Due to the complex nature of the relationship between the tourism industry and GDP, economists have not reached a unanimous consensus on how these variables influence each other. Therefore, this study was conducted to examine the impact of the tourism sector on GDP. The research focuses on Turkey, Greece, Italy, Spain, Egypt, and Cyprus over the period 2003–2022. To analyze these relationships, a regression analysis was carried out using the OLS method in STATA-14. The results indicate that all regressors are statistically significant, demonstrating that the development of the tourism sector contributes to GDP growth.
