Assessing the effectiveness of PM_2.5 pollution control from the perspective of interprovincial transport and PM_2.5 mitigation costs across China.

ABSTRACT: Due to the transboundary nature of air pollutants, a province's efforts to improve air quality can reduce PM_2.5 concentration in the surrounding area. The inter-provincial PM_2.5 pollution transport could bring great challenges to related environmental management work, such as financial fund allocation and subsidy policy formulation. Herein, we examined the transport characteristics of PM_2.5 pollution across provinces in 2013 and 2020 via chemical transport modeling and then monetized inter-provincial contributions of PM_2.5 improvement based on pollutant emission control costs. We found that approximately 60% of the PM_2.5 pollution was from local sources, while the remaining 40% originated from outside provinces. Furthermore, about 1011
