泛北部湾经济区海上运输网络结构模式及发展对策研究

Research on the Structure Model of Pan-Beibu Gulf Economic Zone Maritime Transportation Network

泛北部湾经济区是中国与东盟国家深入合作的重要窗口,开展这一地区海上运输网络结构研究,对揭示中国与东盟航运发展的基本规律、提升中国华南地区港口群竞争力具有重要意义.本文基于集装箱船AIS数据,通过构建开放流网络模型研究了泛北部湾经济区集装箱航运网络结构,并运用节点流量控制影响力评价方法识别出网络的关键港口.研究发现:泛北部湾经济区海上运输网络具有明显的马太效应,呈现松散结构;枢纽港对网络的影响力与其吞吐量存在显著差异.华南地区港口群应在高质量发展的新常态下,建立跨区域协调机制,推动港口业务“多元化”向区域“基地化”发展,逐步形成优势互补、分工合理、相互协作、竞争有序的华南地区港口群.

The Pan-Beibu Gulf Economic Zone is an essential window for in-depth cooperation between China and ASEAN countries.Researching the maritime transportation network structure in this region is of great significance for revealing the fundamental laws of shipping development between China and ASEAN and improve the competitiveness of the port group in South China.Based on the AIS data of container ships,this paper studies the container shipping network structure of the Pan-Beibu Gulf Economic Zone by constructing an open-flow network model.Moreover,the node flow control influence evaluation method is used to identify the critical ports of the network.The study found that the maritime transportation network of the Pan-Beibu Gulf Economic Zone has an obvious Matthew effect and presents a loose structure.There is a significant difference between a hub port's influence on the network and its throughput.The port group in South China should establish a cross-regional coordination mechanism under the new normal of high-quality development to promote the"diversification"of port business toward regional"base-based"development.Gradually form a South China port group with complementary advantages,reasonable division of labor,cooperation,and orderly competition.
