Abstract: In recent years, China's hotel industry has seen a significant growth. Major foreign hotel groups have also shifted their markets to China, which adds to the operating pressure on the domestic hotel industry. The focus of competition is mainly on the quality of external services. Regarding the research on the quality of service, scholars at home and abroad have focused on the quality of services of external customers and neglected the research on internal service quality. This article takes Guangzhou S Hotel as the research object, uses literature analysis method, questionnaire survey method, quantitative and qualitative analysis methods, and uses Internal SERVQUAL scale proposed by Hallowell et al. Finally, it discovers that Guangzhou S Hotel staff is insatisfactory with the training system, incentive mechanism, internal management support, internal service system, and corporate culture recognition. This article analyzes the reasons from these five aspects, and proposes corresponding improvement measures, which provides a certain reference value for the hotel to improve the internal service quality and human resources : hotel; internal service quality; improvement strategies; human resources人工翻译的,给别人报价都100元左右。我是二级笔译持证翻译匠。
