县域经济格局的空间联系与空间结构：基于兰西城市群的实证分析
|
摘要
论文基于兰州—西宁城市群31个县级区域数据,通过熵值法计算县域经济综合质量,采用改进的引力模型与社会网络分析方法,测算县域经济格局的空间联系以及识别空间结构特征。结果表明,兰州—西宁城市群的经济空间联系整体处在较低水平,空间分布不均衡;县级城镇存在显著的等级分布特征,经济空间联系水平呈现出由核心区域向周边区域梯度递减态势;城市群在空间上表现为显著的三级圈层结构,第二圈层内县域城市的桥梁中介作用不足;城市群内经济空间联系的集聚效应强于涓滴效应。对于中国县域经济空间问题,论文给出的研究方法和研究结论具有重要学术价值和实践意义。
Based on the 31 county-level regional data of Lanzhou-Xining city group, the paper calculates the comprehensive quality of county economy by entropy method, and uses the improved gravity model and social network analysis method to measure the spatial relationship of county economy and identify the spatial structure characteristics. The results show that the economic spatial relationship between Lanzhou and Xining city groups is at a low level and the spatial distribution is uneven. The county cities have significant hierarchical distribution characteristics, and the economic spatial connection level shows a gradient from the core region to the surrounding region. The city group appears as a significant three-level circle structure in space, and the bridge mediation effect of county cities in the second circle is insufficient; the agglomeration effect of economic space connection within the city group is stronger than the trickle effect. For the study of China's county economic space, the research methods and research conclusions of this paper have important academic and practical significance.
