Resumen
Political and economic changes in the former socialist countries in the early 90s of the 20th century have not only opened up possibilities for the future democratic development of these countries, but also an opportunity for solving economic, political, social and environmental situation in the context of building a new, market economic system. The unfavourable environmental situation in Serbia is caused by many factors, among which frequent changes in the economic system in the past and inadequate economic and system solutions occupy a significant place. A critical approach to the impact of economic system solutions to the political and institutional arrangements for environmental protection in the SFRY, FRY, Serbia and Montenegro and RS is therefore a suitable starting point for understanding the importance and the need to take a more active approach to solving environmental problems in Serbia. It is also a goal of this work. In addition, solving the problems in the field of environmental protection is crucial for achieving sustainable development and improving the competitiveness of the Serbian economy. Key Words: economic system, reforms, environmental policy, Republic of Serbia
