【摘要】：近年来,随着中国经济结构的调整,中国港口也进入了转型调整阶段,正从以往的外延式扩张向内涵式发展转变,由原来的混沌式竞争向层次化布局过渡,港口的层次化发展是港口经济发展的必然要求和发展趋势,目前,国内外学者对于港口层次划分的研究相当匮乏,尤其是缺少宏观的港口航运网分析。为此,在传统复杂网络基础上,构造了加权复杂网络揭示港口航运网的拓扑结构特点,选取复杂网络指标,通过聚类分析对网络中的港口节点进行层次划分,并以中国港口航运网为例进行实证分析,首先得出中国港口航运网具有“小世界”、无序性等特点,然后依据拓扑结构特点及各指标之间的相关性,选取指标将中国的港口划分为四个层次,最后通过对结果进行分析,得出中国港口目前的发展状况及未来的布局规划。
[Abstract]:In recent years, with the adjustment of China's economic structure, Chinese ports have also entered the stage of transformation and adjustment, from the former extension of expansion to the connotation of development, from the original chaotic competition to the hierarchical layout transition. The hierarchical development of the port is the inevitable requirement and development trend of the port economic development. At present, the domestic and foreign scholars' research on the port hierarchy is rather scarce, especially the lack of macroscopic port shipping network analysis. Based on the traditional complex network, the weighted complex network is constructed to reveal the topological characteristics of the port and shipping network, and the complex network index is selected, and the port nodes in the network are divided by clustering analysis. Taking China's port and shipping network as an example, the author first draws the conclusion that China's port and shipping network has the characteristics of "small world" and disorder, and then according to the characteristics of topological structure and the correlation between each index. The indexes are selected to divide the ports of China into four levels. Finally, through the analysis of the results, the present development situation and future layout planning of the ports in China are obtained.
