中国城市数智化转型对产业现代化的影响

Impact of Urban Digitalization Transformation on Industrial Modernization in China

文章将“宽带中国”试点政策和“智慧城市”试点政策分别作为城市数字化和城市治理智能化转型的外生冲击,基于多时点双重差分模型及空间双重差分模型探究了政策不确定性下数智化转型对中国产业现代化的作用。结果表明:①“宽带中国”试点政策和“智慧城市”试点政策对产业现代化水平均有显著的正向作用,意味着城市数智化转型能够促进产业现代化水平提升。②随着经济政策不确定性及外贸政策不确定性增加,城市数智化转型对产业现代化水平的促进作用增强。③通过构建空间双重差分模型分析,发现城市数智化转型不仅局限于本地区,同时还存在明显的空间溢出效应。结论对于在政策不确定性增加的背景下促进产业升级和推进现代化产业体系建设具有重要的政策启示和借鉴意义。

To analyze the impact of urban digital and intelligent transformation on the level of industrial modernization under policy uncertainty,this study takes the"Broadband China"pilot policy and the"Smart City"pilot policy as exogenous shocks of urban digitalization and intelligent governance transformation respectively.Based on the multiperiod difference-in-differences model and the spatial difference-in-differences model,it explores the effect of digital and intelligent transformation on China's industrial modernization under policy uncertainty.The results are as followings:1)Both the"Broadband China"pilot policy and the"Smart City"pilot policy have a significant positive effect on the level of industrial modernization,indicating that urban digital and intelligent transformation can promote the enhancement of industrial modernization.2)With the increase of economic policy uncertainty and foreign trade policy uncertainty,urban digital and intelligent transformation has a stronger role in promoting the level of industrial modernization.3)Through the analysis of spatial difference-in-differences model,it is found that the urban digital and intelligent transformation is not limited to the local area,but also has a significant spatial spillover effect.The conclusion has important policy enlightenment and reference significance for promoting industrial upgrading and advancing the construction of modern industrial system against the backdrop of increasing policy uncertainty.
