摘　　要：文章通过构建时间跨度为2015—2021年的非平衡短面板数据,讨论成渝地区双城经济圈内各市(区县)到两中心的空间距离对于数字产业化影响产业结构优化的调节作用。分别通过构建交乘项、筛选特殊地区样本、以及借用Hotelling竞争模型等方法分析,得出结论:第一,在重庆地区内,存在单独的空间距离调节效应,各区县距离重庆主城区越远,则越无法形成依赖于主城区的经济结构,数字产业化影响产业结构的合理化程度越高;而在四川区域内,同样存在单独的空间距离调节效应,由于成都市的经济规模更大,因而四川区域内各市距离四川成都市越远,产业结构越依赖于成都,故其自身的合理化程度越低。第二,无论是出于中心地带地区数字产业化发展推动当地产业结构合理化还是高级化的角度下,都能得到在双城经济圈的两大中心之间,重庆市区的影响力和辐射效果均强于成都市,对两中心的交界地带产业结构以及数字优化方面存在着更强的空间辐射作用。第三,在双中心影响中心地带的条件下,无论是产业结构的合理化还是产业结构的高级化过程,均反映出了成都重庆双中心对于中心地带全范围内同等影响力的效果。By constructing unbalanced short panel data with a time span from 2015 to 2021,this paper discusses the adjustment effect of the spatial distance between cities(districts and counties)and the two centers on the influence of digital industrialization on the optimization of industrial structure in the Chengdu-Chongqing economic circle.By constructing cross-multiplying terms,screening samples from special regions,and using Hotelling competition model,it draws the following conclusions.Firstly,in Chongqing,there is the separate spatial distance adjustment effect.The farther each district and county is from Chongqing's main urban area,and the more unable it is to form an economic structure dependent on the main urban area,so the higher the rationalization degree of digital industrialization affects the industrial structure.In Sichuan,there is also the separate spatial distance adjustment effect.Because of the larger economic scale of Chengdu,the farther the cities in Sichuan area are from Chengdu,and the more their industrial structure depends on Chengdu,so the lower their rationalization degree.Secondly,whether from the perspective of rationalization or upgrading of local industrial structure promoted by the development of digital industrialization in the central area,it can be concluded that between the two major centers of Chengdu-Chongqing economic circle,the influence and radiation effect of Chongqing are stronger than that of Chengdu.And there is a stronger spatial radiation effect on the industrial structure and digital optimization of the border area of these two centers.Thirdly,under the condition that the dual centers affect the central zone,both the rationalization of industrial structure and the upgrading of industrial structure reflect the effect of the dual centers of Chengdu and Chongqing on the overall scope of the same influence on the central zone.
