The scientific research is devoted to the dissemination of the utility method to research on socio-economic processes in the scientific and technical sphere. It demonstrates that not the maximization of R&D costs and even not the resulting scientific and technical information, but a change (improvement) in the structure (quality) of GDP should be considered to be the target (utility) result of its functioning. At the same time, to quantify the structure of GDP, the indicator of the economic system processability level is proposed. As another utility criterion for assessing its scientific and technical validity, an increase in the utility factor of R&D costs is justified, and its calculation procedure is defined. Based on the analysis of statistical information of the development of the scientific and technical sphere of the developed countries, it was revealed, that the utility characteristics of its functioning are much more significant than the conventional cost indicators, such as scientific intensity of GDP etc. Based on the above, the recommendations are given on the management of the scientific and technical sphere with regard to the strategy of the accelerated technological development in Belarus and its friendly countries.
