Under the framework of layered data ownership, granting too much power to data controllers may further monopolize data by super digital platforms, while simply empowering data users may hinder the realization of data circulation and utilization. The response to data monopolies should be structured around the framework of production and circulation, with a focus on separately allocating data control rights and data utilization rights to balance the dual objectives of orderly data circulation and efficiency. In the data production phase, data controllers should be required to open access to essential data. The assessment of competitive harm caused by refusing to open essential data should focus on three dimensions: horizontal foreclosure, vertical foreclosure, and innovation blockage. This should involve a comprehensive evaluation of the legitimacy of two counterarguments: personal information and privacy protection as a competition dimension, and the incentives of innovation and investment as the sources of dynamic efficiency. In the data circulation phase, a“resource-collection-product”holistic approach should be adopted, with the legal personhood of data established, granting data sets a legal personality to construct a data legal entity system. This would promote competition in digital markets and improve consumer welfare. When mandating access to essential data and constructing a data legal entity system, careful conditions for use must be set up to avoid negative effects caused by over-application of the rules or system. |
