Triple bottom Line(TBL) is a comprehensive framework to evaluate the sustainability of an organization by integrating the triple important dimensions of economic, environmental, and social factors. This study analyzes the effects of the TBL factors on the performances of cruise ports by developing a linear regression model. A set of the time-series data of 15 years for various variables on the performances of major Korean cruise ports is used for the study. All the independent variables are grouped into three to form an analyzable data set within the TBL framework, and the statistical results are analyzed to show the impacts of the TBL factors on the cruise ports’ performance and sustainability. This study also suggests some policy implications important to develop major Korean cruise home ports for sustainable Korean cruise industry.
