Abstract:The purpose of this study was to examine the key characteristics of sustainable service innovation in the hospitality industry. We conducted a content analysis based on the interview records for 17 experts (including three academic scholars, three government officers and 11 top-level managers) with an average of 20 years of experience in the hospitality management domain in Taiwan. The analytical results conform to Amabile's (1988) componential theory of creativity and innovation and show that 11 characteristics are major indicators of sustainable service innovation in the hotel management field. These include the following characteristics: market position, customer satisfaction, service orientation, environmental thinking, employee involvement, incentive mechanism, human resource development, environmental services, cultural resource management, government policy and school education. Accordingly, using the integrated theory of sustainable service innovation and professional opinions from experts, we provide theoretical and practical implications for current and future trends on sustainability and innovation in the hospitality industry.
