A study on Chinese users’ acceptance of camera monitor system based on the modified UTAUT2 model

With the continuous development of automotive technology, the camera-monitor system (CMS) has gradually emerged as a new type of indirect vision device. However, even after more than 20 years of development, the market penetration rate of CMS in China is still less than 1%. This study aims to explore the key factors influencing the acceptance of CMS among Chinese passenger car users using the modified Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model to break the barriers to acceptance and use. The study collected 394 valid samples through a questionnaire survey and analyzed the data using the structural equation model (SEM). The results show that effort expectancy (EE), performance expectancy (PE), hedonic motivation (HM), and price value (PV) significantly affect behavioral intention (BI), among which EE has the most significant influence, followed by PE, PV, and HM. BI significantly influences drivers’ usage behavior (UB). In addition, facilitating conditions (FC) and habit (HB) have a direct positive effect on UB. This study provides valuable insights for manufacturers to improve product design, optimize user experience, and formulate effective market strategies, helping to accelerate the popularization of CMS in China. At the same time, the research not only expands the application of the UTAUT2 model in the field of automotive technology acceptance but also provides practical significance for promoting the widespread acceptance of CMS.
