The abundance of diverse and varied tourism economic impact studies can be overwhelming for new researchers in this field. The extensive and heterogeneous nature of these studies often creates confusion regarding the specific study topic, the relevant location, and the appropriate assessment models to employ. This paper employs the systematic literature method, co-occurrence network analysis of author keywords, and crosstable analysis to review 70 articles in the Scopus database from 1988 to April 2021. The result shows that tourism economic impact assessment topics can be grouped into tourism demand and factors affecting tourism demand. Locations of studies consist of nations, regions, cities, towns, and communities. Primary assessment models are Input-Output, CGE, TSA, and SAM; the CGE model and SAM have been applied in nations and regions; TSA has been applied to nations. The Input-Output model can be effectively utilised at different levels, including national, regional, and local scales, encompassing countries, regions, and towns. This study offers a comprehensive panorama of study topics, locations, and appropriate measurement models for economic impact assessment, enabling scholars to delve into further research with a clear understanding and direction.
