A total of 10,184 cases, receiving fines totalling 8.7 million yuan, were due to pollution from mobile emission sources.
Among these, more than 10,000 vehicles were punished for excessive exhaust emissions.
Fines totalling 142 million yuan, involving 2,943 cases, were issued for fixed pollution emission sources.
Nearly half of these violations were reported for air pollution, state-run Xinhua news agency reported.
Beijing authorities carried out a series of measures to tackle air pollution in 2016, such as cutting coal consumption, ordering construction sites to reduce dust, and removing high-polluting vehicles from roads, it said.
Beijing has a four-tier alert system for pollution, with red the highest, followed by orange, yellow and blue.
Also, more than 5,600 environmental protection violation cases were filed in two Chinese provinces last year.
Fines totalling 420 million yuan (USD 60.6 million), involving 4,242 cases, were issued from January to November last year in the central province of Henan.
A total of 2,062 people and 2,505 companies were punished for dereliction of duty, illegal discharge of pollutants and faking data during the same period.
About 3,300 companies had been investigated and 1,853 people detained, flagged for investigation or charged for misconduct linked with pollution, the report said.
Henan and Hebei, home to a large number of power plants, as well as coal and steel companies, are among the regions worse hit by smog in China.
To tackle air pollution, the two have vowed to cut capacity and eliminate outdated facilities.
In the first 11 months of 2016, Henan removed over 430,000 high-polluting vehicles from its roads and ordered 12,300 construction sites to reduce dust, a major source of smog.
It has pledged to cut another 32 million tonnes of iron and steel capacity this year.
The average PM 2.5 density dropped 9.1 per cent in 2016 in Hebei and 10.7 per cent in the first 11 months of 2016 in Henan, the report said.
