Anchored in Dynamic Capabilities Theory, the research explores how externally oriented marketing efforts foster internal innovation and long-term sustainability in heritage-based enterprises.

The data were analyzed using Structural Equation Modeling with the partial least squares (SEM-PLS) technique. The results reveal that green marketing enhances sustainability, both directly and indirectly, by stimulating innovation with in resource-constrained traditional businesses. These findings underscore the dual role of eco-marketing as both a communication strategy and driver of adaptive capability.

The study contributes to theoretical development by contextualizing capability-building in culturally embedded enterprises and emphasizing alignment between ecological practices and heritage values. It illustrates how sustainability-oriented marketing enhances stakeholder engagement and fosters innovation that improves market relevance and organizational resilience. Practically, this research offers insights for artisans, business leaders, and policymakers on embedding environmental values into heritage branding and production.
