PurposeInnovation and sustainability are two key factors for retailers seeking a competitive advantage. However, the way in which the joint effect of both of these variables impacts consumer satisfaction is still unknown. To address this gap, based on the concept of sustainability-oriented service innovation (SOSI), the authors introduce a new construct named sustainability-oriented commerce innovation (SOCI) in the context of the retail sector.Design/methodology/approachThe relationships between the variables defined in this research were examined using a structural equations model for 510 customers of grocery retail establishments.FindingsThe authors find support for a direct positive impact of SOCI on customer satisfaction and an indirect impact through store equity. These chained effects are modified according to the client participation in the development of sustainable and innovative initiatives.Originality/valueThis research analyses the joint effect of innovation and sustainability in the retail context by introducing a new concept – SOCI – and a scale for its measurement whose psychometric properties are validated.
