In this paper, the public's willingness to pay for the long-run air quality improvement is examined based on the internet survey data and the employed multinomial Probit model is estimated in a hierarchical Bayes framework. Our results show that the public's willingness to pay for the long-run increase in air quality to the best level in our survey in 20 years is about 47 RMB per person per month for the next 5 years, and the discount rate of that payment is about 3.8%.%公众改善环境之意愿的最直接体现是支付意愿.在介绍了多项式概率模型及其层次贝叶斯估计方法后,利用问卷数据研究了北京市公众(大学生群体)对于改善长期空气质量的支付意愿.结果显示,为了在20年内北京市空气质量良级天数(API＜100)达到90％以上,公众的支付意愿为未来5年47元/人/月,支付意愿随时间的贴现率大约为3.8％.
