The purpose of this study was to identify current research trends and clarify the changing direction of studies on luxury hotels. Scholarly studies published between 1994 and 2014 were examined through content analysis, using such keywords as “luxury hotels”, “deluxe hotels”, “upscale hotels”, “high-end hotels”, and “four- or five-star hotels”. The contributions were then screened to focus on luxury hotel-centered topics. The search revealed 70 qualified scholarly research articles. Conceptual studies were limited, with empirical studies representing a majority of the luxury hotel researches. The luxury hotel researches that were identified were categorized into nine groups by research themes: marketing, human resources (HR), finance, strategic management, technology, service quality, food science, tourism and others, with marketing, HR and technology being the most popular research themes. Analysis of methodological trends in luxury hotel research indicated that the majority of the researchers utilized quantitative methods employing various statistical analysis techniques. Overall, luxury hotel research is still limited in the number of publications and diversity of research topics. This study was the first comprehensive content analysis on luxury hotels conducted to date. The findings of this study may provide future researchers and academicians with new insights based on past study as well as ideas for future research. It is hoped this study will contribute to the development of a reliable knowledge base from which practitioners may inform plans and action regarding future luxury hotels.
