Research on the Effect of Urban Innovation Level under Smart City Policy
Based on the panel data of 268 cities in China,this paper studies the impact of smart city pilot policies on urban innovation level through multi-stage difference-difference method,and conducts a series of robustness tests.Finally,the policy effects at different innovation levels are estimated.Baseline regression and robustness test show that smart city construction plays a significant role in promoting the level of urban innovation,and this role is gradually increasing;Quantile regression results show that cities with innovation levels near 0.1 and 0.9 quantiles are less affected by policies,while cities with innovation levels near the median are more affected by policies.
