      偏差影响因素偏差描述偏差处理
      投标起点偏差CVM研究中建议的投标起点和间距使受访者产生对WTP范围的误解预调查确定基本支付范围,采用支付卡格式,增加“其他金额”选项
      抗议反应偏差受访者倾向于反对假想市场和支付工具而引起的偏差支付方式置于是否同意支付问题之前,增加抗议支付原因调查
      假象偏差受访者对假想市场问题与面对真实市场时反应不同而导致与真实结果的偏差强调受访者考量家庭经济约束
      策略性偏差受访者试图影响调查结果或实际决策而故意隐瞒真实支付意愿强调匿名调查和调查学术用途,剔除异常支付意愿值
      信息偏差对评估对象不够了解导致受访者难以表达支付意愿充分描述评估对象的真实情况,先行设计让受访者进入评估语境的其他问题
      调查者偏差不同调查员和调查语言对评估结果产生的影响统一培训农业局人员来组织调查
