Sustainable tourism is the idea of managing the negative impacts or potential for serious harm to the economic, environmental, or social elements of a destination, and thus reaching the goals of sustainable development. This research benchmarks the sustainability of 111 tourist destinations throughout the world, using an advanced integration of a two-stage network DEA under the meta-frontier concept, directional distance function, and network-based ranking methods. The empirical outcomes of these analyses clarify that the sources of sustainable inefficiencies are the self-production process and the technology gap among the tourism regions, rather than the capacity of utilizing the input resources or maintaining the production outcomes. The network-based ranking emphasizes the sufficiency and deficiency of each place, and provides a map of reference among destinations. Based on these, the article reports some managerial suggestions, theoretical implications, and future research directions.
