成渝城市群要素特征研究
|
摘要
通过对成渝城市群人口数据、城镇化率、城市规模、地区生产总值和三次产业数据进行处理,运用对比分析方法和可视化技术分析,发现成渝城市群城镇人口主要集中在成都市和重庆市主城区,核心城市极化作用过强,城市间发展差距大;城市群城镇化率低,缺少Ⅰ型大城市;经济呈现东高西低,发展不平衡,产业主要以第二产业为主等特点。结合前沿理论与成渝城市群实际情况,认为成渝城市群应加强内部的协同作用,促进区域的协调发展;重庆市主城区和成都市的极化作用应逐步向扩散作用转化,积极引导核心城市进行产业疏散,增强核心城市的辐射带动功能,完善城市群的城市规模结构。
Through processing the population data, urbanization rate, urban size, gross regional domestic production and tertiary industry data of Chengdu-Chongqing Urban Agglomeration, and applying comparative analysis method and visual technological analysis, it was found that the urban population of Chengdu-Chongqing Urban Agglomeration was mainly concentrated in the main urban areas in Chengdu and Chongqing. The polarization effect of core cities was too strong, as a result, the gap between cities was large; the urbanization rate of urban agglomeration was low and there was no Type I major cities; the economic development was unbalanced, high in the East and low in the West, with the secondary industry as the main part. Combining with the leading theories and the status quo of Chengdu-Chongqing Urban Agglomeration, the internal synergy of Chengdu-Chongqing Urban Agglomeration should be strengthened to promote the coordinated regional development; the polarization effect of Chengdu and Chongqing's main urban areas should be gradually transformed into diffusion effect to improve the urban scale of the urban agglomeration through actively encouraging the core cities to conduct industrial evacuation and enhance their radiation-driven function.
