This article aims to study and evaluate the possibility of developing cooperation and trade between Iran's manufacturing industries and the countries of the Persian Gulf Cooperation Council.Two important spectrometers; changes in the global competition structure of factory industries; That is, "concentration ratios" and "Herfindahl-Harishman index" and the possibility of developing cooperation and trade; That is, "advantage and specialization indices" and "performance indices" for the member states of the Council and Iran during the period of 2000-2021 have been used for measurement and evaluation.From the study, analysis, evaluation and calculation of the changes in the structure of competition in the global production of factory industries and the position of the two groups of the world's leading countries and emerging and developing industrial economies, emphasizing the share, rank and position of Iran and the member countries of the PGCC. the following results can be noted:The study of developments and changes in the global production structure of 22 industries over the past two decades indicates that the global production structure of many industries (16 industries), including low-tech, user- and resource-oriented industries, has become more exclusive.Also, from the study of the share, rank and position of Iran and the member countries of the PGCC in the global production structure of industries, it is concluded that these countries have been influential players in resource-oriented industries such as refineries, chemical products and non-metallic minerals during the period, but in knowledge-based industries and Even the user has the optimal distance.Right now, from the range of 22 industrial industries and 6 member countries of the Council, only Saudi Arabia is in the first priority in more than half of the industries in terms of capacities, facilities, diversity and range of industrial productions, the most areas of possible development of cooperation and trade with Iran.
