On December 25，2024，the Law of the People’s Republic of China on Popularization of Science and Technology underwent its first revision since its enactment 22 years ago. This revision introduced new regulations concerning the governance of disinformation and misinformation，providing a legal foundation for the collaborative governance of such information. Grounded in an analysis of the current challenges in combating disinformation and misinformation，this study examines how the revised Law of the People’s Republic of China on Popularization of Science and Technology shapes the framework for collaborative governance of disinformation and misinformation，and further explores implementation pathways for such governance under this framework. The study finds that the revised Law of the People’s Republic of China on Popularization of Science and Technology establishes a governance framework characterized by multi-stakeholder co-governance. It introduces a dual content review standard focusing on both scientific validity and legality and constructs a comprehensive governance system featuring“prevention-monitoring evaluation -disposal”，which provides solutions to the governance challenges of disinformation and misinformation in the digital intelligence era. In the future，it is necessary to establish a multi-dimensional and integrated safeguard system encompassing institutional frameworks，technological infrastructure，organizational and talent development，economic and resource allocation，as well as social and cultural dimensions to promote the effective implementation of relevant legal provisions.
