The paper introduces the panel auto regressive distributed lag/pooled mean group (ARDL/PMG) to reach its purpose. The export diversification measured by Theil index. The Pedroni panel cointegration test confirms that the variables are cointegrated, whereas PMG estimates indicate a positive significant long run relationship between export diversification and real gross domestic product (GDP) growth, no significant effect of export diversification in the short run. | Modeling the exports diversification in the oil countries growth The case of gulf cooperation council countries
