摘　　要：风险偏好度量方法至今没有"金标准",在研究个体风险决策时存在潜在偏差。本文基于安徽省和河南省两省721份调查数据,运用结构方程模型探索一般风险量表法、特定领域风险量表法以及实验经济学等风险偏好度量方法的有效性。结果显示不同风险度量方法测量的风险偏好值之间存在弱相关,且将实验经济学方法和量表法相结合度量的风险偏好值的数据拟合度最高。被调查者风险偏好整体水平较低,在风险偏好影响因素分析中,年龄、家庭年收入对多种不同度量方法测量下的风险偏好存在显著且稳健的影响,而性别、婚姻状况、受教育程度、家庭总人口、家中是否有18岁以下未成年人、养猪收入占比等影响因素仅对部分度量方法测量下的风险偏好产生显著影响。因此,如不使用实验经济学方法和量表法相结合的度量方法,将可能导致有偏的结论。There is no standard for risk preference measurement,and there is potential deviation in the study of individual risk decision-making.Based on 721 survey data of Anhui Province and Henan Province,this paper uses structural equation model to explore the effectiveness of different risk preference measurement methods.The results show that there is a weak correlation between the risk preference values measured by different risk measurement methods,and the data fitting degree of the risk preference value measured by the combination of experimental and questionnaire method is the highest.The overall level of risk preference of the respondents is low.Gender,marital status,education level,total family population,whether there are minors under the age of 18 in the family and the proportion of pig raising income have significant effects on the risk preference measured by some measurement methods.Therefore,it may lead to biased conclusions if we do not use the measurement method of combination of experimental method and questionnaire method.
