The present paper describes the Uzawa (1965)–Lucas (1988) type two-sector model of endogenous growth, in which morover goods and services sector emphasizes also the production of human capital, as well as simulates the time paths of macro variables assuming that the Iranian economy behaves under the hypothesis of denoted model. Therefore it's practiced on dynamic optimization and solving the control problem of maximization the present value of representative agent’s flow of future utility (due consumption) in infinite horizon subject to constraints in physical and human formation using the pontryagain's maximum princliple. Then, for the differential equations system obtained, the dynamics, the existence and determinacy of the steady state, analyzing also the balanced growth paths are studied in two cases parametric and numeric with estimated values for Iranian economy. By using Iranian economy available data in period 1974-2007 various coefficients have been estimated and time paths of GDP and other variables simulated. The results of this study indicate that on the balanced growth path the real GDP annual growth rate in Iran is about 4.7%. Furthermore, an increase in technological parameter for education sector and output elasticity with respect to human capital can makes increase in this rate of growth and economy moves to the higher balanced growth path so that this subject confirms the role and importance of human capital in economic growth.
