【摘要】 以兰西城市群作为研究对象，基于引力模型和城市首位度，结合各市现状，对研究区域内各个城市经济质量分类，进而分析城市群经济空间结构和其间的相互作用。结果表明，兰州市是兰西城市群重要的经济增长极；城市群内经济首位度排名较低的城市间联系较弱。目前兰西城市群面临单核城市群发展动力不足、城市群内资源错配和双核建设困难等问题。据此提出相应策略，为兰西城市群在区域协调发展新机制背景下的西北经济高质量发展提供参考。更多还原

【Abstract】 Taking the Lanzhou-Xining Urban Agglomeration as the research subject, based on the gravity model and urban primacy and in combination with the current situation of each city, the economic qualities of various cities within the area were classified. Then, the economic spatial structure and the interrelationships within the urban agglomeration were analyzed. The results show that Lanzhou City is an important economic growth pole. The connections among cities with lower economic primacy rankings within are weak. Currently, the urban agglomeration faces problems such as insufficient development momentum, resource misallocation, and difficulties in dual-core construction. Corresponding strategies are proposed to provide references for the high-quality economic development of the northwest region under the new mechanism of regional coordinated development.更多还原
