Determinants of Intention to Use Ride-Hailing Services in Vietnam: An Integrated Model of Perceived Value and Trust Transfer Theory

Technology Acceptance Model

According to Davis et al. (1989), who explored the technological adoption model, behavioral intention directly influences user behavior. Perceived usability and perceived ease of use are the two critical components of TAM. While perceived ease of use is defined as “the degree to which a person believes that using a particular system would be free from effort,” perceived usefulness is defined as “the degree to which a person believes that using a particular system would enhance his or her job performance” (Davis, 1989). According to TAM, people tend to adopt technologies depending on how well they function and how difficult or simple it is to use them.
