This study investigates the impact of Environmental, Social, and Governance (ESG) performance on the green technological innovation (GTI) of Chinese A-share-listed companies, using data from 2009 to 2022. The findings indicate that strong ESG performance significantly enhances GTI, with this effect being more pronounced in state-owned firms and non-high-tech sectors, demonstrating heterogeneity across firm types. Mechanism analysis reveals that ESG performance facilitates GTI by mitigating financing constraints and boosting R&D investments. Moreover, the study identifies a non-linear relationship, wherein the effect of ESG on GTI varies with firm size and environmental regulation intensity, as confirmed through a threshold model. This study not only deepens the theoretical framework linking corporate ESG performance with GTI but also uncovers the practical mechanisms through which ESG performance drives GTI, providing both practical insights and theoretical foundations for governments to formulate corporate green transition policies.
