摘　　要：在全球化、信息化、工业化、城镇化并行背景下,中国城镇体系的层级结构与流动网络相互交织、交互作用。论文基于改进的引力场模型以及空间计量模型,分析了城镇层级与人口流动(“层级—流”)交互下的武汉城市圈经济效能。研究发现:武汉城市圈城镇经济效能呈现显著的中心—外围格局,“武汉—鄂州—黄石—黄冈(武鄂黄黄)”经济高效能轴带初步形成。城镇经济总量会随着城市规模等级的提高实现超线性增长,但城镇经济规模以及效能差距有缩小趋势。人口跨尺度流动能促进城镇经济效能的增长,不同维度城镇层级对城镇经济效能的影响存在异质性。规模层级对城镇经济效能的影响是消极的,但大城市人口流的加剧能削弱规模不经济;功能层级对城镇经济效能具有促进作用,而且其能通过跨尺度人口流动进一步促进集聚经济;行政层级能促进城镇经济的高效能增长,高行政层级城镇人口流的加剧会促进层级扩散,进而在一定程度上削弱了行政层级的集聚效应。“层级—流”交互拓展了城镇经济增长的研究视角,深化了对不同层级单元经济高效能增长机理的认知,为都市圈城镇经济协调高效能发展奠定了基础。Under the background of globalization,informatization,industrialization,and urbanization,the hierarchical structure of China's urban system and its flow networks are intertwined and interact with each other.Based on the improved gravitational field model and the spatial econometric model,this study analyzed the economic efficiency of the Wuhan metropolitan area under the interaction of urban hierarchy and population flow(hierarchy-flow).The study found that the economic performance of cities and towns in the Wuhan metropolitan area showed a significant center-periphery pattern,and the Wuhan-Ezhou-Huangshi-Huanggang axis of economic efficiency is initially formed.The total economic volume of cities and towns grew super-linearly with the increase of urban population scale,but the gap between them tended to narrow.Population flows across scales promoted the growth of urban economic efficiency,and there was heterogeneity in the effects of different dimensions of urban hierarchies on urban economic efficiency.The influence of scale hierarchy on urban economic efficiency was negative,while increased population flows to large cities reduced scale diseconomies.Functional hierarchies contributed to the economic efficiency of cities and towns,and they further promoted agglomeration economies through cross-scale population flow.The administrative hierarchy promoted efficient economic growth in cities and towns,and growth in the scale of urban mobility at high administrative tiers promoted hierarchical diffusion.The interaction of hierarchy-flow expands the research perspectives of urban economic growth,deepens the understanding of the mechanism of high-efficiency growth of cities with different hierarchies,and lays the foundation for the coordinated and high-efficiency development of urban economy in metropolitan areas.
