Supply chain service platforms (SCSP) are playing an increasingly crucial role in improving the competitiveness of organizations in the digital economy. Little, however, is known about the critical factors to the adoption of SCSP in organizations for improving their performance. Drawing upon three domain theories in technology adoption in organizations including the technology-organization-environment framework, the innovation diffusion theory, and the interorganizational relationship theory, this study proposes and validates a research model for better understanding the critical factors to the adoption of SCSP using the survey data from 228 Chinese catering organizations. The study shows that organizational resources and external pressures have a significant direct impact on SCSP adoption in organizations. It reveals that perceived platform value fully mediates the effect of external pressures and partially mediates the effect of organizational resources on SCSP adoption. Furthermore, the study finds out that there is a significant positive association between SCSP adoption and organizational performance. This study contributes to better understanding of SCSP adoption in organizations in their active pursuit of sustainable performance.
