摘要
为鼓励网约车用户选择更加低碳的拼车出行方式,引入碳普惠机制,分析用户在不同低碳激励作用下对于网约拼车出行的行为意愿。首先,基于计划行为理论、技术接受模型和感知风险理论,提出关于网约车用户拼车出行意愿影响因素的假设;然后,正交构建了12种涉及不同碳积分价值和拼车里程的碳普惠情景,并采用SP(Stated Preference)调查收集了网约车用户的社会人口信息、心理潜变量以及在不同假设情景下的拼车出行意愿;最后,基于结构方程模型对网约车用户在碳普惠机制下的拼车出行意愿进行建模分析。研究发现:碳积分价值、拼车里程、态度、主观规范和低碳价值观对拼车出行意愿有显著直接影响;感知有用性、感知风险对拼车出行意愿有显著间接影响;随着碳积分价值的提高,用户的拼车出行意愿增强,且态度及主观规范的作用减弱,而低碳价值观的作用增强。研究结果证明了碳普惠机制可有效促进网约车用户选择拼车出行。
To encourage online ride-hailing users to choose the ridesplitting services that are more low-carbon,a carbon inclusion scheme was introduced for analysis of ridesplitting behavioral intention of online ride-hailing users under different low-carbon incentives.Firstly,hypotheses of the influencing factors on online ride-hailing users′ willingness to ridesplitting were proposed based on the theory of planned behavior,technology acceptance model,and perceived risk theory.Then,12 scenarios of the carbon inclusion scheme with different carbon credit price and ridesplitting distance were constructed orthogonally.Meanwhile,a survey using stated preference(SP) methodology was conducted to collect the socio-demographic information,psychological latent variables,and ridesplitting intentions of online ridehailing users under different hypothetical scenarios.Finally,a structural equation model was employed to model the ridesplitting intentions of online ride-hailing users under the carbon inclusion scheme.The results show that carbon credit price,travel distance,attitude,subjective norms and lowcarbon values have significant direct effects on ridesplitting intention while perceived usefulness and perceived risk have significant indirect effects on ridesplitting intention.Specifically,as the carbon credit price increases,users′ willingness to ridesplitting increases,and the effect of attitudes and subjective norms weakens,while the effect of low-carbon values strengthens.The research findings prove that the carbon inclusion scheme could effectively promote online ride-hailing users to choose ridesplitting.
