摘　　要：在城乡融合发展对城乡空间布局提出更高要求的背景下,探讨市域城镇空间结构的演变特征和演变机理具有重要意义。本文在CP模型的基础上,尝试融入技术变革和消费升级的现实背景,推演市域城镇空间结构演变特征。随后采用2017—2021年中国270个地级市及其下辖19064个乡镇的面板数据,分别从微观与宏观角度进行验证。研究发现,理论上,交通与通信能力、地域特有要素和地理区位共同促使市域城镇空间形成多级并存的“小集聚、大分散”结构;实证上,部分乡镇单元己在区位、交通与通信能力及特有要素影响下实现人口集聚,农业、服务业特有要素、交通能力与地理区位相互作用,正推动市域城镇空间向“小集聚、大分散”模式演变。In the context of urban-rural integration development,which demands an optimized spatial layout,exploring the evolution characteristics and mechanisms of urban spatial structure is crucial.This paper adopts the core-periphery model from new economic geography to analyze the impact of advancements in transportation and communication technologies,alongside shifts in consumer behavior.We deduce the evolution patterns of urban spatial structure by examining panel data from 270 prefecture-level cities and 19064 townships from 2017 to 2021.Our empirical analysis investigates two dimensions:micromechanisms and macro-effects.Theoretically,we find that urban spaces are shaped by the interplay of transportation and communication advancements,regional specific factors,and natural geographical location,leading to a spatial structure characterized by"small agglomeration and large dispersion"where various urban units coexist.Empirically,certain townships have experienced population growth due to the combined effects of geographical location,transportation and communication levels,and specific regional factors.Overall,urban spaces are evolving towards a structure defined by"small agglomeration and large dispersion"influenced by agricultural and service industry factors,transportation accessibility,and actual geographical distances.
