Consumer Purchase Intention For Hybrid Electric Vehicles (HEVS) In Ho Chi Minh City, Vietnam

Abstract

Relying on energy-intense transportation systems could escalate the chances of environmental degradation. A shift of transportation modes from a gasoline-powered internal combustion engine (ICE) vehicle to decarbonizing the transportation system is a viable method of mitigating carbon emissions. However, the adoption rate of environment-friendly cars is still low globally (especially in Vietnam) and vital to explore. Firstly, this study examines the factors influencing individuals' intention to purchase hybrid vehicles by developing a research framework based on the Theory of Planned Behavior, integrated with economic values and performance factors as additional variables. Secondly, data were collected from 261 car users across Vietnam's metropolitan city, Ho Chi Minh City. Lastly, the findings augment the rich theoretical basis of the Theory of Planned Behavior by incorporating economic values and performance factors as auxiliary variables assessing individuals' behavior in the sustainable transportation domain, which constitutes the novelty value of this study. The outcomes imply the need for the automotive industry in Vietnam and car dealers to understand the consumers' preferences on time and take fast actions to reflect on the trends of using hybrid cars for energy-saving and environmental protection. Alternatively, the findings could guide the government and suppliers to take countermeasures for adopting hybrid cars in Vietnam. Overall, this study infers that adopting hybrid vehicles as an alternative for improving transport energy efficiency and reducing dependence on energy-intensive transport. It can only succeed if people are given enough information and education, fostering trust, empowerment, and confidence in their ability to drive hybrid electric vehicl
