分布的脆弱性

Spatial Distribution in Container Cargo Flow of Pearl River Delta Port Cluster

本文在构建全球集装箱港口网络的基础上,抽取以珠三角主要的集装箱港口为核心的子网络,并对港口之间的运力配置进行统计,最终得到一个以港口为节点,以港口之间的运力为边权重的有向加权网络。在此基础上结合复杂网络理论,以海向腹地为研究视角,从进口货流和出口货流两个方面分别对珠三角港口群集装箱货流在全球的空间分布格局进行分析,探究其货流在全球主要海运区域分布的脆弱性。结果表明珠三角港口群与南美北岸、南亚、东非以及北非等海运区域之间的货流分布最脆弱。

This paper extracts a sub-network which on the core of Pearl River Delta container port from global container port network, then counts the shipping capacity between ports, and finally we get a directed and weighted port network. Basing on complex network theory, this paper focuses on the foreland of ports, researches the global spatial distribution in container cargo flow of Pearl River Delta port cluster from inward and outward respectively, studies the vulnerability between Pearl River Delta port cluster and other shipping area, the results show that the most vulnerable connection exists in South America North Coast, South Asia, East Africa and North Africa.
