Understanding the Interconnection of Sustainable Marketing and Local Wisdom in Driving Sustainable Consumer Behavior

Abstract

Grounded in the Theory of Planned Behavior, this study explores how sustainable marketing shapes consumer attitudes, brand image, and brand trust, and their implications for sustainable purchasing behavior among micro, small, and medium enterprises (MSMEs) in Bali. This study also examines the role of local wisdom as a moderating variable in the relationship between sustainable marketing and these three constructs. Using a quantitative approach with SEM-PLS analysis, this study involved 288 respondents who were local consumers of sustainable MSME products. Empirical data were collected through a Google Form-based questionnaire and analyzed using SmartPLS4. The results show that sustainable marketing has a significant effect on attitude, brand image, and brand trust. These three variables are proven to be strong drivers in increasing purchasing decisions for sustainable products. Furthermore, local wisdom does not moderate the relationship between sustainable marketing and attitude, but negatively moderates its relationships with brand image and brand trust, suggesting that culturally rooted consumers apply more critical evaluations to sustainable marketing efforts. These findings highlight the importance of integrating local wisdom authentically into sustainable marketing to strengthen consumer attitudes, brand image, and brand trust. The study contributes to sustainable marketing and consumer behavior theory and provides practical guidance for MSMEs in implementing sustainability strategies aligned with local wisdom.
