大城市发展过程中经济、人口、空间相互作用力空间分异研究——以陕西西安为例

The Spatial Variation of Interaction Force Between Economy, Population and Space During the Development of Big City——Take Xi'an as Example

城市化的发展具有一定的时间规律和空间规律。大城市发展过程中,在城市经济、人口、空间相互作用力的推动下,城市不同区位具有各异的城市化发展特点。文章选取2004—2011年西安各区县的人口、经济、空间发展指标,通过对各指标增量之间的对比分析,得出以下结论:在经济发展对人口增加的推动作用中,核心城区由于人口饱和,人口对于经济发展的敏感性低于周边城区,远郊区受主城区极化作用的影响,人口敏感性低于离主城区更远的郊县;在经济发展对于空间建设的推动作用中,受整体房地产市场的影响,主城区和周边城区空间建设对于经济发展的敏感性整体高于郊县;在人口增长对于城市空间建设的推动作用中,核心城区由于人口饱和,空间建设对于人口增加的敏感性最高,其次是拥有开发区、大学城等有利条件的其他城区。

With the temporal and spatial characteristics of city development, The different location in the city has different urbanization characteristics under the promoting of interaction force between Economy, population and space during the development of big city. In this paper, quantitative analysis was introduced, and the interaction force between economy, population and space of each district in Xi＇an city were compared. At the base of that, the urbanization characteristics of each district were obtained, which would provide theory references for each district development strategy and promoting the coordinated development of the whole city＇s economy, population and space.
