This study investigates the relationship between tourism destination competitiveness and the competitiveness of international hotel firms using an integrated approach based on Porter (1990). A mediation model is employed to link destination competitiveness, efficiency and firm competitiveness. Global technical efficiency (GTE), pure technical efficiency (PTE) and scale efficiency (SE) are estimated through data envelopment analysis (DEA) techniques. The results confirm a positive relationship between destination competitiveness and firm competitiveness, but efficiency does not play a mediating role linking both.
