Observing the expanding and high share of export of travel services in both GDP and total export of services in Mediterranean countries, we focus our research on travel service export in twelve countries from 1998 to 2018. We investigated both short-term and long-term significance of export of travel services for GDP growth in Mediterranean countries using the VAR and VECM model and the fixed-effects panel OLS model. In our analysis of significance of export of travel services on current account balance, we applied an accounting approach. Our application of the fixed-effects OLS model on the panel data with GDP growth rate as the dependent variable has shown that, in the short run, export of travel services has a positive impact on GDP growth. In the long run, Granger causality based on block exogeneity Wald tests evidenced that export of travel services has a positive impact on GDP growth, but only at the 10% significance level. Following the accounting approach in our analysis of impact of export of travel services on overall current account balance, we evidenced a strong relevance of export of travel services in achieving current account balance equilibrium.

旅行服务出口对地中海国家经常账户余额和增长的影响

观察地中海国家旅游服务出口在GDP和服务总出口中的增长和较高份额，我们将研究重点放在1998年至2018年间十二个国家的旅游服务出口中。我们研究了短期和长期意义VAR和VECM模型以及固定效应面板OLS模型对地中海国家旅游服务出口对GDP增长的评估。在我们分析旅行服务出口对经常账户余额的重要性时，我们采用了一种会计方法。我们在以GDP增长率为因变量的面板数据上应用固定效应OLS模型显示，短期内，旅游服务出口对GDP增长具有积极影响。长期来说，基于块外生性的格兰杰因果关系Wald检验表明，旅游服务出口对GDP增长具有积极影响，但仅在10％的显着性水平上。在对旅行服务出口对整体经常账户余额的影响进行分析的会计方法之后，我们证明了旅行服务出口对实现经常账户余额平衡的重要意义。
