【摘要】：运用位序—规模法则与核密度方法,以近30年来各港口货物吞吐量及集装箱吞吐量为主要指标,刻画环渤海地区港口体系的规模分布特征,分析其作用机制。结果表明:(1)总体看,环渤海地区港口体系具有一定位序—规模分布特征,但不同阶段、不同规模的港口在位序分布上出现明显分化,港口区域化特征愈发明显。(2)港口货物吞吐量位序—规模分布的无标度区数量先增后减,最终由单分形变为双分形结构。区域港口体系经历了高位序平衡发展、中小港口突破、大中小港口差异化发展、枢纽港竞合下的港口融合四个阶段。港口集装箱吞吐量位序—规模分布的变化轨迹呈现外接式分割发展、枢纽港形成及新兴港口融入、支线港大型化和集装箱网络整合四个阶段。两者在发展节点上基本吻合;港口集中化与分散化交织进行,货物总吞吐量的分散化早于集装箱运输,分散趋势较为明显。(3)环渤海地区港口体系位序—规模演化的作用机制突出表现为自然经济地理约束下的大港口主导作用明显、区域化和竞争压力倒逼港口合作并推动港口实现自组织协调、能源输出特征及转型推动新兴港口快速成长三方面。
[Abstract]:By using the law of position-scale and the kernel density method, the port throughput and container throughput of each port in the past 30 years are taken as the main indexes to characterize the size distribution characteristics of the port system around the Bohai Sea and to analyze its working mechanism. The results show that, in general, the port system around the Bohai Sea has a characteristic of location-scale distribution, but at different stages, the port with different size has obvious differentiation in the sequence distribution. The characteristics of port regionalization become more obvious. (2) the number of scale-free region of port cargo throughput order-scale distribution first increases and then decreases, and finally changes from single fractal to double fractal structure. The regional port system has experienced four stages: balanced development of high order, breakthrough of small and medium ports, differential development of large, medium and small ports, and integration of ports under the competing and closing of hub ports. The change track of port container throughput sequence-scale distribution presents four stages: the development of external segmentation, the formation of hub port and the integration of new port, the large-scale of branch port and the integration of container network. The two are basically identical on the development node; the port centralization and decentralization are intertwined, and the total cargo throughput is decentralized earlier than container transportation. The mechanism of sequence-scale evolution of port system around Bohai Sea is obvious. The dominant role of large ports under the restriction of natural economy and geography is obvious. Regionalization and competitive pressure force port cooperation and promote port self-organization coordination, energy export characteristics and transformation to promote the rapid growth of emerging ports.
