The objective of this study was to use the perceptions of internet users to analyse the effect of the social, economic and environmental dimensions of corporate social responsibility (CSR) implemented by hotel establishments in order to determine whether those dimensions are perceived by consumers. Our analysis was based on a sample, distributed by age, sex and province segments, obtained from the Andalusian population between 16 and 74 years of age who are users of travel websites (e.g., TripAdvisor, Booking) and hotels corporate websites. A questionnaire was used to investigate each latent factor related to the three main dimensions of CSR that may affect the perceptions of accommodation service consumers. The questionnaire was statistically validated and developed in previous economic studies in this field. The data were analysed using Partial Last Square (PLS) methodology. The results confirm the validity of the three dimensions analysed, although consumers appear to play more relevance upon economic and environmental factors than upon the social components of CSR.
