Abstract: The aim of this paper is to find the link between intra regional exchanges and the economic growth of the CAEMC area. To achieve this aim, the temporal series of econometric was applied in consideration of the foreign direct investment, human capital, demography and the quality of the institutions as variables of control. Afterwards, the Johansen Test of cointegration had been applied to avoid a kind of deceptive regression backed by a model of errors adjustment. Contrary to common ideas broadly shared on the positive incidence of the integration on growth, the study concludes that the exchanges among CAEMC countries have a weak negative impact on the economic growth within the area.
