【摘要】：以广州市近16年的面板数据为基础,构建适用于城市化后终期阶段的综合评价指标体系,运用熵值法对广州市城市化综合水平进行测度,并分析其演变特征及驱动力.结果表明:(1)城市化进入后终期阶段,经济城镇化和社会城镇化成为广州城市化的主要推动力,其次是人口城市化,最后是空间城市化.社会城市化水平的提高,表明城市化质量逐步提升.广州限制与压缩城市人口规模是引起人口城市化呈现平缓增长趋势的主要因素;(2)工业化已不是推动城市化发展的直接动力,交通外延成为推动空间城市化的主要因素.第一产业对经济城市化无推动作用,相比第二产业,第三产业对经济城市化的贡献更为显著,且已成为经济城市化发展的后续动力.外商投资对经济城市化的促进作用已逐步衰弱,而内生性作用成为推动城市化的主导因素;(3)城市建成区的外延拓展趋于放缓,土地城镇化由粗放式的农业地域向城市地域转化向城市内部地域土地集约化转变.本文认为,对于进入城市化后终期阶段的城市,应加快第三产业发展,减缓城市建成区扩张速度,注重城市内部地域土地集约化,优化城市内部功能分区,提升城市化质量.
[Abstract]:Based on the panel data of Guangzhou in the past 16 years, a comprehensive evaluation index system suitable for the final stage of urbanization is constructed. The comprehensive level of urbanization in Guangzhou is measured by entropy method, and its evolution characteristics and driving forces are analyzed. The results show that: (1) after urbanization enters the final stage, economic urbanization and social urbanization become the main driving force of Guangzhou urbanization, followed by population urbanization, and finally spatial urbanization. The improvement of the level of social urbanization indicates that the quality of urbanization is gradually improving. Guangzhou limits and compresses the urban population scale is the main factor which causes the population urbanization to present the gentle growth trend; (2) the industrialization is not the direct motive force which impels the urbanization development, the traffic extension becomes the main factor which impels the spatial urbanization. Compared with the secondary industry, the tertiary industry has a more significant contribution to the economic urbanization, and has become the follow-up power of the economic urbanization. The promotion of foreign investment to economic urbanization has gradually weakened, and the endogenous role has become the leading factor to promote urbanization; (3) the extension of the urban built-up area tends to slow down, and the urbanization of the land changes from the extensive agricultural region to the urban area to the intensive transformation of the urban internal region. This paper holds that for the cities entering the final stage of urbanization, we should speed up the development of the tertiary industry, slow down the expansion of urban built-up areas, pay attention to the intensification of land in urban areas, optimize the functional zoning of urban interior, and improve the quality of urbanization.
