Abstract

A multiphase difference-in-differences model is used to explore the impacts of digital infrastructure investment on carbon emissions based on the Broadband China (BC) policy. The benchmark analysis of pilot cities reveals that the BC policy is associated with carbon emissions reductions of approximately 0.05 %. The mechanistic analysis indicates that the BC strategy increases urban innovation capacity, motivates the public to live environmentally friendly lives, optimizes the industrial structure, and, as a result, reduces carbon emissions in cities. This study offers valuable reference data for resolving the dilemma of promoting emission reduction while maintaining economic growth to achieve the dual-carbon target.
