DIVERGENT CHARACTERISTICS OF DERIVATIVES OF STATE FISCAL SPACE: SEQUENCE OF TERMS

. Inconsistency of certain terms and concepts often become the key questions in scientific theories research. Semantic explanation of some definition can become a subject of the controversial discussions. In this case, the problem can be transformed into the practical area especially if some miscomprehension must be agreed in the legal field. Purpose. The article aims to define the key positions on the generalization of the essence of specific economic terms in the context of fiscal space exploration, to determine the corresponding conceptual apparatus in order to prevent the use of some definitions as synonymous ones, the concepts substitution, and the formation of inadequate reasoning, which can become the basis for false conclusions.Method (methodology). In order to reach the goal of the research we have used the different methods. They are the axiomatic method (one of the ways of deductive formation of fiscal theory when the system of key terms is formulated); the empirical method (to realize the theoretical analyses of key definitions, to consider fiscal space derivatives, to form the vision of their nature and to present the author’s definition). Results. Current trends of development of fiscal science have been analysed in the article. Problems of inconsistency of the conceptual apparatus have been considered. It has been proposed the definition of the basic terminology concepts. They are fiscal environment, sufficient fiscal space, optimal fiscal space, fiscal environment, etc. The necessity of rethinking the theoretical foundations of the formation of the modern theory and concepts of the fiscal space of the state in the context of the interconnection of its components has been emphasized. The main macroeconomic factors, which forbid formation of the positive fiscal environment in Ukraine have been outlined and analysed in the research. The factors, which influence its formation and functioning in the state, have been determined. The existence of an appropriate optimal space under conditions of fiscal expansion has been demonstrated and grounded. The phenomenon of "tax devastation", which arises because of an increase in the tax burden on the real sector of the economy, national production, and labour, has been investigated.
