The complexity of economic development processes causes that the level of diagnosis and interpretation of that growth is still unsatisfactory. Hence, it is not possible to precisely determine its course and probably the results of development processes. The accuracy of the development concept results from the complexity of the analysis of its determinants. Consequently, we can assume that a group of economic growth determinants in particular countries and during particular periods of time is initially determined by the institutional system whose individual elements are different in character, origin, premises and the rate of changes or decline, and the way in which they influence the process of development. Thus, the state as the main initiator of the institutionalization in the political and economic spheres and as the initial organization in the political structure and an indispensable subject in the economic sphere appears to be crucial.
