In order to achieve this purpose, annual data were collected from the reports of Tunisian Central Bank for the periods between 1970 and 2016 was tested by using co integration analysis of Error Correction Model. According to the result of the analysis, citrus exports do not influence on economic growth in the long term. However, empirical results show that there is a positive unidirectional causality from citrus exports to economic growth in the short run. These results provide evidence that citrus exports, thus, are not seen as source of economic growth in Tunisia because the miserable economic strategy. For this reason, it is very important to make new reforms and to create robustness strategies to refine investment and trade strategy in this sector, so it can support economic growth in Tunisia.
