Factors Influencing the Decision to Purchase Electric Vehicles in Bangkok and Metropolitan Area

Abstract

This research article aims to: (1) examine the influence of government policy factors on the decision to purchase electric vehicles (EVs); (2) investigate the influence of perceived benefits on EV purchase decisions; and (3) analyze the influence of infrastructure factors on EV purchase decisions in Bangkok and its metropolitan area. This study employed a quantitative research approach. The sample consisted of 385 consumers residing in Bangkok and its surrounding metropolitan areas. A questionnaire was used as the data collection instrument. Data were analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation, as well as inferential statistics through multiple regression analysis, with the level of statistical significance set at 0.05. The findings revealed that the majority of respondents were female, aged 31–40 years, held a bachelor’s degree, worked as government officials or state enterprise employees, and had an average monthly income of 30,001–40,000 baht. Government policy factors significantly influenced EV purchase decisions, particularly measures such as fee reductions, subsidies, and tax incentives. Perceived benefits were rated at the highest level and had a positive effect on purchase decisions. Infrastructure factors were rated at a high level, especially the availability of charging stations and the stability of the electricity supply system. The hypothesis testing results confirmed that government policies, perceived benefits, and infrastructure significantly influenced electric vehicle purchase decisions at a statistically significant level.
