The rapid economic growth has brought tremendous pressure on the environment and caused severe air pollution in China. This study empirically examines causes of air pollution in China. Panel-corrected standard errors procedure (PCSE) was used to analyze major determinants of increasing or reducing emissions of sulfur dioxide (SO<sub>2</sub>) and nitrogen oxides (NO<sub>X</sub>) in 30 Chinese provinces. The estimation results show that SO<sub>2</sub> emission is mitigated as per capita regional GDP increases, but the relation between emission of NO<sub>X</sub> and per capita regional GDP is found to have an inverse N-shaped curve, which implies that emission of NO<sub>X</sub> is ultimately expected to decline with economic growth. As for increasing factors of air pollutants, electricity consumption is a significant common source of SO<sub>2</sub> and NO<sub>X</sub> emissions. Moreover, the results show that increment of coal consumption significantly affects emission of SO<sub>2</sub> while increase of natural gas consumption reduce emission of SO<sub>2</sub>. On the other side, investment in energy industry, and investment on treatment of waste gases are determinants of mitigating emissions of SO<sub>2</sub>, but have no impact on NO<sub>X</sub>. Consumption of diesel, truck ratio and number of vehicles increase emission of NO<sub>X</sub>. Meanwhile, higher precipitation rate is a common determinant of mitigating emissions of SO<sub>2</sub> and NO<sub>X</sub>. Policy implications are suggested in the conclusion.
