This study examined the effect of structural change on economic growth in ECOWAS countries between 2004 and 2023, using panel autoregressive distributed lag estimate. Findings showed that structural change (SC) has a negative insignificant effect on economic growth in the short-run, while in the long-run, it has a positive significant effect on GDP. In the short- and long-run, employment (EMP) and labour productivity (LP) have positive significant effects on the economic growth in ECOWAS countries. Domestic capital (Kap) and human development (HDI) have positive significant effects on economic growth in the short- and long-run, respectively.

However, a long-run relationship was established between structural change and economic growth in ECOWAS countries within the period of study. It is therefore recommended that government should streamline structural change to tackle the present challenges in order to have positive effects on economic growth in the region. Government should intensify efforts to improve on domestic capital (Kap) in order to enhance the economy of the region, paving ways for job creativity among the jobless.
