Despite the societal benefits multi-sector innovations provide, researchers' understanding of the stakeholder issues surrounding them is limited. This study utilizes an inductive, theory-building approach to identify the means through which firms introducing multi-sector innovations can actively shape relationships between public stakeholders in order to better ensure innovation success. Individual, organizational, structural, and attitudinal antecedents emerged from an analysis of published documents detailing multi-sector innovations over a 2-year span. These antecedents are integrated with existing literature to produce a conceptual model and accompanying propositions. Managerial and theoretical implications are discussed, and future research directions provided. © Taylor & Francis Group, LLC.
