Hospitality Industry is experiencing a recovery after a hit lasting for almost 2 years by the world pandemic. Different from other sectors, world hotel sector, which was also suffered a great loss, has been thriving by using the latest technologies into daily operation before, during and after pandemic to improve service quality to win more profits. The main technologies in hotel sectors contain artificial intelligence (AI), big data and automation. The service areas include check-in process, room service, pick-up service or parking service, etc. Researches have been made on many luxury hotels that have the financial capability to apply such technologies and proved that this application is conducive to hotel thriving. However, few researches have been made on focus of Chinese hotel sector, regardless of the significance of the contribution of Chinese hotel industry in the world. To address this research gap, this research puts emphasis on Chinese high end hotels, including Pullman Shanghai, Grand Millennium Beijing and Royal Garden Hong Kong, to analyze the impacts of application high technologies including AI, big data and automation on luxury hotel development. By using the quantitative survey method, this research collected data from 215 customers to acquire their feedback from application of high technologies in the three hotels. The key findings are that employment of advanced technologies of AI, big data and automation in Chinese luxury hotels are positive to their thriving and flourishing. However, the limitations were that Chines other levels of hotels were not paid as research targets and hotels in other countries are not studied either. Thus, the suggestion was that hotels, including all levels, should apply the three high technologies in their daily operation to achieve better development in the long run.
