Abstract
In the network of political and public administrative actors the public administration plays a key role. Countries previously influenced by socialism or communism, that joined the European Union in the two most recent accession waves, and are now undergoing strong change, are investigated to determine whether—and to what extent—public administrations influence transition processes to more democracy and market economies. With a regression analysis it is demonstrated that a qualitatively better functioning public administration makes a positive impact on transition, its effectiveness, and sustainability. The regression analysis also offers arguments for the view that public administrations are important actors when it comes to the implementation of EU standards.
