Some of the most important variables (variable sizes) concerning the evaluation of the sport market role and their importance in national economies refer not only to economy but also to institutions and politics, and therefore the responsibility of states for economic development and long- term sustainability is conceptually becoming the responsibility of each national economy. Economic aspects of sport market and their relevance in national economies answer the questions of their own competitiveness on both national and global sport market. Sport has a significant and evergrowing influence on both Europen and national economies. This thesis gives an overview of the role and importance of sport for the member states of the EU and sumarizes the key indicators of its importance in the development of national economies. Based on the economic aspects of sport market and the analysis of two SpEA studies „on the contribution of sport to economic growth and employment in the EU“, this thesis attempts to draw conclusions and explain how to measure the contribution of sport to economy. Reliable data and evidence on the contribution of sports in the EU are needed to help shape the policy and raise profits in this sector. Communication on moving towards evidence-based sport policies.and the White Paper on Sport are based on evidence from Eurostat and a common methodology for measuring the economic impact of sport on national economies, via sports satellite accounts (SSA). From an economic point of view, the sports industry, following the rules of the process of production, exchange, distribution and consumption in a structural and functional sense, represents the area of capital placement, its relatively rapid reproduction and expansion, business space and high earnings so it directly manifests itself in the growth and development of national economies.
