This study proposes the construction of a three-dimensional dynamic evaluation model for academic journal impact, which establishes indicators across three dimensions—academic, dissemination, and knowledge services—and is empowered by artificial intelligence. It explores the direction of applying AIGC technology to facilitate the digital and intelligent transformation of academic journal evaluation in the context of media convergence, aiming to provide decision-making support for the paradigm shift toward a more comprehensive, intelligent, and dynamic approach to academic journal evaluation.
