Abstract: In order to study the influence mechanism of latent variables on travelers choice behavior intention, taxi and online car-hailing were taken as examples. Convenience, safety, reliability, comfort and economy were selected as exogenous latent variables, while perceived value and behavioral intention were endogenous latent variables. A willingness questionnaire of trip mode choice was designed and surveyed through web, and a structural equation model (SEM) was established. The relationship between travelers travel mode selecting behavior and various latent variables was studied. The results show that the perceived value has a significant positive effect on travelers behavioral intention, and economy and comfort are important factors that affect the perceived value. Travelers pay more attention to the convenience when choosing taxis and pay more attention to safety when choosing online car-hailing.

摘要： 为研究潜变量对出行者选择行为意向的影响机理，以出租车和网约快车为例，选择方便性、安全性、可靠性、舒适性、经济性为外生潜变量，知觉价值、行为意向为内生潜变量，设计了出行者出行方式选择行为调查问卷，进行网上调查；建立了结构方程模型（SEM），研究了出行者出行方式选择行为与各潜变量之间的关系。结果表明：知觉价值对出行者出行方式选择行为意向有显著正影响，经济性和舒适性是影响知觉价值的重要因素；出行者在选择出租车出行时，更加注重方便性，在选择网约快车出行时，更加注重安全性。
