The spatial spillover effect of higher SO2 emission tax rates on PM2.5 concentration in China
Kaifeng Wang e outros, 2023 · Scientific Reports
Raising SO2 emission tax rates above the national statutory minimum significantly reduced local atmospheric PM2.5 concentration by 0.024 μg/m3 per unit increase in the real tax rate.

Contexto
What changed: Chinese cities adjusted SO2 discharge fee and environmental tax rates above the legal minimum standard between 2004 and 2019. Comparison: Cities that strictly followed the national statutory minimum tax rate. Limits: Relies on formal tax rates rather than actual collected revenues or enforcement intensity.
