The impact mechanism of Eco-labels on consumer purchase intention in international trade: A cross-cultural psychological perspective

In response to escalating global environmental challenges and the growing prominence of eco-labeling as a market-based sustainability instrument, this research examines the psychology of culture to analyze the dynamics of eco-labels in international trade and their effects on consumer purchase intentions. Drawing on the Theory of Planned Behavior and Hofstede's cultural dimensions framework, we investigate how purchase decisions vary across cultures regarding eco-label attributes. Using structural equation modeling with data from 1,824 consumers across six culturally diverse countries (United States, Germany, Japan, South Korea, Brazil, and Netherlands), selected through stratified random sampling to maximize cultural diversity representation, we found significant cross-cultural differences in eco-label effectiveness mediated by environmental concern, perceived consumer effectiveness, and green trust. Collectivistic consumers responded more positively to eco-labels emphasizing community benefits, while individualistic consumers preferred personal benefit framing. Uncertainty avoidance moderated the relationship between eco-label credibility and consumer trust in third-party certifications, while long-term orientation influenced the effectiveness of comprehensibility cues. These findings advance sustainable marketing theory and provide actionable strategies for international marketers by demonstrating the importance of culturally-contextualized eco-labeling approaches. For policymakers and eco-label governance bodies, this research offers empirical evidence for developing culturally-sensitive certification frameworks that accommodate diverse consumer information processing styles while maintaining universal credibility standards. The cultural contingency framework developed provides foundations for optimizing eco-labeling policies across international markets, ultimately contributing to more effective sustainable consumption promotion across diverse cultural contexts.
