This study uses the data of 280 Chinese prefecture-level cities from 2008 to 2019 as the research samples, and the DID (difference-in-difference) model to explore the negative impact of the Next-Generation Internet Demonstration City Policy (NGIDCP) on urban environmental pollution, and further analyzes the transmission mechanisms of informatization level and technological innovation in this influence. The results show that the NGIDCP can effectively reduce urban environmental pollution, and the conclusion still holds after various robustness tests. The informatization level and technological innovation have some mechanism effects on the impact of the NGIDCP on urban environmental pollution. The results of the regional heterogeneity test show that the negative impact of the NGIDCP on urban environmental pollution is significant in the eastern and western regions and has little effect on the central region. At the end of the paper, some recommendations on urban environmental pollution based on the conclusions drawn from the study are proposed.
