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 multi-period 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.
