From 1970, the concept of ecotourism is introduced, lots of studies in ecotourism appeared. Review these studies are necessary for future ecotourism studies. Some review studies on ecotourism are existed. However, these approach also limitation of subjectivities and some sorts of papers has not been reviewed. This study use keyword network analysis which is used as big data analysis to overcome the limitation. Foreign 2455 studies and domestic 163 studies which have ecotoursim in keywords, are analyzed for reviewing. As a result, 3 cluster(‘Sustainable tourism development’, ‘Ecological conservation’, ‘Ecotourist analysis’ appeared, in ecotourism studies. In addition, this cluster has deep relationship with region. ‘Sustainable tourism development’ is related to Eurasia, Australia, Europe. ‘Ecological conservation’ is related to Africa. ‘Ecotourism analysis’ is related to North America. Especially ‘Resident participation’, ‘Stakeholder’ are appeared many times in Asia region. These results show that ecotourism studies are interpreted in regional contexts. It means that although only one word ‘ecotourism’ is used in different contexts, regional approach are needed for exact use. In Korea, the keywords are focused on ecotourists and developments. As Korea has lots of ecotour village, resident participation studies have to be supplemented.
