Tourism sector has become quite important in recent years due to its contributions to the balance of payments, employment and national income of both developed and developing countries. In order for countries to become a stronger global actor today, they need to increase their global competitiveness not only in the product markets and industry, but also in the tourism sector. In this perspective, in this study, which covers the period 2003-2017, the level of specialization and competitiveness in the tourism sector, which is a key role for the Turkish economy, were analyzed and "the Revealed Comparative Advantages" approach was used in the analyses. The Balassa index was used to determine the level of competition. In order to determine the level of specialization, the Net Trade index and the Export Import Ratio index were used. According to the results of the analysis, Turkey has provided expertise in the tourism sector and has a moderate competitive edge.
