摘要
本文运用权变评价法(CVM)调查了北京市居民对大气细颗粒物(PM2.5)健康风险的认知状况、行为选择及降低健康风险的支付意愿。结果表明:182.5%的居民认为北京市空气污染较为严重,52.4%的居民知道雾霾天气是由PM2.5引起的并认为其会对自己和家人的健康带来影响,92%的居民认为政府应该承担更多降低PM2.5健康风险的责任。2在降低风险的行为中,能够节省生活成本、有益于身心健康的生活方式和符合日常生活习惯的行为得到了最积极的响应,而会降低居民生活舒适性和增加生活成本的行为支持率相对较低。3在降低30%的PM2.5浓度情景下,居民的支付意愿平均为22.78元/月;在降低60%的PM2.5浓度情景下,居民的支付意愿平均为39.82元/月。而且,居民的个体特征、经济条件、居住位置、交通方式、认知水平及风险沟通等因素,都对降低PM2.5健康风险的支付意愿产生显著影响。
