description Efficiency, optimal allocation of sources depends on competitive performance of markets. To establish competitive markets, maintain and increase efficiency, it is necessary to exist different issues including complete definition of legal ownership, reduction of conventional and exchange costs, facilitating the flow of information among producers and consumers in the markets and also existence of facilitator rules concerning competition and anti-monopoly. In this research, we have collected the statistics of big industrial working places in 2007 and computed the concentration and monopoly indexes for 130 industries by using Hrefindhal – Hirshman and share of better firms indexes. In addition, we have evaluated the role of private and public companies in increasing and reducing the monopoly, and the effective factors in creating & sustaining of monopolies. Results from the research indicates the considerable concentration in Iran’s including in public & private sectors. The most important reason to establish monopolies in the country, either in public or private sectors, is creating input obstacles through laws and regulations.
