This study applies qualitative content analysis of the regulations text using frameworks fromtheorists’ view of central points of self-sufficiency.The findings reveal that the regulation combines both offensive realism inthe context of strengthening and enhancing the EU’s domestic research and innovation regarding semiconductors for global competitiveness, and defensive realism by attracting semiconductor companies with benefits tosecure self-sufficiency and European supply chains. Further research is needed to explore the long-term impact of EU’s regulation and how effective and useful the approach is to the European semiconductor sector.
