Research background: Importance of intangible resources for country's economic growth is widely recognized. However, empirical evidence of this influence is hard to show due to measurement limitations of intangible resources. Majority of empirical studies concentrates on the analysis of a specific type of intangible resource's influence on economic growth. National intellectual capital concept provides background for an integrated assessment of the country's intangible resources. This new approach enables the estimation of intangible resources' influence to economic growth in a more complex way. Purpose of the article: a) To examine various scientific approaches of the national intellectual capital and its impact on the economic growth; b) to offer a measurement model of the national intellectual capital influence on economic growth; c) to evaluate the specific European Union countries' intellectual capital's effect on their economic growth. Methods: Econometric analysis; refined factor value computation method using the standardized regression coefficients; the SAW method; expert evaluation, cluster analysis; correlation and regression analyses. Findings & Value added: A review of the economic growth theories showed that structural components of intellectual capital (human capital, structural capital, social capital, relational capital) in economic growth theories are analyzed as key determinants of economic growth. Our proposed research methodology consists time lag between variables and this let us evaluate casual relation. Empirical analysis of 25 European Union countries' intellectual capital's effect on their economic growth rate revealed that national intellectual capital and the countries' level of economic development have statistically significant impact on economic growth rate. The analysis of intellectual capital components' influence on economic growth rate of 25 European Union countries showed that only human capital and the level of economic development have statistically significant influence. A more comprehensive human capital's influence on economic growth analysis revealed that 63.1 percent of the long-term economic growth rate in 25 European Union countries can be explained by differences in their economic development level and differences in educational achievement factor values. Moreover, analysis of national intellectual capital effect on economic growth in separate clusters allowed to identify influence differences in each group of countries.
Nowadays intangible assets are especially important in every company and can help to increase a company's value added. The importance is so huge that many companies invest more money in intellectual capital than in material assets. Why has this happened? Scientists answer this question very quickly and easily - many companies have already been disappointed and damaged by their materials, goods, equipment, buildings, cars, machinery that cost a lot of money but do not give effective productivity. On the contrary, intellectual capital that usually costs only the salary of an employee brings significant benefits. The research purpose is to evaluate the cohesion between intellectual capital and a company's value added and to provide the model of this cohesion. The methods used are analysis of scientific literature, GBN matrix method, expert evaluation, average comparison method, and Kendall's coefficient of concordance. Scientific aims: to reveal the cohesion between intellectual capital and a company's value added; to introduce a model of a company's value added and its intellectual capital; to demonstrate the results of expert evaluation on the model of intellectual capital and a company's value. The findings are as follows: intellectual capital is considered as a unit of social capital, communicational capital, and psychological capital; intellectual capital has a huge influence for the growth of a company's value added; employee motivation is the most important factor either for the growth of intellectual capital or a company's value added. Conclusions: expert evaluation was performed in order to investigate the importance of intellectual capital factors for the growth of intellectual capital itself and a company's value added. Experts were taken from two areas: business environment and academic environment. It is possible that experts from other environments could answer the questions in a completely different way, and this model could be improved even more.
