The Influence of Digital Infrastructure on Carbon Emission Intensity: Evidence from the Broadband China Policy
With accelerating global warming, reducing carbon emissions has emerged as a core task of global climate governance. In this process, digital infrastructure acts as a crucial catalyst for achieving sustainability goals. Drawing on a panel dataset covering 287 Chinese prefecture-level cities between 2010 and 2023, this paper examines how Broadband China policy influences carbon dioxide (CO2) emission intensity via a difference-in-differences approach. The outcomes show that Broadband China policy significantly reduc …
