Assessing the Tourism Efficiency of European Countries Using Data Envelopment Analysis: A Sustainability Approach

This study assesses the tourism efficiency of European countries from a sustainability perspective, using variables representing demand sustainability, environmental sustainability, and the socio-economic impact of tourism. The results of the study show that out of 31 countries, 16 achieved the highest possible efficiency score. A significant challenging issue that can be highlighted for most European countries is the very short length of stay of tourists, except for in some Mediterranean countries, such as Malta and Croatia. Countries in Central/Eastern Europe, predominantly, have very high values of greenhouse gas intensity, which adversely affects the environment. Therefore, policymakers in these countries should work on improving environmental policies in order to prevent further environmental degradation. Also, strategically increasing length of stay can have a positive impact on various dimensions of sustainability, as length of stay is associated with more dispersed visitor travel patterns, reduced environmental impact and higher tourism expenditure. The projected input and output values for individual countries can provide insight into possible areas for improving tourism efficiency, and represent valuable information that policymakers can use when making long-term decisions regarding future tourism development.
