首发时间:2014-07-18
摘要:"丝绸之路经济带"的建设与发展是目前的热点话题。本研究分别选取"丝绸之路经济带"上中国段(省级尺度)9个省份及国家尺度18个国家(含中国),以各个国家及地区间的经济联系为实证,运用社会网络分析方法,分别构建了"丝绸之路经济带"中国段各地区(省级尺度)经济联系网络及"丝绸之路经济带"国家尺度之间的经济联系网络,对两个网络分别制作了可视化结构图,并进行了网络密度、中心性、凝聚子群及核心边缘结构的计算,进而对网络特性进行了分析。结果显示两个网络均为低密度网络,经济联系网络围绕主要国家及地区展开,呈现了一定的不均衡性,形成了相互作用的凝聚子群,网络核心边缘结构突出,最后提出了关于"丝绸之路经济带"经济联系网络结构提升的相关政策建议。

The Quantitative Structural Measurements of Economic Ties Networks of the Silk Road Economic Belt Based on SNA
Abstract:Nowadays, the construction and development of Silk Road Economic Belt have been a hot topic. This paper chooses 9 provinces of China and 18 countries (including China) along the belt to construct two networks based on the economic ties between the various regions (provincial scale) within China and between the various countries by applying the social network analysis, respectively. We also calculate the network density, centrality, cohesive subgroup and core-periphery structure to analyze the network characteristics. The results demonstrate that both networks are low density network. Besides, the economic ties networks of major countries and regions show some imbalance and form interactive cohesive subgroups. Particularly, these networks have remarkable core-periphery structure. Finally, we propose some policy suggestions about the promotion of economic ties networks of Silk Road Economic Belt.
Keywords: Economic Geography Silk Road Economic Belt Social Network Analysis
