Abstract

There is a growing challenge posed by the coexistence of fine particulate matter (PM2.5) and ground-level ozone (O3). Despite the significant reductions in primary particles and a variety of gaseous pollutants achieved by conventional air pollution control, O3 pollution has remained or even increased in many areas, demonstrating the shortcomings of single-pollutant regulation. This review examines how the efficiency evaluation and path optimization of regional atmospheric governance can be viewed through the prism of synergistic emission reduction to coordinate control of PM2.5 and O3. It initially explains the chemical linkage between PM2.5 and O3 through common precursors, the atmosphere’s capacity for oxidation, photolysis, heterogeneous reactions, and regional transport. It subsequently discusses efficiency evaluation methods, such as indicator systems, data envelopment analysis, slack-based measure models, Malmquist indices, spatial econometric methods, and integrated benefit assessment. The review also discusses pathways for emission reduction across the industrial, power, transport, residential, and agricultural sectors, with a focus on differentiated VOCs-NOx sensitivity, NH3 regulation, structural adjustment, clean-energy transition, process optimization, and scenario-based cost-benefit analysis. Lastly, it suggests a regional path-optimization framework that combines air-quality modeling, economic analysis, cross-regional responsibility sharing, policy synergy, and adaptive, data-driven governance. The review claims that successful atmospheric governance needs to shift toward mechanism-based, regionally coordinated, and welfare-oriented decision-making to achieve sustainable air-quality improvements, health protection, carbon co-benefits, and regional equity.
