In the era where the digital economy profoundly reshapes cultural industry chains, the exclusive copyright licensing system faces dual challenges of value adaptation and functional transformation. As a private rights instrument for digital platforms to shape business models, exclusive copyright licensing inherently enhances transactional efficiency and security. However,its technology-empowered nature—amplified by algorithmic recommendations, blockchain-based evidence preservation, and smart contracts—has transcended the traditional framework of copyright law. This has triggered triple negative externalities in copyright markets: resource-blocking competition, distorted allocation of copyright resources and diminished consumer welfare, alongside potential monopolistic risks that invite policy rejection. Nevertheless, copyright competition among digital platforms exhibits distinct content-driven and evolving characteristics. A rigid one-size-fits-all regulatory approach risks undermining the inherent advantages of licensing mechanisms in transactional efficiency and security, leading to weakened governance efficacy and obscured institutional strengths. Analyzing and resolving governance issues in digital platform copyright competition through licensing mechanism innovation necessitates a three-dimensional analytical framework of rights allocation,competition order,and institutional innovation, which aligns with the commercial logic of the digital economy. Firstly, digital platform copyright competition reflects a novel market paradigm where licensing mechanisms constitute competitive advantages, with monopolistic risks arising from the alienation of copyright exclusivity rather than traditional market scale effects. Secondly, the mechanical integration of administrative intervention and antitrust regulation has caused misalignment in legal evaluation systems, necessitating a reorientation of licensing functions within competition law. Thirdly, both the EU’s Digital Markets Act (DMA) and China’s Anti-Monopoly Law signal a shift toward procedural governance paradigms, demanding a dual-track system combining dynamic restraints and innovative remedies. To this end, fostering innovative and diversified reforms in copyright licensing models can synergize the private law values and competition law functions of licensing mechanisms, balancing creator incentives with dissemination efficiency while cultivating endogenous fair competition mechanisms. Firstly, establish a tiered-trigger dynamic restraint mechanism, deploying substantive copyright share monitoring models and scatter-diagram analyses of licensing durations to enable intelligent early warnings for threshold breaches. Secondly, introduce a competitive collective management model, conditionally granting digital platforms limited collective management authority under a competition declaration, differentiated fee, and blockchain revenue distribution regime. Finally, design a dual remedial toolkit comprising compulsory sublicensing and licensing right prohibitions to establish a gradated legal governance framework. In conclusion, the innovation of copyright licensing mechanisms aims to activate their behavioral remedy function in governing digital platform copyright competition, thereby advancing the sustainable optimization of digital copyright ecosystems and high-caliber development of copyright industries.
