珠三角城市群内部空间相互作用研究

The Research of Spatial Interaction among Pearl River Delta Cities

城市群的概念近来引起热议,对城市群内部空间结构的探寻对于科学制定城市群发展战略具有重要意义。本文以珠三角城市群作为研究案例,基于主成分模型,选用指标体系对珠三角城市群的城市综合规模进行定量测定,同时结合场强模型划分了珠三角内九大城市腹地范围。结果显示珠三角城市群当前仍旧存在区域内城市发展不平衡的状况,广州深圳双城独大的状况仍旧在未来较长一段时间内持续下去。同时结合腹地面积与行政区面积的分析认为,腹地面积更多取决于城市的发展实力与城市的区位,城市决策者在制定城市发展策略时应该从区域视角出发而非止步于行政区的限制。

Urban agglomeration is a concept of heated debate. Exploring the spatial structure of the urban agglomeration is crucial for policy making. Taking Pearl River Delta as an example and based on the principal component analysis, the author calculates the comprehensive strength of nine cities. Also calculated is the cities＇ hinterland range based on a field strength model. Results suggest unbalanced urban development in the Pearl River Delta, with Guangzhou and Shenzhen being the two super powers in the region for a long time to come. It is also found that a city＇s hinterland range depends much on its comprehensive strength and location. Therefore, when making urban development strategies, policy makers should consider the whole region instead of being constrained by the administrative boundaries.
