The Evolving Role of State Aid within the Single Market: Stimulating the European Economic Ecosystem

This paper examines the evolving role of State Aid within the European Union’s Single Market, with a focus on the expansion of the Important Projects of Common European Interest (IPCEI) instrument. While State Aid is generally restricted due to its potential to distort competition, recent economic and geopolitical pressures have prompted a more flexible approach across the EU. The analysis examines how successive crises, from COVID 19 to supply chain disruption and the green and digital transitions, have reshaped EU industrial policy and intensified the use of IPCEIs alongside other instruments, to address market failures and support breakthrough innovation. Using EU State Aid expenditure data, the paper highlights widening divergences in State Aid between larger and smaller Member States and assesses the implications for competitiveness and the cohesion of the level playing field. The study evaluates Ireland’s limited engagement with IPCEIs to date, the fiscal constraints shaping participation of smaller countries, and recent policy commitments aimed at increasing involvement. It argues that while IPCEIs present significant opportunities for technological innovation, they also carry risks of market fragmentation and an emerging subsidy race. The paper concludes by outlining policy options to strengthen Ireland’s strategic positioning within an evolving EU State Aid landscape.
