Abstarct: Intellectual capital is defined as "the ability to transfer knowledge and intangible assets to resources for wealth creation." Knowledge increases the wealth of the country if its importance is known and is different from the existing work practices, and Knowledge transfer is essential in this regard. Intellectual capital can be recognized as knowledge-baxsed assets that underpin the growth of the country. In recent decades non-financial assets that constitute intellectual capital (IC) are the most important source of wealth creation and national progress. Knowledge and information are the main feature of nations seeking development.within the frxamework of this study, three hypotheses were examined. According to the first three hypothesis, with increasing intellectual capital, productivity increases and increases with increasing productivity of economic growth. Of course, this effect does not happen quickly and is delayed. . According to the second hypothesis, when human capital increases, intellectual capital also increases and according to the third hypothesis, intellectual capital doing activities in a new and better way leads to higher productivity.this research examines the impact of intellectual capital on Iran's economic growth using the dynamics model of the system. The dynamic model of the system is one of the best scientific methods for complex models, such as nolinear dynamical systems, and is therefore suitable for monitoring and evaluating the effects of intellectual capital on economic growth. The study period is 1380-1394 and its simulation is planned until 1410.The econometric model is also used in this research. This result was also obtained from modeling and we can say that modeling was confirmation of the system dynamics model.
