【摘要】：针对中西方关于城市群空间扩展路径研究的争论,以京津冀城市群为例,运用夜间灯光数据,采取扩展强度指数、空间关联模型、多维驱动力分析模型,定量揭示了城市群时空扩展路径及其动力机制。结果表明:1 1992-2012年京津冀城市群时空扩展呈现以京津唐为核心的中心集聚扩展模式,保定—衡水—石家庄之间的"三角地带"成为城市群空间扩展的冷点区;2城市群空间扩展虽然已经出现了扩散势头,但向心集聚的惯性作用力依然强大;3城市群时空扩展的动力机制表现出以市场力为主要驱动因子的特征,行政力、外向力和内源力对城市群空间扩展的影响作用依次递减,从城市群空间扩展的驱动力演化趋势看,市场力、行政力、外向力的影响呈现上升趋势,而内源力的影响系数则呈现下降趋势。最后,提出降低行政干预、构建市场主导机制、强化内外双向开放、推动产业升级的政策建议,促进城市群空间结构持续优化。
[Abstract]:In view of the debate between China and the West on the spatial expansion path of urban agglomeration, taking the Beijing-Tianjin-Hebei urban agglomeration as an example, using night lighting data, the expansion intensity index, spatial correlation model and multi-dimensional driving force analysis model are adopted. The spatial and temporal expansion path and its dynamic mechanism of urban agglomeration are revealed quantitatively. The results show that the spatial and temporal expansion of Beijing-Tianjin-Hebei urban agglomeration from 1992 to 2012 presents a central agglomeration expansion model with the core of Beijing-Tianjin-Tang Dynasty. The "triangle zone" between Baoding, Hengshui and Shijiazhuang has become the cold spot of urban agglomeration spatial expansion. However, the momentum mechanism of spatial and temporal expansion of urban agglomeration is still powerful. The main driving factor is market power. The influence of administrative force, outward force and endogenous force on spatial expansion of urban agglomeration decreases in turn. From the trend of driving force evolution of urban agglomeration spatial expansion, the influence of market power, administrative power and extroversion force shows an upward trend, while the influence coefficient of endogenous force presents a downward trend. Finally, the paper puts forward the policy suggestions of reducing administrative intervention, constructing market leading mechanism, strengthening internal and external opening, promoting industrial upgrading, and promoting the continuous optimization of urban agglomeration spatial structure.
