摘　　要：为了探索用户态度对选择共享自动驾驶汽车(shared autonomous vehicles,SAV)的影响,实施了一项选择偏好调查,获取用户个人特征、对SAV的态度变量及偏好选择;应用多指标多因素模型(multiple indicators and multiple causes model,MIMIC)进行验证性因子分析,进而适配态度变量;引入混合Logit模型构建用户选择SAV的意愿模型,分析偏好选择结果,探索用户特征及态度变量对SAV的影响。结果表明,感知风险(12.75%)和服务质量(9.85%)对SAV的使用意愿影响最大,其余态度变量的影响依次为行为意图、社会影响、感知有用性、感知易用性,弹性值分别为8.17%、7.93%、5.65%、4.46%。因此,未来重点提升SAV的安全性及服务质量是推动SAV发展的重要措施。To examine the effect of attitude on the adoption of shared autonomous vehicles(SAV),a survey was conducted to obtain customers’characteristics,attitude variables and preferences.The multiple indicators and multiple causes model(MIMIC)was applied to implement a confirmatory factor analysis and thus to adapt latent variables.The mixed Logit model was also introduced to construct the preference model of SAV.Then a sensitivity analysis was employed to examine the effect of customers’characteristics and attitude variables on SAV.The results showed that among all the attitude variables,perceived risk(12.75%)and service quality(9.85%)had the greatest impact on the acceptance of SAV,followed by behavioral intention(8.17%),social impact(7.93%),perceived usefulness(5.65%)and perceived ease of use(4.46%).Therefore,we should focus on improving the security and service quality of SAV in the future.
