Today's global economic activity is characterized by the process of economic integration. Due to the internalization of business and abolition of restrictions on the movement of goods, services, people and capital, there has been an increase in the volume of international trade and investments, which both contribute to the economic growth. However, the global economy is (under the influence of economic globalization) becoming more and more integrated and dependent on the global market. It is international trade that contributed to the higher growth and productivity of the countries, which became more competitive in the world market through the trade integration and globalization of its specialized industry. This leads to not only economic, political, cultural and social connections and interdependence of the countries, but there is also a chance of big national economic sensitivity to crises that may occur in any part of the world and can have consequences for the entire global market. The statistical monitoring of macro and micro economic indicators at the regional and national level can be conclusive in determining the consequences of the membership in integration. This paper will analyze the influence of integrations on the example of the EU – 28 countries. As the largest economic integration at the moment, EU – 28 is strengthening its leading position in the world economy. Market liberalization and free movement of goods, services, people and capital have created opportunities for both internal and external economic growth and development of the EU – 28. By comparing transition countries (in the region) with the Republic of Croatia, the author of the work analyzes the impact of the integration on the economies of member states. Also, after the analysis of the economy through some macro and micro economic indicators, the author describes the current situation of the Republic of Croatia and proposes possible strategic directions of its economic development.
