自2013年以来，中国在空气污染控制方面做出了巨大努力。然而，缺乏对城市一级国家和地方空气污染控制措施的环境、健康和经济共同效益的评估。我们分析了2013年至2017年中国空气污染最严重的城市之一济南的地方空气污染控制政策和实施情况。我们评估了废气排放、空气质量、相关特定疾病的死亡率和发病率以及相关经济效益的变化。我们还预测了PM2.5浓度降至15 μ g/m的未来情景（3）。研究期间，济南市SO2和NOx排放量有明显下降。环境空气污染的年减少率为SO2 72.6%，PM2.5 43.1%，PM10 34.2%。2017年共避免了2，317例（95%CI：1，533 - 2，842）过早死亡和15，822例（95%CI：8，734 - 23，990）相关发病病例，经济效益总计3.177亿美元（95%CI：227.5-458.1）。将PM2.5浓度降至15 μ g/m3将导致与PM2.5相关的非意外死亡率降低70%，与PM2.5相关的发病率降低95%，这相当于12.895亿美元（95%CI：825.8- 1673.6）的经济效益。国家和地方的大气污染治理措施为中国这座曾经污染严重的城市带来了显着的环境、健康和经济效益。
China has made great efforts in air pollution control since 2013. However, there is a lack of evaluation of environmental, health and economic co-benefits associated with the national and local air pollution control measures at a city level. We analyzed local air pollution control policies and implementation in Jinan, one of the most heavily air-polluted cities in China between 2013 and 2017. We assessed the changes in exhaust emissions, air quality, mortality and morbidity of associated specific-diseases, and related economic benefits. We also projected the future scenarios of PM2.5 concentration dropped to 15 mu g/m(3). There were significant decreases in exhaust emissions of SO2 and NOx in Jinan during the study period. Annual reductions in ambient air pollution were 72.6% for SO2, 43.1% for PM2.5, and 34.2% for PM10. A total of 2,317 (95%CI: 1,533-2,842) premature deaths and 15,822 (95%CI: 8,734-23,990) related morbidity cases had been avoided in 2017, leading to a total of US$ 317.7 million (95%CI: 227.5-458.1) in economic benefits. Decreasing PM2.5 concentrations to 15 mu g/m(3) would result in reductions of 70% in total PM2.5-related non-accidental mortality and 95% in total PM2.5-related morbidity, which translates into US$ 1,289.5 million (95%CI: 825.8-1,673.6) in economic benefits. The national and local air pollution control measures have brought significant environmental, health and economic benefits to a previously heavy polluted Chinese city.
