Abstract:
This study aims to analyze the factors influencing consumers purchase intention toward sustainable washing machines in Bangkok, focusing on the impact of sustainable washing machines attributes, attitudes, subjective norms, and perceived behavioral control. Data were collected via QR code-based questionnaires from 400 respondents aged 30 and above residing in Bangkok. Descriptive statistics and multiple regression analysis were employed for data analysis.
The results reveal that attitudes, subjective norms, and perceived behavioral control positively influence purchase intention, while overall product attributes of sustainable washing machines do not show significant influence. However, specific attributes such as water-saving capabilities and reduced carbon emissions significantly affect consumers purchase intention. From the study, washing machines manufacturers in Thailand can apply the results to enhance their communication strategies by emphasizing the environmental value of their products, leveraging influencers or reference groups, and designing clear and accessible energy labels. These strategies can help align marketing plans with consumer needs and create competitive advantages in the sustainable washing machines market.
