Social media has become a site of social (re)construction, continuously constituting new realities, especially in the context of corporate responsibility (CR) communication. Morsing and Schultz’s (2006) CR communication strategies, a foundational publication of the field, precedes the age of social media and the study of communicative constitution of CR (see Schoeneborn’ s work). In response, we revisit CR communication strategies through a communicative constitution lens, by studying fifty European and Chinese companies’ CR communication on social media.
