Abstract: 【Purpose/significance】The growth of AIGC has significantly increased work productivity and transformed information cre‑ ation, but it has also relatively lowered the threshold to generating misinformation, obscured accountability, and heightened the diffi‑ culty in identification for managing misinformation. Combining the advantages of AIGC technology to combat misinformation, effective governance of misinformation can be achieved.【Method/process】This research begins with the novel ways of misinformation genera‑ tion at AIGC background, deeply explores the associated challenges in legal accountability, national governance, and technology as‑ pects. It also analyzes the new opportunities brought about by AIGC technological advancements for managing misinformation, ulti‑ mately proposing strategies for governance in the era of AIGC.【Result/conclusion】In terms of legal accountability, establish a gover‑ nance framework featuring a central core plus diverse collaboration. At the level of national governance, refine the legal and regulatory system, and balance the development relationship between artificial intelligence and national information security. Technically, miti‑ gate the impact of "illusions", enhance the security of AIGC technology, and construct large-scale models for specialized fields.【Inno‑ vation/limitation】Considering the effectiveness of AIGC technology in combating misinformation from multiple perspectives such as legal accountability, national governance, and technology, future research will consider introducing a wider range of data sources for in‑ stance verification.
