    In 2013, China issued “Air Pollution Prevention and Control Action Plan (Action Plan)” to improve air quality. To assess the benefits of this program in Beijing–Tianjin–Hebei (BTH) region, where the density of population and emissions vary greatly, we simulated the air quality benefit based on BenMAP to satisfy the Action Plan. We estimate PM2.5 concentration using Voronoi spatial interpolation method on a grid with a spatial resolution of 1 km × 1 km. Combined with the exposure–response function between PM2.5 concentration and health endpoints, health effects of PM2.5 exposure are analyzed. The economic loss is assessed by using the willingness to pay (WTP) method and human capital (HC) method. When the PM2.5 concentration falls by 25% in BTH and reached 60 μg/m3 in Beijing, the avoiding deaths will be in the range of 3175 to 14,051 based on different functions each year. Of the estimated mortality attributable to all causes, 3117 annual deaths were due to lung cancer, 1924–6318 annual deaths were due to cardiovascular, and 343–1697 annual deaths were due to respiratory. The avoided cases of cardiovascular mortality had the estimated monetary values ranged from 673 to 13,325 million CNY based on WTP method and from 161 to 529 million CNY based on HC method. The avoided cases of respiratory mortality had the estimated monetary values ranged from 120 to 3579 million CNY based on WTP and from 29 to 143 million CNY based on HC. The avoided cases of lung cancer mortality had the estimated monetary values ranged from 1091 to 6574 million CNY based on WTP and the estimated monetary value of 261 million CNY based on HC.
