The subject of investigation is the investment potential of the territory in the context of the market economy. The purpose of investigation is the development of scientific regulations and methodical support of formation of the effective mechanism of the state regulation of the investment potential of the territories of Ukraine on the basis of evaluation of the role of the regional investment processes in the national economy; and the justification of the directions of increasing the effectiveness of its functioning in the context of the market. The methods of research are system, process and complex approaches, analysis and synthesis, comparative, economic statistic, index, graphic, dialectical and logical methods, the method of scientific abstraction, historical and logical approaches, qualitative and quantitative analysis, economic mathematical methods and monographic method. The practical importance of the obtained results consists in that the basic conclusions and suggestions formulated in the dissertation research have extended the following: the theoretical basics for problem solving of formation of the effective mechanism of the state regulation of the investment potential of the regions, the development of directions of state influence on the improvement and the development of the investment activity, the concrete methodical recommendations for evaluation of the investment potential of the territory, the modeling of formation of the active investment policy of the state. The scientific novelty of obtained results is that first the conception of development of the mechanism of the state regulation of the investment potential of the region has been developed. The conception of the investment potential, the essence and content of the state investment policy, the system of principles of development and realization of the mechanism of the state regulation of investment activity, the regional mechanism of the state regulation of investment activity, the model of formation of the mechanism of the state regulation of investment activity, the factor system generated on the basis of principles of sufficient diversification, minimal sufficiency and goal orientation, have been improved. The classification of methods of the state regulation of investment activity, the methodical approach to evaluation of the investment potential of the territory, the methodology of evaluation of the investment effectiveness in the innovation on the basis of economic mathematic modeling, have been further developed.
