 This research examines the effects of digital transformation on the total factor productivity, TFP, of heavily polluting companies. The results show that digital transformation can increase TFP through increased green technology innovation and improved corporate social responsibility. Additionally, it reduces cost stickiness, allowing companies to better manage their costs. Furthermore, the study finds that digital transformation has a greater effect on TFP when applied to heavily polluting companies with high levels of environmental investment, large enterprises, those in non-manufacturing industries, and those owned by the government.
