摘要
研究运用哈肯模型、空间引力模型和空间关联模型,对2013—2022年兰西城市群9个城市科技创新驱动因素分析与空间关联特征进行分析。研究结果表明:(1)人工智能数量、科学研究从业人员、专任高校教师数、互联网宽带接入用户数和绿色专利申请量等创新驱动因素对兰西城市群科技创新能力具有显著正向驱动作用。(2)兰西城市群内部城市的科技资源流动呈现出“双核驱动、分层发展”的空间格局特征,但跨省域城市间的引力系数普遍偏低,兰州市与西宁市2个核心城市间的引力系数仅为0.183。(3)兰州市和西宁市空间分布特征呈现出HL集聚模式,表明两个城市科技创新水平相对较高,而城市群内其他城市的创新水平相对较低。
This study employs the Haken model,spatial gravity model,and spatial correlation model to analyze the driving factors of technological innovation and spatial correlation characteristics of 9 cities in the Lanzhou-Xining City Cluster from 2013 to 2022.The research findings indicate that:(1)Innovation driving factors such as the number of artificial intelligence applications,scientific research personnel,full-time university teachers,broadband internet users,and green patent applications have significant positive driving effects on the technological innovation capacity of the Lanzhou-Xining City Cluster.(2)The flow of technological resources within the Lanzhou-Xining City Cluster exhibits a spatial pattern characterized by"dual-core driven,hierarchical development,"but the gravity coefficients between cross-provincial cities are generally low,with the gravity coefficient between the two core cities of Lanzhou and Xining being only 0.183.(3)The spatial distribution characteristics of Lanzhou and Xining show an HL agglomeration pattern,indicating that these two cities have relatively high levels of technological innovation,while other cities in the cluster have relatively lower innovation levels.
