After decades of domination of centrally-planned economic system, countries of Central and Eastern Europe began a long and difficult process of economic transition to market economy. This process consists of economic stabilization, trade liberalization, major changes in social system, development of sound financial system, and many more factors.
Most of economists agree that the most important, and at the same time the most difficult task to face for post-communist economies is to make thorough structural changes of the economy.

It is most important, because the structure of economy inherited from communist systems is ineffective and weak, unable to exist without certain political support, which is contradictory to idea of competitive, liberal market economy. And it is most difficult, because however it is possible to change the law, the monetary or fiscal policy comparatively quickly in administrative way, structural changes can not be made by simple governmental decisions. It takes time to draw attention of investors to domestic enterprises, and the only thing that political authorities can do is to prepare a good framework for entrepreneurs, and not to oblige them to do anything.
