Abstract:
This research aims to study the marketing mix factors influencing the purchasing decisions of Plug-in Hybrid Electric Vehicle (PHEV) among consumers in Chiang Rai province and to examine consumer purchasing behaviour. A quantitative research approach was employed, utilizing a questionnaire to collect data from 400 respondents interested in electric vehicles. The data were analysed using statistical methods, including frequency, percentage, mean, standard deviation, and multiple regression analysis. The results revealed that consumers placed high importance on price, product, and distribution channels, while marketing promotion was the least significant factor of interest. However, price was found to have no statistically significant effect on purchasing decisions. The study indicated that all marketing mix factors, except price, significantly influenced the decision to purchase hybrid electric vehicles.
