基于指标追踪的天津市半城市化区县发展历程及机制研究

摘要:
作为京津冀典型特大城市之一,天津市从2000年开始进入快速空间扩张时期,市郊区县也相继进入半城市化阶段,其发展历程及城镇化驱动机制在京津冀都市圈具有较强的典型性,且与长三角珠三角城市发展差异较大。本文在既有半城市化发展历程定量化研究的基础上,优化指标体系,提出基于指标追踪的门槛时间划定方法和发展模式分析方法,并应用于天津市半城市化区县,分析结果显示:天津市半城市化空间扩张经历了轴向拓展-圈层化扩张-中郊蔓延-外向衰减四大发展阶段;近远郊发展模式差异性较强,其中近郊以土地-综合-人口的快速迭代增长模式为主,中远郊则以土地-人口(经济)的缓慢波动发展模式为主。最后,结合分析结果和实际发展路径对其发展机制及治理瓶颈进行分析。

Research on the Development History and Mechanism of peri-urbanized Areas in Tianjin Based on Indicator Tracking

Abstract:
As one of the typical mega cities in Beijing-Tianjin-Hebei metropolitan area, Tianjin has entered a period of rapid space expansion since 2000. And suburban counties have also entered the peri-urbanization stage. Their development history and urbanization drive mechanism have strong typicality in the Beijing-Tianjin-Hebei metropolitan area and are different from the development of the Yangtze River Delta and the Pearl River Delta metropolitan area. Based on the quantitative research of the development process of peri-urbanization, this paper optimizes the index system, proposes the threshold time-based method and development mode analysis method based on indicator tracking, and applies it to the peri-urbanized districts of Tianjin. The results show that the expansion of the peri-urbanization space in Tianjin has experienced four major development stages: axial expansion-circle expansion-suburban spread-external attenuation; the development pattern of the near-outer suburbs is strong. the suburbs are the ‘land-integrated-population’ rapid iterative growth model, while the middle and outer suburbs are dominated by the slow-floating development model of land-population (economic). Finally, the development mechanism and difficulties in governance are analyzed based on the analysis results and the actual development path.
