Knowledge development and accumulation are important sources of economic growth and development and Learning is one of the effective factors in the development and accumulation of knowledge. Learning reduces the average cost over time along with increasing cumulative production. The chemical industry plays an important role in the country's economy due to its high value added, product diversity and employment. The objective of this study is to analyze learning by doing in Iran's chemical industry at the level of four-digit ISIC codes using panel data during the period 2011 to 2015. For this purpose, the learning curve was estimated using the panel data technique, assuming a constant return to scale. The finding indicate that learning has been achieved in Iran's chemical industry and the slope of the learning curve, ie the effect of learning in all sub-sectors of Iran's industry, as expected, is negative and equal to 0/86. The results indicate that the learning effect is different in the sub-sectors of Iran's chemical industry, but it is close to the average learning intensity.
