The tourism sector has a significant effect on foreign trade relations of countries. This effect is discussed with the concept of intra-industry trade. In this study, intra-industry trade of Turkey and some selected countries has been studied to be analyzed with Grubel-Lloyd (GL) Index. In the country choice Germany, Russia, United Kingdom, Bulgaria, and Georgia were preferred because these countries send the highest number of tourists to Turkey. Thus, within the scope of selected country examples, Turkey’s tourism sector has been examined as structural. When 2000–2013 average GL Index value was examined, Georgia came out as the country with the highest index value. Georgia is followed by the United Kingdom and Bulgaria. When GL Index was analyzed as both annual and average of the period, Turkey had the lowest value that was seen. The most important reason for this is that the gap between Turkey's international tourism revenues and expenditures is high.
