In 2021, the State Internet Information Office and other departments issued the Regulations on the Administration of Algorithmic Recommendation of Internet Information, which requires providers of algorithmic recommendation services with the ability to mobilise public opinion or social mobilisation to file a record in accordance with the law. This system aims to innovate the regulatory model, realise ‘agile governance’, and balance algorithmic safety and innovation. However, the legal attributes of algorithm filing are controversial from an administrative filing perspective, hindering the effective implementation of the system. At the same time, the unclear content boundary and the lack of information disclosure mechanism have also raised questions. To cope with these challenges, the administrative factual attributes of algorithmic filing need to be clarified, and the content boundary definition and information disclosure mechanism need to be standardised and improved. Thus, the algorithmic filing system can maximise its role in enhancing the effectiveness of algorithmic regulation, controlling algorithmic risks, safeguarding citizens' rights and interests, and protecting the public interest, so as to promote the goodness of science and technology, and to ensure the harmonious coexistence of technological development and social well-being.
