This study examines how relational mechanisms among key airport stakeholders, specifically airport operators, airlines, and ground handling firms, shape airport and firm performance. Drawing on stakeholder theory, airports are conceptualized as multi-actor service platforms in which performance emerges from interdependent coordination rather than isolated organizational activities. Prior research has primarily emphasized operational, structural, and technological determinants, with limited attention to the relational micro-foundations of coordination. In particular, the roles of inter-organizational voice and transparency remain underexplored in complex airport settings. Addressing this gap, the study investigates inter-organizational promotive and prohibitive voice behaviors as complementary coordination mechanisms through which inter-organizational actors propose improvements and raise concerns, and examines how transparency conditions their effectiveness. Using qualitative data from in-depth interviews with managerial representatives across the three inter-organizational actor group, the findings show that both forms of voice enhance airport- and firm-level performance by enabling collaborative problem-solving, continuous improvement, and early risk detection. Transparency further strengthens these effects by improving the clarity and usability of shared information, thereby increasing coordination effectiveness. By distinguishing between inter-organizational promotive and prohibitive voice and examining their interaction with transparency, this study advances stakeholder theory and operations management research by identifying relational micro-foundations of coordination in multi-actor systems. The findings show that performance variation in complex service platforms is better explained by how actors communicate and respond to one another than by structural arrangements alone. The study also offers actionable insights for managers seeking to improve coordination and performance through the design of voice and transparency mechanisms.

In today's dynamic business environment, leveraging innovative supply chain (SC) solutions is critical for increasing competitive advantage. While numerous studies have considered the potential of SC innovation (SCI) in the face of growing new problems and challenges, not much is known about the effect of suppliers' promotive voice behavior (PVB) in this process. This study extends the current research on SCI by investigating the underlying mechanisms by which firms exploit the suggestions and ideas they gain from SC interactions. Building on the relational view (RV) we develop hypotheses that identify the effect of suppliers' PVB as an important mediator in the relationship between incentives and SCI. Further, we suggest that incentives and two contextual factors (i.e., unlearning reputation and transparency) interact to predict SCI through suppliers' PVB. For the purpose of testing the proposed hypothesis a survey was administrated to managers involved in SC relationships. The analysis provides the evidence that suppliers' PVB has a positive influence on SCI. In addition, the association between incentives and SCI was empirically demonstrated to be mediated by suppliers' PVB. Furthermore, it was determined that incentive's effect on SCI through suppliers' PVB was conditional such that unlearning reputation's effect depended on transparency. In this regard, this study extends the discussion of factors that influence SCI and provides some theoretical and managerial contributions by examining the interplay between incentives, transparency, and unlearning reputation on the suppliers' PVB and SCI.
