The European Union's economic output is heavily concentrated in a handful of member states. As of 2025, Germany, France, Italy and Spain together generate 61% of the bloc's GDP, according to Eurostat. But that dominance is slowly eroding: the 'Big Four' accounted for 67.9% in 2005 and 65.3% in 2015.
Germany remains the undisputed heavyweight, contributing 24.1% of EU GDP in 2025 – roughly €4.5 trillion out of a total of €18.8 trillion. France follows with 15.9%, Italy with 12%, and Spain with 9%. The Netherlands completes the top five at 6.2%.
Who is gaining ground?
Poland has been the standout performer over the past two decades. Its share of EU GDP climbed from 2.6% in 2005 to 4.9% in 2025 – a gain of 2.3 percentage points. That is the largest increase of any member state, and it reflects the country's sustained economic growth since joining the EU in 2004.
Ireland and Romania also posted notable gains, with increases of 1.4 and 1.2 percentage points respectively. Smaller economies like Czechia (from 1.2% to 1.8%) and Bulgaria (from 0.3% to 0.6%) have also seen their shares rise, albeit from low bases.
Who is falling behind?
Italy and France have experienced the sharpest declines. Italy's share dropped from 15.6% in 2005 to 12% in 2025 – a fall of 3.6 percentage points. France saw its share shrink from 18.4% to 15.9%, a decline of 2.5 points. Spain and Greece each lost 0.7 points, though for Greece that represented a more significant relative drop, from 2% to 1.3%.
Germany's share has remained remarkably stable, falling just 0.1 points over the 20-year period. However, over the last decade alone, Germany's share has slipped by 1 point, from 25.1% to 24.1%.
The shifting shares reflect broader economic trends. Poland's rise is tied to its integration into European supply chains and strong productivity gains. Italy's decline mirrors its long-standing structural challenges, including low growth and high public debt. France's relative slippage is more gradual but still notable.
It is worth remembering that GDP shares measure the size of an economy, not the wealth of its citizens. For that, economists look at GDP per capita in purchasing power standards (PPS), which adjusts for differences in price levels across countries. A country with a small GDP share, like Luxembourg, can have one of the highest GDP per capita figures in the EU.
As the EU's economic centre of gravity shifts eastward, the bloc's internal balance is changing. Poland's rise is a reminder that EU membership can be a powerful engine for convergence, while the struggles of southern and western economies highlight the uneven nature of European integration.
