不同感知群体对自动驾驶汽车购买和使用意向的研究

Intentions to purchase and use autonomous vehicles for different perceived groups

为探讨L4级自动驾驶汽车(AV)的出行体验对受访者购买和使用意向的影响,受访者被分为体验感知较高和较低群体,在体验前和体验后,利用多项Logit模型建立不同体验感知群体AV购买和使用意向模型。研究结果显示,购买和使用AV的想法不确定程度对体验前、后的选择均产生显著影响,对于体验感知较高群体,体验后该变量的影响程度有所下降,而对于体验感知较低群体则有所增加。AV的价格与购买和使用意向之间呈现较强的正相关关系,价格的升高会增加购买和使用想法的不确定性,从而导致受访者放弃购买AV,选择使用社会共享自动驾驶汽车(SAV)。对于体验感知较高群体来说,体验后对AV行驶过程的感知提升会促进其购买并自己使用AV,而通过提高对AV出行感受和出行安全的感知,将促进他们购买AV并有偿共享给他人使用。另外影响体验感知较低群体对AV购买和使用意向的显著因素数量则明显减少。

In order to investigate the respondents’purchase and use intention of autonomous vehicle(AV)under the L4 AV travel experience,this paper classified the respondents into higher and lower experience perceived groups,and utilized multinomial logit model to establish the pre-and post-experience purchase and use intention model of AV for different perceived group.The results indicate that the degree of uncertainty about the thoughts to purchase and use of AV has a significant effect on the choices of intentions both pre-and post-experience,with the significance of this variable decreasing after the experience for the higher perceived group and increasing in significance for the lower perceived group.There is a strong positive correlation between the price of the AV and thoughts of purchase and usage,with higher prices increasing the degree of uncertainty about thoughts of purchase and usage,the more likely respondents are to shift from purchasing an AV to using socially shared autonomous vehicle(SAV).For the higher perceived group,the higher the perception of the driving process of the AV after the experience,the more they will choose to purchase an AV and use it by themselves,and the improvement of the perception of the travel experience and travel safety will promote them to purchase the vehicle and share it with others for compensation.Whereas,there is a significant decrease in the number of factors influencing the purchase and use intentions of AV for the lower perceived groups.
