摘 要 目的 通过意愿支付(WTP)调查法,研究基于辽宁省人群偏好的成本-效用阈值(WTP/Q),为相关决策提供依据和参考。
方法 采用问卷调查的方式,以配额抽样和滚雪球抽样相结合的抽样方法,对辽宁省一般人群进行电话访谈,收集调研数据并分
析;使用Probit回归结合广义线性模型对影响WTP/Q的相关因素进行分析。结果 共纳入一般人群755人,辽宁省人群的WTP/Q
为119 175元,对于提高生命质量的WTP/Q平均值为84 902元,而对于延长生存时期的WTP/Q平均值为188 005元。影响因素分
析结果表明,年龄越大,人们购买医疗干预措施的概率越低;受教育程度越高,收入越高,WTP/Q值越大;同时,受访对象的身体感
受如疼痛、抑郁也会影响WTP/Q结果;与改善生命质量的情境相比,延长生存时期情境的WTP/Q更高。结论 基于WTP调查法估
算的辽宁省WTP/Q约为同期辽宁省人均国内生产总值的2.07倍;延长生存时期情境的WTP/Q约是提高生命质量情境的2.21倍,
在相关测算或决策中应对提高生命质量和延长生存时期的干预措施予以区别对待。

ABSTRACT OBJECTIVE To study the cost-utility threshold (WTP/Q) based on the preference of the population in Liaoning
province with willingness-to-pay(WTP) survey method, and to provide reference for decision-making. METHODS Using the
method of questionnaire survey, quota sampling combined with snowball sampling were used to conduct telephone interviews with
the general population in Liaoning province, collect data and analyze it. Probit regression combined with generalized linear model
was used to analyze the relevant factors affecting WTP/Q. RESULTS A total of 755 general people were recruited. The WTP/Q of
Liaoning population was 119 175 yuan,the average WTP/Q for improving the quality of life was 84 902 yuan, and the average
WTP/Q for extending the survival period was 188 005 yuan. The analysis of influential factors showed that the older the age, the
lower the probability of people purchasing medical interventions; the higher the education level and income, the greater the WTP/
Q; at the same time, the physical feelings of the interviewee, such as pain and depression, could also affect the WTP/Q results;
compared with the scenario of improving quality of life, the WTP/Q for the extended survival period was higher. CONCLUSIONS
The WTP/Q of Liaoning province based on the WTP survey method is about 2.07 times of the per capita gross domestic product of
Liaoning province in the same period. The WTP/Q for extending survival period is about 2.21 times that of improving the quality of
life. Therefore, interventions to improve quality of life and to extend the survival period need to be treated differently, in
measurement or decision-making.
