摘要：In this paper we investigated the impact of exports and imports on the economic growth of Tunis over the period1977-2012. The study used Granger Causality and Johansen Cointegration approach for long run relationshipUsing Augmented Dickey-Fuller (ADF) and Phillip-Perron (PP) stationarity test, the variable proved to beintegrated of the order one 1(1) at first difference. Johansen and Juselius Cointegration test was used todetermine the presence or otherwise of a cointegrating vector in the variables. To determine the direction ofcausality among the variables, at least in the short run, the Pairwise Granger Causality was carried out.Economic growth was found to Granger Cause import and Export was found to Granger Cause import. Theresults show that there is unidirectional causality between exports and imports and between exports andeconomic growth. These results provide evidence that growth in Tunisia was propelled by a growth -led importstrategy as well as export led import. Imports are thus seen as the source of economic growth in Tunisia.
