黄河流域城市群高质量发展评估与空间格局分异

城市群是黄河流域高质量发展的主要载体,黄河流域的高质量发展重点取决于城市群的发展质量及辐射带动作用。通过构建城市群高质量发展评价指标体系,从创新、协调、绿色、开放、共享五个维度对2016年黄河流域7个城市群及内部所有地级城市进行高质量发展评估,研究发现:①黄河流域城市群高质量发展水平空间差异显著,中下游的城市群高质量发展指数高于中上游城市群;②黄河流域城市群高质量发展空间格局中存在"中部塌陷",处于中部地区的中原和晋中城市群多个维度上低于东西部城市群;③城市群内部城市的高质量发展水平呈现明显的"中心-外围"格局,核心城市高质量发展水平显著高于外围城市;④行政等级高和区位条件好的城市往往拥有较高的高质量发展水平,受所处黄河位置的影响并不显著。研究认为,黄河流域城市群应该加强核心城市对城市群整体的辐射带动作用,通过城市群整体的高质量发展影响带动整个黄河流域的高质量发展。

High-Quality Development Assessment and Spatial Heterogeneity of Urban Agglomeration in the Yellow River Basin

Urban agglomeration is the main carrier of the high-quality development of the Yellow River basin.The highquality development of the Yellow River basin depends on the development quality of urban agglomeration and its driving effect.By building the evaluation index system of high-quality development of urban agglomerations,the study assessed the development quality of the 7 urban agglomerations and internal cities in Yellow River basin in 2016 from five dimensions as innovation,coordination,green,open and sharing,the study found that:1)There are significant spatial differences in the development quality level of urban agglomerations in the Yellow River basin,the high-quality development indexes of the middle and lower reaches of urban agglomerations are higher than that of the middle and upper reaches;2)The spatial pattern of high-quality development of urban agglomerations in the Yellow River basin is shown as"central collapse",the development indexes of Zhongyuan urban agglomeration and Jinzhong urban agglomeration in the central region are lower than the urban agglomerations of east and west in many dimensions;3)The high-quality development level of the inner cities presents an obvious pattern of"central-peripheral",the high-quality development level of the core cities is significantly higher than that of the peripheral cities;4)The city with higher grade and the better location often has higher development quality level,which is not significantly affected by the location of the Yellow River.According to the study,the urban agglomerations in the Yellow River basin should strengthen the radiative driving effect of core cities on the whole urban agglomeration,and drive the high-quality development of the whole Yellow River basin through the high-quality development of urban agglomerations.
