摘　　要：以随机价值理论为基础,通过长沙、石家庄、南京、济南等城市的居民问卷调查,获取大气环境质量改善的支付意愿,并对比不同价值诱导技术下和不同地区支付意愿的差异。结果表明:1)超过20%的受访者表示肯定愿意支付费用,其中石家庄市占比最高,达28.45%;2)开放式诱导技术下,支付意愿的均值和方差较大,考虑受访者偏好的不确定性后,均值和方差减小,使用随机支付卡测度的支付意愿均值的样本平均数高于多边界离散选择式,但方差的样本平均数较小;3)支付意愿的高低受城市环境质量和居民收入水平的共同影响;4)市中心支付意愿均值普遍高于市郊,但占家庭总收入的比例相差不大,尤其对污染严重的城市区域差异将会缩小。研究能够为个人偏好的不确定性测度、不同价值诱导技术的选择等提供经验证据。Based on random value theory,research was carried out through questionnaire survey to residents in Changsha,Shijiazhuang,Nanjing and Jinan,to obtain their willingness to pay(WTP)for air quality improvement.The differences of WTP under various value elicitation techniques and different regions were compared as well.The results show that:More than 20%of the respondents expressed positive attitude towards air protection of the four selected cities,with Shijiazhuang accounting for the highest proportion of 28.45%.The mean and variance value of WTP are larger estimated through Open-end question(OE),while they will decrease after considering the uncertainty of respondents’preferences.The sample average value for the mean of WTP measured by Stochastic Payment Card(SPC)elicitation technique is higher than that measured by Multiple Bounded Discrete Choice(MBDC),but the average value of variance for samples is small.Resident’s WTP is influenced by the condition of air quality as well as their income level.The average WTP in the city center is generally higher than that in the suburbs,but there is little difference in the share of total household income,especially for the areas with serious pollution.This study provides references for exploring the uncertainty measurement of individuals’preferences and the selection of different value elicitation techniques.
