Today, the positive impact of entrepreneurship in the economy has been globally accepted. Entrepreneurs could provide efficient techniques to face with upcoming economic challenges. In this paper, we first investigate the effect of entrepreneurship on growth of economy over the period 2005- 2011. Then we study the impact of four factors including Gross domestic product per worker, Growth in capital per worker, New firm creation and Technological innovation intensity on economic growth. The proposed model of this paper uses ordinary least square technique to investigate the relationship between four independent variables and economic growth. The results show that gross domestic product per worker is the only variable, which is statistically meaningful when the level of significance is five percent and the impact of other three variables including growth in capital per worker, new firm creation and technological innovation intensity are not statistically meaningful. In other word, as we see a 1% increase in gross domestic product per worker we could expect 8.712% increase in economic growth.
