基于社会网络分析的丝绸之路经济带区域经济研究——以兰新铁路沿线城市为例

Research on the Regional Economy along the Silk-Road Economic Belt Based on Social Network Analysis:Taking the Cities Along Lanzhan-Xinjiang High-Speed Railway for Example

基于点轴布局理论和引力模型理论,以兰新铁路为着眼点选取了甘肃与新疆地区9个沿线城市进行研究,计算了丝绸之路经济带局部城市间的经济联系值,采用社会网络分析法研究区域经济联系结构。结果表明,兰新铁路沿线主要城市经济联系程度一般,区域经济联系呈现不均衡现象,网络中存在6个联系密度较低的凝聚子群,城市间的经济联系仍需进一步加强。根据兰新铁路沿线经济发展现状,提出相关政策建议促进丝绸之路经济带区域经济发展。

Based on Pole-axis theory, this paper selects the I.anzhou-Xinjiang High-speed Railway as the line of research, studies nine cities of Gansu and Xinjiang province and calculates the value of economic relations among cities drawn on the idea of gravity model, and analyses the economic structure using social network analysis method. The result shows that the degree of economic contacts among cities along the railway is ordinary, and economic contacts appear unbalance. There are six small groups with low density, thus it is necessary to enhance the economic relations among major cities. Finally, some policies and suggestions to promote the development of regional economy along the Silk Road Belt according to its economic condition are put forward.
