Short summary

Using over 1000 chemical transport model simulations in the Beijing–Tianjin–Hebei region, we find that the emissions of primary inorganic PM_2.5 make the largest contribution to PM_2.5 concentrations and thus should be prioritized in PM_2.5 control strategies. Among the precursors, PM_2.5 concentrations are primarily sensitive to the emissions of NH₃, NMVOC+IVOC, and POA, and the sensitivities increase substantially for NH₃ and NH_x with the increase in emission reduction ratio.
