摘要
采用目前美国国家海洋局(NOAA)推荐的双边界二分式条件价值评估方法,对北京市空气质量改善产生的健康效益进行评估.对北京市城八区居民共发放880份调查问卷,调查居民对通过改善空气质量进而使健康免受危害计划的最大支付意愿.结果表明:未来5年内北京市居民每户的平均最大支付意愿为652.33元/a,居民健康总经济效益现值为61.08×10^8~75.41×10^8元;支付意愿影响因素分析表明,支付意愿与居民家庭经济状况、受教育程度、健康状况有正向关系,男性比女性的支付意愿高.分析结果与经济学原理相符,该评估的可靠性得以验证.
The double-bounded dichotomous discrete contingent valuation method recommended by US NOAA was applied to evaluate health gains from air quality improvement in Beijing. Totally 880 questionnaires were randomly sent out to households of Beijing eight districts, and the maximum willingness to pay (WTP) for protecting health from air pollution was elicited. The results show that annual mean WTP in the next 5 years was 652.33 RMB yuan. The total economic health gain from air quality improvement in Beijing ranged from 61.08 × 10^8 RMB yuan to 75.41 ×10^8 RMB yuan (at present value in 2005). The WTP determination factors analysis states that WTP increased with household income, education and health status, and men had larger WTP than women. The results were consistent with economic theory, and thus the validity of the valuation was verified.
