Digital platform ecosystems are becoming emerging business infrastructures， and due to power and information asymmetries， complementors within the system face new types of paradox relationships. Existing studies are still insufficient in understanding the complexity of multilateral relationships and the law of strategic power variability of complementors in digital platforms， and have not yet formed a systematic knowledge of paradox relationships management of complementors. Based on the visual analysis of relevant literature at home and abroad， it traced the theoretical origin of the formation of the paradoxical relationship of complementarities， and systematically sorted out the three sets of paradox relationships of ‘complementarity and dependence’，‘competition and cooperation’， and ‘legitimacy and uniqueness’ faced by complementors in the ecosystem of digital platforms. It further explored the influencing factors， management strategies， performance and outcomes of the paradox relationships， aiming to build an integrated research framework for the management of the paradox relationships of complementors in the digital platform ecosystem， and anticipate future research directions. The micro-level analysis of complementors’ entrepreneurial process from the perspective of paradox not only further explores the characteristics of the digital platform ecosystem context and integrates the existing research on complementors’ entrepreneurship， but also is of great significance in expanding the scope of application of paradox and promoting the development of paradox theory in the new competitive environment.
