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.

The relevance of the technological competitiveness of the national economy at the present stage of Ukraine's socio-economic development is grounded. The purpose of the article is to justify strategic priorities for the technological competitiveness of the Ukrainian economy. The study uses a scientific method of analysis and synthesis to justify the strategic tasks and strategic priorities of the state policy of technological competitiveness strengthening. The principles of state policy to ensure the technological competitiveness of Ukraine's economy are defined. The purpose of the state policy of ensuring technological competitiveness of the national economy is defined as strengthening of external and internal technological competitiveness through the development of internal competition and strengthening of production competitiveness on the basis of advanced technological innovations and information technologies, systemic support of elements of innovation infrastructure, formation, and realization of intellectual and human resources potential of technological economic development. The paper shows that modern policy of ensuring technological competitiveness of Ukraine's economy is formed in conditions of the modern challenges of global competition, namely the influence of global crises and financial and economic instability; increase of external expansion through globalization processes, development of information economy; pressure of the country's debt obligations; the growth of import dependence; high external labor migration activity; disruption of economic development through military conflict and hybrid attacks; critical disparities of regional development. The strategic priorities of state policy for the technological competitiveness of Ukraine's economy are defined: intensification of technological development of economy, growth of the general level of innovation activity, formation of the competitive intellectual property market, development of infrastructure for support of technological innovations, improvement of the resource provision of innovation activity.
