Abstract: In recent years， the rapid economic and social development of many cities in China has led to the problem of haze pollution. The topic of haze pollution frequently appears in everyone's vision. This paper studies the fundamental ways to prevent and control haze in China， i.e. controlling the production of haze pollutants from the source， by analyzing the mechanism of the control of pollutant sources. The results show that the combustion source and industrial source control in lag periods 1， 2， and 3 is the Granger cause of haze pollution. The traffic source control is not the Granger cause of haze pollution. At the same time， the impulse response model shows that control of combustion source， industrial source and traffic source for China's haze pollution has played an inhibitory role， and thus provides a scientific basis for China to make clear the focus of haze prevention and work out control measures from the perspective of controlling the “three sources”.

Key words: PM2.5, the control of pollutant source, combustion source, industrial source, traffic source, haze pollution
