Purpose – This study examines the implementation of green technology policy in East Java Province by analyzing the gap between regulatory commitments and implementation practices, as well as the factors shaping multi-actor collaboration in the adoption of green technology. The study also explores the relevance of a hexahelix-based collaborative governance approach for strengthening policy implementation at the local level. Methodology – This study employed a qualitative research design using in-depth interviews, participatory observation, and document analysis. Data were collected from relevant actors involved in green technology policy implementation and analyzed through data triangulation to ensure the credibility of the findings. Findings/Results – The findings indicate that the implementation of green technology policy in East Java is supported by political commitment and growing awareness among communities and businesses. However, implementation remains constrained by limited resources, institutional fragmentation, inadequate policy incentives, and socio-economic resistance, particularly among micro, small, and medium enterprises (MSMEs). These conditions demonstrate that policy implementation is shaped not only by regulatory and administrative factors but also by the quality of relationships and coordination among actors. Originality/Value – This study extends the conventional policy implementation perspective by incorporating collaborative governance to explain the relational and institutional dimensions of multi-actor implementation. The findings highlight the relevance of a hexahelix-based collaborative governance framework to integrate government, business, academia, communities, media, and other relevant actors in addressing implementation barriers. The study contributes to the development of a more integrated and inclusive approach to green technology policy implementation and provides a framework for strengthening local-level collaboration toward sustainable development.
