The relevance of the research is driven by the profound structural deformations in the national economy, which have been exacerbated by the full–scale war of the russian federation against Ukraine and have resulted in a significant reduction in the share of the manufacturing sector in GDP. Concurrently, integration into the European Union mandates new requirements for decarbonization, increased resource efficiency, and the adoption of modern management standards. In these circumstances, eco–industrial parks emerge as a crucial instrument that combines the goals of re–industrialization and environmental modernization, thus creating a foundation for improving industrial productivity, innovation, and sustainability. Ukraine became the first country in Europe to adopt a national standard that establishes the regulatory framework for scaling this model and ensuring its adaptation to EU industrial policy.The aim of the research is to identify the potential of eco–industrial parks as a key instrument for the structural transformation of Ukrainian industry in the context of European integration and harmonization with European sustainable development norms.Research methods. The research utilized a systemic–institutional approach, comparative analysis of the dynamics of the manufacturing industry’s share in the GDP of Ukraine and Central and Eastern European countries based on World Bank data, as well as a content analysis of expert analytical materials from DNDIIME, NISD, and Top Lead. The analytical model is grounded in the principles of sustainable development, industrial symbiosis, and the concept of «green» transformation.Research results. It was found that the share of the manufacturing sector in Ukraine’s GDP in 2024 was 8.41%, which significantly trails the figures for Poland (15.40%) and Czechia (20.04%). This gap is institutionally determined and reflects different rates of structural modernization. It is argued that eco–industrial parks can become a basic mechanism for correcting this imbalance through the integration of environmental, technological, and social sustainability criteria. The state policy «Made in Ukraine» is viewed as a hybrid model of state support that combines production incentives, localization in public procurement, export promotion, and the formation of a positive image of Ukrainian manufacturers.Conclusions. Eco–industrial parks are the institutional core of Ukraine’s transition from fragmented approaches to a systematic industrial policy oriented toward EU standards. Their development, combined with state programs for branding national manufacturers and international technical assistance from UNIDO and SECO, forms the basis for convergence with European industrial architecture and sustainable growth in the share of manufacturing in GDP to the level of Central and Eastern European countries.
