Air pollution is a major environmental issue in China and imposes severe health burdens on Chinese citizens.

Consequently, China has deployed a series of control measures to mitigate fifine particulate matter (PM2.5).

However, the extent to which these measures have been effective is obscured by the existence of confound

ing meteorological effects. Here, we use a newly developed reduced-form model that can address emission

driven PM2.5 trends and control for meteorological effects to examine the level of PM2.5 reduction across 367

cities since the introduction of the Air Pollution Prevention and Control Action Plan (the Plan) in 2013. Our fifind

ings show that, on average, the national annual mean level of PM2.5 decreased by 34% from 2013 to 2019 after

the removal of meteorological effects, about 10% less than the reduction level offificially observed. Despite

this difference, assuming that current control efforts continue through 2035, the long-term air-quality target

of 35 mg/m³ as determined by the recently updated Plan will be met.
