The purpose of this study is to classify an Integrated Resort Casino (hereafter IR) according to economic factors and then derive the resulting multipliers. The study examines IR competitiveness using an Input-Output Model (hereafter I-O Model). Based on previous I-O studies and I-O tables obtained from the Bank of Korea (2014), IR is classified into three major sectors: 1) casino, 2) tourism, and 3) convention with a further six sub-sectors being: shopping, restaurant, accommodation, convention, entertainment, and casino. This study derived six multipliers of output, income, value added, indirect tax, employment, and importation based on 27x27 industrial sectors where IR was disaggregated into six sectors. Results reveal that output multipliers of IR were relatively lower than in other sectors, whereas income and employment multipliers of IR were higher than in general and export sectors. The findings indicate that IR is more likely to generate income and employment, implying a labor intensive industry. The results of backward and forward linkage effects indicate that IR influences and receives impacts from other sectors moderately. Also, IR was found to have a strong effect on foreign exchange earnings as compared to major expert industry. Implications were provided in the conclusion section based on the results of this study.
