The purpose of this study is to derive priority and relative importance of each evaluation attribute for the integrated resort impact evaluation. First, we examine the concept, characteristics, and current status of the integrated resort. Second, we review previous studies of the factors influencing complex resorts. Third, we derive the priority and relative importance of each attribute of the integrated resort impact assessment based on expert surveys targeting experts in tourism and integrated resorts. Fourth, we present the implications for sustainable growth of domestic integrated resorts based on the research results. In this study, weights were derived based on the method of stratification analysis. First, the integrated resort impact evaluation index was classified hierarchically. Second, input data was collected through pairwise comparison. Third, the relative weight of the pairwise comparison elements were estimated using the eigenvalue method. Fourth, the weights of the evaluation items were finally derived by synthesizing the relative weights of the decision-making factors. As a result of the analysis, the most important factor for evaluating the impact of the integrated resort is the economic impact evaluation, followed by tourism impact assessment, social and cultural impact assessment, and environmental impact assessment. Priorities for each detailed indicator were also derived and presented. For sustainable growth of the integrated resort in the future, it is necessary to consider the introduction of the integrated resort impact assessment, because it can be one of the tools that can enable sustainable growth within the region, such as maximizing the positive impact that it may have and minimizing or eliminating the negative impact that may occur. In this respect, the results of this study are expected to contribute to companies that develop and operate integrated resorts, as well as policy makers and government officials who want to promote related policies.
