摘　　要：目的评估广西壮族自治区伤寒流行地区居民对Vi多糖疫苗的支付意愿，为开展疫苗推广活动提供依据。方法应用条件价值法（Contingent Valuation Method，CVM）评估居民对伤寒Vi多糖疫苗的支付阈值，使用Prob-it模型进行“价格-接受率”曲线拟合。结果广西壮族自治区伤寒流行地区居民对Vi多糖疫苗的“价格-接受率”模型为：p=Probit^-1（0．88952—0．46296X），平均支付意愿为10．41元，95％可信区间为6．67～16．24元。结论在广西壮族自治区伤寒流行地区，Vi多糖疫苗定价应在10元左右，CVM可较好评估居民对疫苗的支付意愿。Objective To assess willingness to pay （wtp） for typhoid vi vaccine in typhoid epi- demic area in Guangxi Zhuang Autonomous Region and to provide evidence for introduction of the vaccine. Methods Applying the method of wtp was investigated in typhoid epidemic area,the curve of ＂price-accept ratio model＂was drawn up with Probit regression. Results The formula of ＂price-accept ratio model＂ was described as following. Probit （p） = 0. 88952- 0. 46296X. The WTP for typhoid vi vaccine was ￥10. 41, with a 95% confidence interval of ￥6.67～ 16.24. Conclusions WTP for typhoid vi vaccine was around ￥10 in Guangxi typhoid epidemic area. The Contingent Valuation Method was applicable in the investigation of WTP.
