ABSTRACT

The Fourth Industrial Revolution has significantly transformed the global industrial landscape by integrating digital technologies, automation, artificial intelligence, and smart manufacturing systems into economic activities. This study aims to examine the emerging dimensions of industrial, trade, and innovation policies within the context of Industry 4.0, with particular emphasis on the experiences of Portugal and Brazil. The research investigates the extent to which Industry 4.0 has influenced policy formulation, industrial competitiveness, technological advancement, and international trade performance in both countries. The study further explores the limitations and impacts of industrial modernization strategies, innovation frameworks, and trade policies under rapidly changing technological environments. A descriptive research design was adopted using documentary analysis and secondary data sources collected from governmental reports, policy documents, industrial statistics, and international economic databases. The findings reveal that industrial, trade, and innovation policies in Portugal and Brazil were considerably influenced by economic crises, technological transformation pressures, and global market uncertainties during the period under analysis. The study also identifies structural limitations related to technological diffusion, industrial productivity, innovation capacity, and international trade integration. Moreover, both countries continue to face challenges in expanding their participation in global value chains outside the framework of regional economic integration, trade blocs, and free trade agreements. The study concludes that Industry 4.0 requires comprehensive policy restructuring focused on digital transformation, technological investment, innovation ecosystems, and industrial competitiveness. Strengthening collaborative industrial strategies and improving technological capabilities are essential for Portugal and Brazil to achieve sustainable economic growth and stronger participation in the global digital economy.
