| 摘 要： | 从非集计视角对空气污染环境下居民出行风险感知的影响因素进行研究.从风险发生可能性和风险后果严重性来观测风险感知;以AQI(air quality index)指数、出行者社会经济属性和其对AQI信息关注度作为显变量构造结构方程模型,验证其主效应,进而验证AQI信息的调节效应.实证结果表明:空气污染会显著增加出行者的风险感知;40岁以上中年人群比青年人群对空气污染的风险感知明显减小;AQI信息对出行者风险感知的调节作用显著,尤其是在空气污染较为严重时更明显;与敏感人群同行会促使出行者查询AQI信息,增加出行者的风险感知.

| Abstract: | People have to face the risk of serious air pollution in their daily travel.The influencing factors of residents'' travel risk perception in air pollution environment were studied from the disaggregate perspective.The risk perception was taken as a latent variable,which was described from the two aspects of the subjective probability of risk and the assessment of the severity of consequences.The AQI (air quality index),travelers'' social and demographic characteristics and their attention about AQI were taken as observed variables.Two structural equation models were established to verify the main effect of the above mentioned three observed variables and the moderation effect of AQI information on the travelers'' risk perception.The empirical results show that:air pollution will significantly increase travelers'' risk perception;the risk perception of middle aged travelers above 40 years old is much less than that of young people;the moderation effect of AQI information on travelers'' risk perception is significant,especially when air pollution is very serious;travelers who walk with sensitive people will increase the risk perception due to querying AQI information. |
