摘　　要：研究城市空间结构及其影响因素对于推动城市高质量发展具有重要意义。以2007—2022年中国292个地级及以上城市为研究对象,基于夜间灯光数据计算赫芬达尔指数以表征城市空间结构,通过空间自相关研究其空间分异规律,建立双向固定效应的空间杜宾模型分析其影响因素。结果表明:研究期内全国和不同类型城市均呈现多中心演变趋势,且全局空间自相关性明显,局部空间自相关以高—低型和低—低型为主;空间杜宾模型回归结果显示,城市空间结构随着经济发展水平的提高呈现“先趋于单中心后趋于多中心”演化过程,物流通信基础设施发展推动城市空间结构向多中心演化,交通基础设施发展、产业结构高级化以及居民生活和消费水平提高有利于城市空间结构向单中心发展。Taking 292 cities at prefecture level and above in China from 2007 to 2022 as the research objects,this paper uses the nighttime light data to calculate the Herfindahl-Hirschman index(HHI)to characterize the urban spatial structure,reveals the spatial differentiation law of urban spatial structure through spatial autocorrelation,and constructs a spatial Durbin model with two-way fixed effect to analyze the influencing factors of urban spatial structure.It is found as follows.①During the study period,both the whole country and different types of cities showed a trend of polycentric spatial structure evolution.The global spatial autocorrelation of urban spatial structure was obvious,and the local spatial autocorrelation was mainly high-low clustering and low-low clustering.②The regression results of the spatial Durbin model showed that the urban spatial structure tended to be monocentric and then polycentric with the improvement of economic development level.The development of logistics and communication infrastructure promoted the evolution of a polycentric urban spatial structure.The development of transportation infrastructure,the upgrading of industrial structure and the improvement of residents′living and consumption levels were conducive to the formation of a monocentric urban spatial structure.
