| 摘 要： | 以中国“十三五”规划纲要提及的19个城市群为研究对象,从创新、协调、绿色、开放和共享5个维度构建中国城市群高质量发展综合评价指标体系,运用熵值法、地理探测器等研究方法,剖析2006—2018年中国城市群高质量发展的时空格局特征及其分异机理。结果表明：① 总体来看,中国城市群高质量发展水平呈增长态势,各维度发展水平与发展速度存在差异。② 从空间格局看,总体保持“东中西”梯度递减格局,但随着中、西部部分城市群高质量发展水平稳步上升,空间梯度格局呈减弱趋势。③ 从空间集聚特征看,城市群高质量发展集聚态势逐渐增强,集聚类型中HH型主要集中在珠三角、长三角城市群;HL型出现在各城市群的核心省会城市;LH型主要位于长三角城市群高值集聚地区的周边城市;LL型主要位于成长早期与初级阶段城市群的交界处。④ 从探测因子作用力强度看,“十三五”规划中期各因子作用强度排序为收入水平、人口密度、教育水平、政府调控和投资强度。其中,投资强度作用力于“十二五”时期下滑趋势明显,说明城市群高质量发展依赖投资驱动的作用减弱。此外,不同发育阶段的城市群高质量发展的主导因素在不同时期也发生变化。⑤ 针对不同发育阶段城市群应因“群”施策。成熟阶段城市群应注重收入水平、政府宏观调控及人口集聚的重要作用,成长阶段城市群需提高收入水平,重视教育水平的提升,同时加强投资具有分工潜力的产业或产业链。

| Abstract: | This article takes the 19 urban agglomerations mentioned in the outline of China's 13th Five-Year Plan (2016-2020) as research objects, and constructs a comprehensive evaluation index system for high-quality development of urban agglomerations in China from five dimensions of innovation, coordination, green, openness and sharing. Research methods such as entropy method and geographic detector model are used to analyze the spatiotemporal characteristics and differentiation mechanism of high-quality development of China's urban agglomerations from 2006 to 2018. The results show that: (1) From the perspective of the overall development level, the high-quality development level of China's urban agglomerations shows an increasing trend, and there are differences in the development level and speed of each dimension. (2) From the perspective of spatial distribution, an overall pattern of decline from the eastern to the central and western regions remains stable, but with a steady rise of high-quality development level of some urban agglomerations in central and western China, and the spatial gradient pattern shows a weakening trend. (3) From the perspective of spatial characteristics, the agglomeration trend of high-quality development of Chinese urban agglomerations is gradually increasing. Among the agglomeration types, the HH type is mainly concentrated in the Pearl River Delta and Yangtze River Delta urban agglomerations; The HL type appears in core provincial capital cities of each urban agglomeration; The LH type is mainly found in the surrounding cities of the high-value agglomeration area of the Yangtze River Delta urban agglomeration; The LL type is mainly at the junction of urban agglomerations in the infant and primary growth stages. (4) From the perspective of the force intensity of the detection factors, in the middle period of the 13th Five-Year Plan, the intensity of each factor in descending order is income level, population density, education level, government regulation, investment intensity. Among them, the force of investment intensity declined significantly during the "12th Five-Year Plan" period (2011-2015), indicating that the role of high-quality development of urban agglomeration driven by investment has weakened. In addition, the leading factors of high-quality development of urban agglomerations in different development stages changed in different periods. (5) In view of the differences in differentiation mechanism of urban agglomerations at different development stages, corresponding countermeasures should be implemented according to different conditions of urban agglomerations. Urban agglomerations in the mature stage should focus on income improvement, government macro-regulation and population agglomeration; It is important not only to raise income but also to enhance education level and investment in industries or industrial chains with the potential for division of labor during the growth stage. |
