摘　　要：推动城市群形成合理有序的空间结构,发挥中心城市的辐射作用,是释放国内消费潜力的有效手段。基于新经济地理学建模思想,本文构建用于分析中心城市极化对城市群消费潜力影响的理论模型,选取十大城市群内170个城市作为研究对象,对城市群中心城市极化程度与城市群消费潜力间的作用机制进行实证检验。研究发现:城市群空间极化结构通过产业布局的横向和纵向效应促进消费潜力的释放,且中心城市存在一个最优产业结构,而无序的产业集聚不利于整体需求增加;削减交易成本、促进劳动力流入作为间接影响机制,能够促使中心城市拉动城市群消费潜力;中心城市定位与城市群发展阶段也会影响消费潜力释放。中心城市的极化程度影响城市群内部分工结构与资源配置效率,进而反映在产业和劳动力需求扩张上。因此,培育城市群中心城市向超大、特大城市成长,优化产业结构,完善基础设施,提高产品和要素的流通效率,都有助于释放城市群的消费潜力。Promoting the formation of a rational and orderly spatial structure of urban agglomerations and giving play to the catalytic role of central cities are effective means of releasing domestic consumption potential.Based on the modeling idea of new economic geography,a theoretical model is constructed to analyze the impact of central city polarization on the consumption potential of urban agglomerations,and 170 cities within the ten major urban agglomerations are selected as the research objects to empirically test the mechanism between the degree of polarization of the central city of urban agglomerations and the con⁃sumption potential of urban agglomerations.The study finds that the spatial polarization structure of urban agglomerations promotes the release of consumption potential through the horizontal and vertical effects of industrial layout,and there exists an optimal industrial structure in the central city,while the disorderly industrial agglomeration is not conducive to the increase of the overall demand.The reduction of transac⁃tion costs and the promotion of labor inflow as an indirect influence mechanism can prompt the central city to form a pull on the consumption potential of the urban agglomerations,and the positioning of the central city and the stage of development of the urban agglomerations can also affect the release of consumption po⁃tential.The positioning of the central city and the development stage of the urban agglomeration will also affect the release of consumption potential.The degree of polarization of the central city affects the division of labor structure and resource allocation efficiency within the urban agglomeration,which in turn is reflec⁃ted in the expansion of industrial and labor demand.Therefore,fostering the growth of central cities in ur⁃ban agglomerations into mega-cities,optimizing the industrial structure,improving the infrastructure,and enhancing the efficiency of product and factor circulation will all help release the consumption potential of urban agglome
