Key Points

The study aims to evaluate the credibility of ESG scores through the lens of China’s emissions trading system and its impact on green technological innovation.
Utilized panel data of China's A-share listed firms from 2008 to 2020.
Employed a multi-period difference-in-differences (DID) framework with firm and year fixed effects.
Conducted robustness checks, including event-study diagnostics and placebo tests.
Linked ETS exposure to green technological innovation using a bootstrapped mediation-style decomposition.
ETS exposure significantly enhances firm-level ESG performance.
There is an increase in green technological innovation (GTI) linked to ETS exposure.
The indirect pathway through GTI is notably stronger for firms with tighter financing constraints and concentrated ownership.
