The spatial spillover effect of higher SO₂ emission tax rates on PM_2.5 concentration in China.

ABSTRACT: In this paper, the adoption of SO₂ emission tax rates higher than the legal minimum standard is regarded as a noteworthy policy reform in China (quasi-natural experiment), and a spatial Difference-in-Differences (Spatial-DID) model is constructed to test the direct effects (local effects) and indirect effects (spatial spillover effects) of SO₂ emission tax policy reform on PM_2.5 concentrations in the atmosphere of 285 China's cities. The estimation and calculation results of the Spatial-DID model show that the SO₂ emission tax policy reform can significantly reduce local PM_2.5 concentration and significantly promote PM_2.5 concentration in surrounding areas. The results of heterogeneity analysis show that the SO₂ e
