Abstract: As a newly established algorithm governance system in the digital era, the filing of generative artificial intelligence algorithms embodies the governance principle of "combining an effective market with a proactive government". It plays a significant role in the collection and disclosure of algorithm information and in promoting corporate self-governance and compliance. An examination of the current status of China's algorithm filing system reveals that it faces issues such as insufficient performance of administrative filing duties, the need for improvement in regulatory rules for algorithm filing, and the absence of supporting systems. Based on the nature, function, and guiding principles of algorithm filing, the development direction of generative artificial intelligence algorithm filing is clarified: Firstly, the obligation of algorithm filing authorities to receive materials and conduct procedural reviews should be confirmed, the algorithm filing reception process should be improved, the matters for supplementary notification in algorithm filing should be clarified, the classification review standards for algorithm filing should be enhanced, and the legality control of algorithm filing should be strengthened. Secondly, the algorithm filing period should be flexibly set, and multiple regulatory measures such as non-site inspections, "dual randomization and public disclosure" supervision, and credit risk classification and regulation should be adopted to form a regulatory synergy for algorithm filing and ensure its rational construction. Finally, an information sharing mechanism for algorithm filing should be established to promote the sharing of algorithm filing information resources among different institutions and departments, a systematic and scientific credit classification and evaluation system should be built, a credit-oriented notification and commitment system should be implemented, and a trust bridge between government agencies and algorithm filing entities should be established to achieve the rule of law in algorithm filing operations.
