"Enlargement has served as an anchor of stability and a driver of democracy and the rule of law in Europe," EU Enlargement Commissioner Olli Rehn said in a statement.
In the report published last Friday, the Commission said enlargement had brought about huge economic and political benefits for both sides. "Economically, enlargement has led to increased living standards in the new member states, while creating export and investment opportunities for the old ones," the report said.
The report said that income per capita in new member states rose from 40 percent of the old member states' average in 1999 to 52 percent in 2008, while economic growth averaged 5.5 percent per year in 2004-2008 compared to 3.5 percent in 1999-2003.
Such progress did not come at the expense of the old countries, which averaged growth of around 2.2 percent annually in 2004-2008, with a similar figure for 1999-2003.
Enlargement also increased trade opportunities. In 2007, almost 80% of exports from the new member states went to the rest of the EU. Old member states also saw their sales to the new members increase to around 7.5% of their total exports in 2007, from 4.75% a decade ago.
Unemployment in the new member states declined to levels similar to those across the rest of the EU: around 7% in 2007.
This year, the twelve newest EU members are due to receive seven billion euros in communal development aid, and the European Investment Bank says it will lend them a further 11.5 billion euros.
Fears of protectionism
But the economic downturn has triggered protectionist tendencies in the 27-nation bloc, threatening to undermine the EU's benefits for its members from the single market.
Some of the poorer member states fear protectionism is on the rise in the older members of the Union, which can afford to spend billions of euros to protect their banks and industries.
"We should not let the crisis overshadow this uncontested success. United, we can shape the solution to global issues such as climate change or a new international financial governance," Economic Affairs Commissioner Joaquin Almunia said, adding: "Divided we will achieve nothing."
The EU will hold an emergency summit on 1 March, partly to discuss protectionism.
