摘　　要：临空经济区建设对推动产业结构升级、促进经济高质量增长至关重要。为探究城市发展对临空经济区的空间异质性影响,以全国51个国家级及地方临空经济区为研究对象,采用核密度分析法可视化并充分讨论了临空经济区发展的演化过程,同时构建了融合综合交通时间、航空运输业务水平等属性的复合邻近关系,在此基础上提出了基于多维距离的地理加权回归模型(MD-GWR),并以此对临空经济区发展的驱动因素进行建模,从而提出了促进各地区临空经济增长的差异化政策。研究表明:MD-GWR模型相比经典GWR模型拥有更优异的拟合精度,较经典GWR模型与OLS模型分别提升了12.52%与40.17%;城市经济体量、商业贸易、招商引资、企业规模、科技实力、产业结构对临空经济增长影响均存在显著的空间异质性,对不同地区的影响程度与方向具有较大差异;为推动临空经济区高质量发展,应进一步提升东北及西北地区城市的对外开放水平,提高东部地区城市的外商投资质量,完善东北及中西部地区城市的产业结构调整政策,加大乌鲁木齐、长春等城市的科技研发资金投入。研究结果有助于明确我国各城市临空经济区的发展规律与驱动机理,为制定具有针对性且差异化的临空经济区发展政策提供理论依据,对促进临空经济高质量增长具有重要意义。The construction of airport economic zones(AEZs)is crucial for promoting industrial structure upgrading and high-quality economic growth.To explore the spatial heterogeneity impact of urban development on AEZs,51 na-tional and local AEZs in China were selected as research objects.The kernel density analysis method was used to vis-ualize and fully discuss the evolution process of AEZ development.At the same time,a composite proximity relation-ship integrating comprehensive transportation time,air transportation service level,and other attributes was con-structed.Based on this,a multi-dimensional distance-based geographically weighted regression model(MD-GWR)was proposed,the driving factors of AEZ development were modeled,and differentiated policies to promote the growth of the airport economy in different regions were proposed based on the spatial heterogeneity of factors.The study shows:The MD-GWR model has better fitting performance compared to the classical GWR model,with im-provements of 12.52%and 40.17%,respectively,compared to the classical GWR model and OLS model;There is significant spatial heterogeneity in the impact of the urban economic scale,commercial trade,investment attraction,enterprise size,technological strength,and industrial structure on the growth of airport economy,with significant differences in the degree and direction of impact on different regions;To promote the high-quality development of the AEZ,it is necessary to further enhance the level of opening up of cities in the northeast and northwest regions,im-prove the quality of foreign investment in cities in the eastern region,improve the industrial structure adjustment pol-icies of cities in the northeast and central and western regions,and increase investment in scientific and technological research and development in cities such as Urumqi and Changchun.The research results are conducive to elucidate the development patterns and driving mechanisms of AEZs in various cities in China,provide a theoretical basis for formulating targeted an
