Abstract: Sports data, as a vital category of data assets, faces a structural contradiction in its circulation and utilization: the separation of data control from value realization, which hinders data sharing and development. Existing models, such as data exchanges and alliance-based sharing, struggle to fundamentally resolve this issue due to a lack of endogenous trust mechanisms and effective rights protection systems. As an innovative model for data governance, the trusted data space is founded on the legal principle of “data sovereignty”. It operationalizes this principle through a fusion of legal rules and technological tools and thereby constructs an institutionalized cooperative network that guarantees “data remains within its domain, usable yet invisible.” This architecture exhibits a high degree of compatibility with the distinctive characteristics of sports data as an asset. Serving as infrastructure for sports data circulation and utilization, the trusted sports data space consists of a centralized trusted data space service platform and distributed access connectors. Leveraging three core capabilities, namely trusted management, resource interaction, and value co-creation, it facilitates a shift in sports data circulation from reliance on inter-stakeholder trust to dependence on system trust. To this end, measures should be taken across three dimensions—institutional supply, technological innovation, and governance coordination—to systematically advance the construction of the trusted sports data space and thereby establish a secure, efficient, and open new order for the circulation and utilization of sports data elements.
