China put a filing number behind recommendation algorithms

The test

China's Cyberspace Administration, together with the Ministry of Industry and Information Technology, the Ministry of Public Security and the State Administration for Market Regulation, issued the Provisions on the Administration of Algorithm-Recommendation Services for Internet Information Services, dated 31 December 2021 and posted on the central government's policy portal on 4 January 2022, with the rules taking effect 1 March 2022. The provisions cover internet services using generative synthesis, personalized recommendation, ranking selection, search filtering and scheduling-decision algorithms, a definition broad enough to include short-video recommendation systems generally, though the text itself does not name individual companies or platforms.

What the evidence says

Article 24, as hosted on the Cyberspace Administration's own copy of the same notice, requires operators whose algorithms carry opinion-leading attributes or social mobilization capacity to file within ten working days of launch through an official filing system, submitting the provider's name, service type, application domain, algorithm category and a self-assessment report. Article 26 requires filed operators to display their registration number on the service itself. Article 16 separately requires providers to disclose, in prominent form, the basic principles, purposes and main operating mechanisms of their recommendation services. Both government pages carry the same legal text; neither names which specific platforms have filed, and this record does not assert that any named company has registered beyond what these documents state.

The sample and the variance

The provisions apply to algorithm operators serving users inside mainland China, not a global standard, and the filing requirement is triggered by a stated characteristic, opinion-leading attributes or social mobilization capacity, that the text itself does not reduce to a numeric threshold such as a user count. The two government sources establish what the rule requires and when it took effect; they are not a disclosure of which companies complied, how many algorithms have been filed, or how the filing system evaluates a self-assessment report once submitted.

What to try next

As an editorial framing beyond the text itself, an observer tracking platform accountability in China can treat this filing requirement as a disclosure mechanism aimed at regulators rather than the public at large, since Article 16's user-facing disclosure duty and Article 24's regulator-facing filing duty are separate obligations described in the same document. Distinguishing a platform's public-facing algorithm description from what it may have filed under Article 24 avoids conflating two different audiences for two different disclosures.

• Does a claim about China's algorithm registry specify Article 24's filing duty or Article 16's public disclosure duty?
• Is a cited figure about registered algorithms sourced to a government filing-system record, or assumed from the provisions' scope alone?
• Has the operative threshold, opinion-leading attributes or social mobilization capacity, been applied to the platform in question by a named regulatory action?

The provisions are a real, dated regulatory requirement with a specific effective date and specific disclosure articles; what they do not provide, in the text alone, is a public accounting of which platforms have filed or what those filings contain.
