丝绸之路经济带建设的一个重要前提是把握沿线产业结构的空间差异。文章基于此，运用区位熵灰色关联分析，测度丝绸之路经济带西北段主要节点城市的产业结构与分工程度的空间差异。结果表明：丝绸之路经济带西北段各城市的产业结构总体相似性较大，区域分工差异性较小，差异化产业发展思路尚未形成，同质性竞争较为激烈。最后，建议丝绸之路经济带西北段各个城市应该走差异化发展道路，形成“合力”优势，发挥“拳头”作用。%One must understand the spatial differences of the industrial structure along the Silk Road before one can study the development of the Silk Road Economic Belt. By applying the Gray Correlative Analysis to measure the in-dustrial structure and the space differences of the degree of division about the major cities in northwestern China, this paper found that the industrial structure of the cities is similar on the whole, regional division of labor has a little dif-ference, differentiated industrial development has not yet been formed, and homogeneous competition is more in-tense. It proposed that the cities along the Silk Road Economic Belt should highlight their uniqueness in their eco-nomic development to exert the knockout function by forming their“joint”advantages.
