Market advantages and leadership of enterprises are increasingly becoming the result of the effective use of unique intangible factors. With the successful development of consumer and structural capital, which are components of intellectual capital, it is possible to achieve a significant synergistic effect, expressed in the growth of the country’s overall intellectual capital and the intellectual capital of individual economic entities. The structured value of IC has a less optimal effect than the average, which is due to the heterogeneity of the returns on the structural elements of IC. The greatest impact on economic growth is exerted by consumer and structural capital. The use of intellectual capital-such as human, organizational, and consumer qualities-enhances economic value when their synergy occurs. The balance among these types of capital, especially in critical moments, can cause a system to shift from gradual growth to sudden change or vice versa. Keywords: economic growth, synergistic effect, intellectual capital, intangible assets, model.
