摘　　要：城市群空间结构是提升城市群功能的重要抓手。在新经济地理学框架下,以双行业三城市结构城市群为例,进行了城市群空间结构演变与功能提升的理论分析。结果显示,在双行业三城市结构城市群中,行业1和行业2在城市群中的空间配置具有不同规律,与行业的产品替代弹性和居民消费份额中行业消费份额密切相关,这决定了行业能否分散到新的区位上形成新城市,发生城市群空间结构演变。基于这一规律进行城市群产业分工深化,将实现城市群空间结构由集聚极化演变为平衡发展,提升城市群承载经济和人口功能。因此,提升城市群承载经济和人口功能需要促进城市群各专业化城市的形成,提高城市群各城市间产业梯度分工程度。加强城市群内运输系统建设,促进产业集聚与扩散,有助于保障产业分工格局的形成。The spatial structure of city clusters serves as a crucial lever for enhancing their function.Under the framework of new economic geography,this study conducts a theoretical analysis of spatial structure evolution and functional enhancement in city clusters,using the city clusters with a dual-industry and three-city structure as a case study.The results reveal distinct spatial allocation patterns between Industry 1 and Industry 2 within such city clusters.These patterns are closely tied to the product substitution elasticity of the industry and the proportion of industry consumption in the proportion of residents'consumption,which determine whether industries can decentralize to new locations to form a new city,thereby driving the evolution of the spatial structure of city clusters.Based on this law,the deepening of the industrial division of labor in city clusters will realize the transformation of city clusters'spatial structure from centralized polarization to balanced development,ultimately enhancing their capacity to support economic and population functions.Therefore,improving city clusters'economic and demographic carrying capacity requires promoting the formation of specialized cities within the city clusters and strengthening the degree of industrial gradient division of labor among cities in city clusters.In addition,strengthening the construction of transportation systems within city clusters and promoting the agglomeration and diffusion of industries will ensure the formation of the industrial division pattern.
