This study examines the perceived importance of corporate social responsibility (CSR) attributes of Hong Kong hotel employees and their hotels’ performance on those attributes, and to determine underlying performance factors that ultimately lead to the perceived overall CSR effectiveness of hotels. The importance–performance analysis results show that Hong Kong hotels generally performed well on 17 out of the indicated 30 CSR attributes. Furthermore, the attribute “promote innovation in products and services” was considered to be overkill, and another attribute, “demonstrates a commitment to the environment,” requires the immediate attention of hotels. Six performance factors were extracted and Hong Kong hotels performed best in the area of finance. The factors “state of affairs” and “novelty” positively and significantly affected employees’ perceived overall CSR effectiveness of their hotels. Almost 70% of the respondents agreed that Hong Kong hotels had been effective in carrying out their CSR. Hotels in Hong Kong should find our study results helpful in pinpointing CSR attributes considered of various importance and performance levels from the perspective of one of their important stakeholders, their employees. In particular, the relatively low awareness toward the environment of both the employees and the hotels should alert the hotel management to invest greater efforts in environmental protection
