It has been determined that at the current stage of global economy development such factors as science, technology and innovation play an important role in formation of a competitive economy. It has been established that the overall funding level with respect to science proves one of the key characteristics of an innovative country, and therefore NIS performance analysis was carried out based on the national expenditure indicator regarding research and development as well as on the country's position in the Global Innovation Index. The analysis carried out showed that the NISs of certain countries were more efficient than those of the others due to peculiarities of the innovative system elements that can be further referred to as determinants of building an effective national innovation system of a country.
