The diversification of export commodities and the decentralization on the export of several limited products have reduced the country's foreign exchange earnings effect in global political and economical fluctuations, and this is why this issue is of particular importance. The main of this study is to examine the relationship between the diversification of industrial export goods and the volatility of foreign exchange earnings in Iran`s industry sector. For this purpose, seasonal data from 2002-2 to 2018-3 and using the NARDL method to determine the Rocket-Feather effect of diversification and concentration in industrial export have been used, and for the purpose of examining export diversification, the Hierarchical Index and Till Index have been used. The results confirm the asymmetric effects of diversification and concentration on instability of exchange earnings industry in the short and long run, so that in both models, diversity has less impact on the focus of industrial exports, so the diversification of export-oriented industrial goods has slowly stabilized foreign exchange earnings. While the concentration of export industrial goods has been strongly caused by the instability of exchange earnings. Also, the impact of global income on the instability of the industrial exchange earnings has been negatively achieved, thereby contributing to the stability of exchange earnings, while the instability of the real exchange rate, inflation rate is positive and instability have intensified. Also, the impact of investment in the industrial sector was negative but insignificant.

The main purpose of this study is to investigate the relationship between the export diversification in the top industrial sub-sectors and its impact on the volatility of foreign exchange earnings in Iran's industrial sector. Accordingly, quarterly data from 2002-2 to 2018-3 were collected in the top three industrial sub-sectors of the country and the autoregression method with distributed intervals was used for estimation. The findings indicate the positive effects of inflation and global income on short-term and long-term foreign exchange earnings instability and the effect of concentration index of base metals sub-sector on industrial foreign exchange earnings instability was positive and in non-metallic mineral products and workshop textiles has been negative and significant. Therefore, moving towards diversification in the metals sub-sector and focusing on the non-metallic mineral and textile sub-sectors will reduce the volatility of industrial foreign exchange earnings. Based on the results, it is suggested that the government reduce the instability of industrial foreign exchange earnings by granting facilities, setting export and import customs tariffs in industrial sub-sectors, while directing production in terms of diversification or decentralization.
