Polluting industries: Does green industrial policy encourage green innovation? Chinese perspective evidence

This study investigates the efficacy of green industrial policies in stimulating green innovation within China's polluting industries, over the period 2011-2022. Focusing on 30 provinces, we assess the dynamic relationship between green industrial policy implementation and innovation in environmentally detrimental sectors. Employing Difference-in-Differences (DID) and Propensity Score Matching DID (PSM-DID) models, we analyze comprehensive provincial-level data to quantify the impact of policy measures on green technological advancements. The results reveal a significant positive correlation between green industrial policies and the rate of green innovation, particularly in regions with higher pollution levels. These findings suggest that well-structured green industrial policies can serve as effective catalysts for fostering sustainable technological innovations in polluting industries. Policy implications highlight the necessity of targeted, region-specific approaches to maximize the potential of green industrial policies in promoting environmental sustainability and economic growth.
