Consumers’ decisions to purchase electric vehicles in Bangkok, Thailand

The Thai government is actively promoting the adoption of electric vehicles (EVs) to enhance environmental sustainability and reduce dependence on fossil fuels. This study investigates the factors that influence consumer decisions to purchase EVs in Bangkok, aligning with national efforts to transition from internal combustion engine vehicles. Based on a sample of 400 valid survey responses collected between April and September 2024, logistic regression model identifies key influencing factors, including gender, age (particularly middle-aged adults), marital status, income level (especially middle- and high-income groups), car ownership, travel distance, and the availability of EV charging stations. Specifically, the installation cost of home charging infrastructure does not significantly affect purchasing decisions. The findings highlight the critical role of demographic characteristics, travel behavior, and infrastructure availability in shaping consumer preferences. Targeted policy measures should prioritize the expansion of strategically located charging stations, particularly near workplaces and commuting corridors, to encourage adoption among likely EV purchasers. Additionally, sustained government support through subsidies, financing schemes, and public infrastructure development is essential to promote equitable access. These strategies will contribute to Bangkok’s long-term goal of achieving a more sustainable and inclusive urban mobility system.
