摘要: 以青岛市为例,利用CLCD数据集,通过GIS空间分析方法定量测度行政中心迁移前后青岛城市建设用地扩展的时空格局,分析行政中心迁移前后城市建设用地扩展的区域差异,并探讨城市行政中心迁移对城市空间扩展的作用机理。结果表明:1)行政中心迁移后,青岛建设用地面积扩展的数量、扩展速率、扩展强度的指标平均值均高于迁移前,即行政中心迁移加快了青岛城市建设用地的扩展速度;2)行政中心迁移带来了青岛城市空间扩展的集聚态势,表现出多中心集聚的变化趋势,环胶州湾沿线是空间扩展的主要热点区;3)土地财政是青岛行政中心迁移后城市空间扩展的直接原因,土地财政的提升提高了政府的空间治理能力,进一步推动青岛市生产要素、城市规划和城市功能的重构,间接影响了城市的空间扩展。本研究凸显了在城市规划和发展战略中考虑行政中心迁移的空间影响的重要性,能为城市行政中心的科学迁移和规划未来城市发展方向提供参考。

Abstract: The administrative center is a core element in the framework of administrative division research. The location, adjustment, and change of a city’s administrative center can significantly impact the spatial form and structure of the city. This paper takes Qingdao City as a case study and utilizes the CLCD dataset, along with GIS spatial analysis methods, to quantitatively measure the spatial and temporal patterns of urban construction land expansion after the relocation of the administrative center. It analyzes the differences in urban built-up area spatial expansion before and after the relocation and explores the mechanisms of how the relocation of the administrative center influences urban spatial expansion. The results show that:1) After relocating the administrative center, Qingdao’s construction land area exhibits higher average values for the number, rate, and intensity of expansion compared to before relocation, indicating that the relocation of the administrative center accelerates urban construction land expansion in Qingdao; 2) The relocation of the administrative center has led to an agglomeration trend in Qingdao’s urban spatial expansion, with a shift towards polycentric agglomeration, and the primary hotspot of spatial expansion lies along the Jiaozhou Bay Ring; 3) Land finance is the direct cause of urban spatial expansion following the relocation of Qingdao’s administrative center. The strengthening of land finance enhances the spatial governance capacity of the government, further promoting the reconfiguration of production factors, urban planning, and urban functions in Qingdao. As a result, this process indirectly influences the city’s spatial expansion. The findings of this study emphasize the significance of incorporating the spatial impact of administrative center relocation into urban planning and development strategies. These findings can serve as a reference for the strategic relocation of urban administrative centers and the planning of future urban development directions.
