Awareness of strategic entrepreneurial orientations (SEO) has grown in sustainability research in small and medium-sized businesses (SMEs), and the extant literature includes review studies concerning SEO. Despite the existence of these studies, in the Jordanian context, more research is needed about a parsimonious model that includes the underlying mechanisms linking SEO to multiple sustainability performances. Given such a gap, this study proposes an updated conceptual model of SEO using the Resource-Based View theory (RBV) and Social Capital Theory (SCT) as the theoretical underpinnings. Specifically, this research links SEO to Jordanian SMEs sustainability performance, like economic, environmental, and social practices, through the mediating roles of sustainable supply chain management (SSCM). In addition, a relevant literature search highlights three indicators of SEO: innovativeness, risktaking, and proactiveness. This reviewed conceptual framework was created through a process of qualitative analysis including a synthesis of the literature, analysis, and integration with existing models. A conceptual model has an essential role in the scientific processes. Its purpose is to aggregate evidence, help in understanding phenomena, inform future studies and act as a reference operational index in practical settings. The study also creates avenues for future research and provides theoretical contributions.
