| Abstract | China has placed an unprecedented emphasis on developing its ecological civilization since 2014. This
paper examines the evolution of air quality ever since, explains the impacts of major events on air quality,
delves with the DID and RD methods into the causal effects of the CEPI effort and the anti-epidemic
lockdown on air quality based on the city-level daily air quality data, and come up with the observations:
that, from 2014 to 2020, China’s air quality index (AQI) dropped by 20%. CEPI cut average urban AQI by
2.6%–3.4% while pandemic lockdown caused a short-term reduction of 5.2%–12%.
