Does the digital economy reduce air pollution? Evidence from 30 Chinese provinces and municipalities

Our study aims to investigate whether and how the development of the digital economy can reduce air pollutant emissions in China. Specifically, using a fixed effect model and an empirical test that exploits pollutant emissions in 30 Chinese provinces from 2011 to 2020, we explore the impact of digital economy development on air pollution through three mechanisms: public attention to environmental pollution, production efficiency, and environmental governance efficiency. Additionally, we provide heterogeneity analysis based on regions, industrial structure, and years of schooling. Findings are crucial for policymakers and environmentalists concerned about economic development's effects on the environment.
