复合生态系统下城市高质量发展时空演化及驱动因素研究——以黄河流域7大城市群为例

基于复合生态系统理论,构建高质量发展评价体系,考察了2010—2018年黄河流域城市群高质量发展时空演化特征与驱动因素,结果表明：①城市群高质量发展呈“下游领先、中游振兴、上游落后”的空间特征,经济发展水平与社会民生低下是首要制约因素。②高质量发展水平趋于收敛,但区域差异显著,资源环境促进高质量发展趋同。③高质量发展耦合逐年攀升,协调度下降趋势明显,东西非均衡化特征突出。④高质量发展的空间差异性由多因子共同作用,其中科技创新是核心驱动因子。

SPATIOTEMPORAL EVOLUTION AND DRIVING FACTORS OF URBAN QUALITY DEVELOPMENT IN A COMPLEX ECOSYSTEM: TAKING THE SEVEN MAJOR URBAN AGGLOMERATIONS ALONG THE YELLOW RIVER BASIN AS EXAMPLES

To coordinate the economic development, resources and environment as well as the coordinated development of people's livelihood in urban agglomerations along the Yellow River Basin is not only the practical need to steadily promote the overall strategic layout of "five-in-one", but also the key to fully implement the new development concept. Based on the theory of complex ecosystem, this paper constructed a high-quality development evaluation system, and explored the spatial differentiation and driving factors of high-quality development of urban agglomerations in the Yellow River Basin from 2010-2018 by using the entropy weight TOPSIS method, coupled coordination degree model and geographical probe. The results show that:1) The high-quality development of urban agglomerations have the spatial characteristics of "leading in the lower reaches, revitalizing in the middle reaches and lagging in the upper reaches", and social livelihood of the people is the primary limiting factor. 2) The level of high-quality development tends to converge, but regional differences are significant. Resources and environment promote the convergence of high-quality development. 3) The coupling of high-quality development increases year by year, the degree of coordination decreases obviously, and the characteristics of East-West imbalance are prominent. 4) The spatial differences of high-quality development are caused by multiple factors, among which scientific and technological innovation is the core driving factor.
