摘要：Our paper provide evidence on the relationship between export diversification and economic growth for the fifteen (15) countries of ECOWAS states from 2005 to 2015. We analyzed the effect and the nature of the relationship between Export diversification and economic growth. Using the dynamic panel data estimate method, we found that export diversification impact economic growth in ECOWAS states. However, the evidence of the link between export diversification and economic growth is non-monotonic (humped-shaped) relationship, which means that countries in ECOWAS can intensify export diversification in certain point at critical concentration export value=0.52 level, where income start to fall with export diversification portfolio. From that point the specification (concentration) should be intensify so as to increase income and pursue the higher growth.
