This study examined the casino research trends in Korea using the semantic network analysis. A total of 517 casino-related studies identified through RISS search, were used for the analysis. Both frequency of occurrence and centrality analysis results showed that research topics related to human resource management, casino customers, and casino businesses ranked the top. Among them, the influence of human resource management related keywords was the largest. The result of comparative analysis of casino research trends divided them into two periods: the first half (2008-2013) and the second half (2014-2019) showed that the human resource management field was the most important topic of Korean casino research at all times. However, keywords such as 'integrated resort', 'corporate social responsibility', 'organizational citizenship', and ‘responsible gambling’ that were not in the first half appeared in the second half suggesting that the topics of Korean casino research are also changing due to changes in the casino industry and social needs. Finally, this study suggested that despite the quantitative increase in Korean casino research, the diversity of research topics is very limited. It is necessary to initiate creative research design in various aspects beyond existing research.
