          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.
