摘要
采用不同暴露-反应关系计算天津市不同终端的健康效益,并利用支付意愿法(WTP)和人力资本法(HC)进行经济效益评价。结果表明当天津市PM_(2.5)浓度达到《环境空气质量标准》(GB 3095-2012)规定的日均浓度限值(35μg/m^3)时,因急性的呼吸系统疾病、心血管疾病及全死因引起的死亡可减少1 246、3 290和3 586例,可获得的经济效益为25.51亿元和3.8亿元,占2014年天津市生产总值(GDP)的0.16%和0.024%。当PM_(2.5)浓度达到标准规定的年均浓度限值(15μg/m^3)时,因慢性的呼吸系统疾病、心血管疾病及全死因引起的死亡可减少673、3 427和3 909例,可获得的经济效益为23.05亿元和3.43亿元,占2014年天津市GDP的0.16%和0.022%。
This paper elaborated on the health-benefit evaluation conducted in Tianjin City, which involved the calculation of the health benefits of different endpoints in Tianjin by the exposure-response relationship, and the economic benefit evaluation by the WTP（willingness to pay） and HC（human capital） methods. The results of the evaluation suggested that on condition that the PM2.5 daily average concentration of Tianjin met the limit of 35 μg/m^3 stipulated in the National Environmental Air Quality Standard（GB 3095-2012） the mortality due to acute respiratory disease, and cardiovascular disease could be respectively cut by 1 246 cases and 3 290 cases, and all-cause mortality by 3 586 cases; the health benefits calculated according to the WTP and HC methods were up to 2.551 billion yuan and 0.38 billion yuan, accounting for 0.16% and 0.024% of the GDP of Tianjin in 2014, respectively. If the PM2.5 annual average concentration could meet the concentration limit of 15 μg/m^3 set by the above national standard, the mortality due to chronic respiratory disease, and cardiovascular disease could be respectively cut by 673 cases and 3 427 cases, and the all-cause mortality by 3 909 cases; the health benefits calculated according to the WTP and HC methods were up to 2.305 billion yuan and 0.343 billion yuan, accounting for 0.16% and 0.022% of the GDP of Tianjin in 2014.
