Moreover, in this study sought to investigate the extent of monopoly power by using Panzer- Rosse non-structural approach. To meet this ends the data of 131 Iran’s 4-digit industries over the period of 1996-2007 were used. Results indicate that more industries in Iran had higher concentration than average and the extent of entry barriers were very high. Also, in Iran’s industries economies of scale were not exploited. In addition, the results of Panzar- Rosse model showed that Iran’s industries market structure were not competitive. %U https://pajooheshnameh.itsr.ir/article_24520_32bd0164c5e6846fdc18fc182d026fdb.pdf
