In this study, Constant Market Share Analysis is used in order to determine the competitiveness of Turkey and its competitors, which are the main olive oil producers, in the USA, Australia, Canada, Brazil and Japan's markets between 1990/94 and 200/04 periods. The analysis shows that during the period covered Italy is the most competitive in the destination markets. Greece and Turkey follow Italy. In the same period although Spain's export towards destination markets is increased, its competitiveness is affected adversely due to decrease in its market share. Turkey's success in sustainable and permanent international competitiveness in olive oil depends on production, organization and trade policy.
