Abstract: Automated driving vehicles, as a critical domain in the technological revolution following the internet and smartphones, are helpful for industrialization in fostering and developing new quality productivity. And the role of public acceptance in this context is crucial. This study innovatively introduces "perceived risk, media influence, personal innovativeness, vehicle service level, service threshold, and social value" into an extended technology acceptance model to construct a theoretical model of public acceptance of automated driving vehicles. Leveraging first-hand data from 1178 social experiment survey questionnaires, the study employs a structural equation model to empirically explore the influencing mechanisms of the Chinese public's adoption of automated driving vehicles. The research results indicate that personal innovativeness, usage intention, and perceived risk directly influence the public's behavior in using automated driving vehicles, with the former two being positive influences and the latter a negative influence. Meanwhile, personal innovativeness and perceived risk also have indirect positive and negative effects, respectively, on the public's usage behavior. Perceived ease of use and perceived usefulness positively influence the public's intention to use autonomous driving vehicles, thus indirectly affecting their usage behavior positively. Service threshold, vehicle service level, and social value have indirect positive effects on the public's usage behavior through the mediating roles of perceived usefulness, perceived ease of use, and usage intention. Media influence positively affects perceived usefulness and negatively affects perceived risk, indirectly influencing the public's intention and behavior in using autonomous driving vehicles positively.

摘要： 作为继互联网和智能手机之后的又一次技术革命的关键领域，加速实现自动驾驶汽车产业化有助于中国培育和发展新质生产力，其中公众接受度的作用不容忽视。创新性将“感知风险、传播媒介影响、个人创新性、车辆服务水平、使用门槛、社会价值”引入扩展的技术接受模型以构建自动驾驶汽车公众接受度理论模型，并借助1178份一手社会实验调查问卷数据，采用结构方程模型实证探究了中国公众对自动驾驶汽车采纳的影响机理。研究结果表明：个人创新性、使用意图和感知风险对公众自动驾驶汽车使用行为存在直接影响，并且前二者为正向影响，后者为负向影响；同时，个人创新性和感知风险还分别对公众使用行为存在间接正向影响和间接负向影响；感知易用性和感知有用性通过正向影响公众使用意图，进而间接正向影响公众使用行为；使用门槛、车辆服务水平和社会价值通过感知有用性、感知易用性和使用意图三者的中介作用，对公众使用行为产生间接正向影响；传播媒介影响通过正向影响感知有用性和负向影响感知风险，对公众使用意图和使用行为产生间接正向影响。
