运用复杂网络理论与聚类分析相结合的方法,以港口城市为节点构建网络,借助网络整体结构及节点中心性评价指标揭示海上丝绸之路东南亚航运网络空间格局及其沿线港口分布特征.结果表明:其网络整体呈现“T”字形结构,度分布近似符合幂指数分布规律,具有无标度特性和“小世界网络”特征;同时,从节点中心性角度分析,东南亚沿线港口局部呈现集聚特征,区域化明显,其中新加坡港、巴生港、丹戎帕拉帕斯港和雅加达港中心性值最高,建议以新加坡、马来西亚及印度尼西亚地区为主构建海上丝绸之路港口发展核心区域,同时促进区域内中小型港口建设,加强与东南亚港口的物流合作.
Using the combination of complex network theory and cluster analysis, this paper constructs a network with port cities as nodes, and reveals the spatial distribution of maritime Silk Road Southeast Asian shipping network and its distribution along the ports by means of overall network structure and central evaluation indexes of nodes. : The network as a whole presents a “T” glyph structure, the degree distribution is approximately in accordance with the law of power exponent distribution, and has the features of scale-free characteristics and “small world network ”; meanwhile, from the node center perspective, Showing the characteristics of agglomeration with obvious regionalization. Among them, Singapore, Port Klang, Tanjung Pelepas and Jakarta have the highest central value. It is suggested that the core area of the maritime Silk Road port development should be built mainly in Singapore, Malaysia and Indonesia , While promoting the construction of small and medium-sized ports in the region and strengthening the logistics cooperation with ports in Southeast Asia.
