摘　　要：以丝绸之路经济带暨第二亚欧大陆桥沿线的我国境内西北地区城市群为研究对象,构建城市综合竞争力指标,运用修正的引力模型、隶属度模型及潜力模型等对西北地区城市群空间联系特征进行实证分析,得出结论:伴随该区域城市群的迅速发育,城市间最短时间距离缩短,通达性大为改观;城市群城市空间联系强度水平较差,空间分异呈由东向西逐渐递减的趋势,受最短时间距离影响明显;城市群内城市受其中心城市的辐射带动作用不足;西北地区城市群潜力值整体呈东西两头好、中间凹陷的"哑铃型"状态,各城市群内城市集聚能力差异明显。Under the International strategic background of ‘the Silk Road Economic Belt and the 21 st-Century Maritime Silk Road＇, RMB became a member of ‘Special Drawing Rights currency basket＇ that is benefit for China extremely. Asian Infrastructure Investment Bank will be operated before the end of this year. The Silk Road project investment fund also has been carried out. The interest community of ‘the Belt and Road＇ is con- tinuously growing bigger. The governments of member states of the Shanghai Cooperation Organization are also making great effort to promote their development strategies docked with the land and maritime Silk Road initiative, to further advance International cooperation and to swift score greater collaborative develop- ment.Establishing the city comprehensive competitiveness index system, and analyzing the connection be- tween different cities in northwest China by adopting the improved gravity model, subordination degree mod- el and potential model, our research concludes that： with the rapid development of the city groups in this ar- ea, the shortest distance time between cities has shorten a lot, and the accessibility also has improved much; decreasing from the east to the west which is effected obviously by the shortest distance time, the level of spatial connection among different cities is low; the cities in the city groups are insufficiently radiated by the core city; the potential value of urban agglomerations in five northwestern provinces emerges a dumbbell- shaped state that the two ends are better than the middle, while the gathering ability of each city in the city groups is different noticeably.
