摘　　要：[目的]在黄河流域生态保护和高质量发展成为重大国家战略、黄河流域甘肃段作为甘肃省国土空间格局优化主体的时代背景下,从经济视角探索区域城镇空间结构的内在属性以提高黄河流域甘肃段总体发展水平。[方法]借助引力模型、区位商指数及地理探测器分别从城镇经济联系网络结构、城镇竞争优势结构、产业集聚结构3个方面对黄河流域甘肃段城镇经济空间结构的演变特征、动因进行探讨。[结果]区域经济联系网络水平和城镇竞争优势水平均逐步提升,其结构由单中心簇型向多中心簇型演进,第一产业集聚结构经历了“全局型结构—穿孔型结构”演变过程,第二产业集聚结构为穿孔型结构,且该结构逐步增强,第三产业集聚结构经历了“穿孔型结构—局部型结构—穿孔型结构”的演变过程;黄河流域甘肃段城镇竞争优势与地方政府财政收入关系密切,相应产业产值占比越高产业发展越集聚,此外受生态保护、供给侧结构性改革的影响,已经开始走去工业化及工业转型道路,固定资产投资和政府财政支出在发展第二产业上的投入占比将下降。[Objective]Against the background of ecological conservation and quality development of the Yellow River ba⁃sin recognized as a major national strategy and of Gansu section of the River basin as the major part of land spatial optimi⁃zation in Gansu province,we explore the intrinsic traits of the regional urban spaces from economic perspectives so as to advise on the approach to improve the overall development of the Gansu section of the Yellow River basin.[Method]Adopting gravity model,location quotient and geodetector,we explore the evolution of the urban economic spatial evolu⁃tion in Gansu section of the Yellow River basin and its causes from the urban economic connection network,the structure of urban competitive edges, and the industrial cluster structure respectively.[Result]Both the networking level of re⁃gional economic connections and the level of urban competitive edges have been gradually promoted, and its structurehas been transformed from monocentric cluster to polycentric cluster;the first industrial cluster has undergone a transfor⁃mation from global structure to perforated one, and the second industrial cluster ends up a perforated structure which isincreasingly strengthened, and the third industrial cluster has undergone an evolution process from perforated structureto local and then to perforated one. Urban competitive edges of the Gansu section of the River basin are closely related tolocal governments' revenues, and the higher the corresponding industrial production values, the more clustered the in⁃dustrial developments;moreover, affected by ecological conservation and supply-side structural reform, it has begun ajourney of deindustrialization and industrial transformation, and fixed-asset investment in and government fiscal expendi⁃ture on the second industry will decrease in its percentage.
