11 The 21st century is the arena of extremely dynamic and turbulent changes we have become not only witnesses but also participants of. They keep bringing newer and newer challenges for the functioning of the economies of individual countries and their regions, and the behaviours of enterprises - the basic elements of the subjective triad of each economy. Thus, the paper attempts to outline the background, causes and consequences of the changes in the bahaviour of contemporary enterprises, and justifies the necessity of the system reconstruction and the modernization of their structures in the face of crisis situations, the globalization challenges and the requirements of the New Economy. https://www.ijbed.org/details&cid=11 https://www.ijbed.org/cdn/article_file/i-1_c-11.pdf Volume 01 Issue 1 1 2013-03-01 2014-03-03 no Globalization New Economy economic crisis restructuring none 5377 6 0 Ryszard Borowiecki Cracow University of Economics
