Purpose. The purpose of the study is to assess the impact of intersectoral integration and digitalization on the economic performance of service economy sectors in the European Union and to identify intersectoral differences in the combination of integration, digital, and performance characteristics. Methodology. The methodological framework is based on the theory of intersectoral linkages, concepts of digital transformation, and systemic and ecosystem approaches. Statistical, structural, and comparative analyses were applied. The empirical database was compiled using Eurostat and OECD data for NACE Rev. 2 sectors H, I, J, M, and N across EU countries. Results. The study reveals substantial sectoral differentiation in development dynamics, the nature of intersectoral linkages, the level of digitalization, and economic performance. The highest labour productivity was recorded in the information and communication sector, while professional, scientific and technical activities generated the largest volume of value added; the lowest labour productivity was observed in accommodation and food service activities. Transport and storage were found to exhibit pronounced two-way linkages, whereas accommodation and food services are characterized predominantly by backward linkages. Information and communication, professional, and administrative and support service activities act as important suppliers of resources and services to other economic activities. It is demonstrated that technological digitalization is more strongly associated with productivity than the digitalization of sales channels, while the performance effects of intersectoral integration depend not only on the intensity of linkages but also on their functional orientation. Scientific novelty. The scientific novelty lies in the integrated comparison of the direction of intersectoral linkages, the level of technological and market digitalization, and the performance indicators of EU service economy sectors. Practical value. The practical value of the results lies in their potential use for identifying sectors with insufficient digital maturity and a limited capacity to translate intersectoral linkages into productivity and value-added growth.

Purpose. The purpose of the article is to provide a theoretical substantiation of the role of corporate development in enhancing the economic resilience of agricultural sector enterprises and to conduct a practical analysis of integration mechanisms that strengthen their competitiveness and economic security.
Methodology. The methodological basis of the study is a comprehensive approach combining the provisions of institutional economic theory, systems analysis, and functional analysis. The research employs monographic and statistical methods to generalize scientific findings and empirical observations, as well as comparative analysis and synthesis to identify the key determinants of economic resilience and competitiveness of agricultural enterprises within corporate structures.
Findings. The study demonstrates that corporate development is a key institutional and economic mechanism that contributes to capital concentration, optimization of production processes, and strengthening of the strategic potential of agricultural enterprises. It is substantiated that the formation of corporate structures, such as agroholdings, integrated associations, clusters, and cooperatives, creates a synergistic effect, improving resource efficiency, financial stability, and adaptability to external environmental changes. Integration processes, including mergers, acquisitions, strategic alliances, and cooperation, enhance the resilience of enterprises to market volatility, logistical disruptions, geopolitical risks, and wartime challenges. Vertical integration ensures continuity of production and supply chains, while horizontal cooperation strengthens the positions of small and medium-sized producers. The research also confirms the existence of a mutually reinforcing relationship between corporate development, economic security, and competitiveness, particularly in the context of strategic transformation, digitalization, and integration into global markets.
Originality. The scientific novelty of the study lies in substantiating the interdependence between corporate development, economic security, and competitiveness of agricultural enterprises, as well as in highlighting the role of corporate integration mechanisms as a factor of resilience under conditions of global instability and wartime challenges.
Practical value. The practical significance of the results lies in their applicability for developing corporate strategies of agricultural enterprises, improving state regulation and support mechanisms for integrated agribusiness structures, and strengthening economic security management systems. The findings may also be used by policymakers in designing strategies for post-war recovery and modernization of Ukraine’s agricultural sector.
