A review of social roles in green consumer behaviour

Despite the broad interest and rapid increase in studying green consumer behaviour (GCB) from a social perspective, related articles have been presented in a piecemeal fashion and have lacked a review of social roles in GCB. Additionally, the research focus may differ from the influence of digital technology. Therefore, this study draws on a review of 439 GCB articles that focus on social roles and utilizes both quantitative and qualitative analyses to provide a general picture of theories, social factors, research topics and topic trends with a specific emphasis on the research differences between the traditional and digital contexts. The findings indicate that the GCB field has experienced exponential growth since 2014. Subjective norms, social influence, culture, marketing influence and social media influence are the main drivers of GCB. Eight research topics are identified, among which topics on the theory of planned behaviour (TPB) and the theory of consumption values (TCV) maintained high popularity. Furthermore, the TPB is more prevalent in the traditional context in which scholars prefer to predict GCB using macrosocial factors, such as policy and culture. In comparison, signal theory and commitment-trust theory have received more attention in the digital context in which trust is vital. Research interests in online platforms and green hotels have recently increased in the digital context. Gaps and suggested directions for future studies are further identified.
