Under this circumstance, stronger competitiveness in leisure is of great importance in efforts to enhance national competitiveness since it is one of necessary factors in the transformation from a labor-intensive industrial society towards a future society. This study, based on Porter\'s Diamond Model(1990) and the IPS National Competitiveness Research Report evaluating 66 nations\' competitiveness, examines major factors that affect a nation\'s competitiveness in leisure and produces Leisure Competitiveness Index. This study aims to identify the current status and Korea\'s leisure competitiveness in comparison with Strong-Medium Countries from IPS National Competitiveness Research Report and highlight the critical relationship between the national competitiveness and its leisure competitiveness. The study shows that Korea ranks lower than its competitor, Strong-Medium Countries in Leisure Competitiveness Index and it also shows imbalance of factors that are key to stronger competitiveness in leisure. These findings have greater significance as they serve as a standard for a government to resolve problems in its leisure policy and conditions and come up with an improve policy in the future.
