摘　　要：丝绸之路经济带建设是在新全球经济、政治格局下所提出的战略构想。本文从产业分工角度对引力模型加以改进,并结合社会网络分析法,对丝绸之路经济带城市经济联系特征等作以实证分析,同时考察经济距离变动所带来的影响。研究发现:经济距离是影响城市经济联系的主要因素;经济带各节点城市对外经济联系总量逐年提高,但其经济联系具有较大的不对称性;经济带的集中趋势较低,存在核心——边缘结构。合理化产业布局、保证轴线畅通及提升城市产业专业化水平对经济带建设具有积极意义。The construction of Silk Road economic belt is proposed in new political and economic structure. Making improvement on gravity model from the perspective of industrial division, combining social network analysis and considering the influence of the change of e- conomic distance, this paper analyzes the feature of urban economic ties on the Silk Road economic belt. The results show that： economic distance is the dominant factor influencing urban economic ties. The aggregate of foreign economic relation in each node city on the economic belt increases year by year, however its economic relation is severely asymmetric. Core peripheral structure shows that centralized tendency on the economic belt is low. Rationalizing industrial distribution, ensuring smooth axis and promoting urban industry specialization level will play a positive effect on the construction of the economic belt.
