Determining the economic growth driving forces has a paramount importance in economic studies. Early studies have been suggesting physical capital accumulation as the main driving force of growth. However، the recent studies try to resolve the flaws of the economic classical views on growth by expanding and extending the concept of capital equipment and machinery areas to a wider range of human knowledge، on one hand، and institutions، rules and regulations as social capital، on the other. In fact، this branch of economics has become more prevailed. The present study، using Hausmann، Pritchett and Rodrik (2005) approach، aim to investigate the impact of rules and regulation reforms of developmental plans on the acceleration of Iran economic growth over 1338-1386 (1960-2008) period. The results of three methods including Gompit،Logit and Probit models show that economic reforms of the developmental plans in Iran's economy had a significantly positive impact on growth.
