Against the backdrop of global value chain restructuring and the transition to a digital civilization, cultural soft power has become a key indicator of a nation's comprehensive competitiveness. This study employs the theory of new quality productivity as a framework to explore the application of artificial intelligence (AI) technology in cultural communication and education, particularly its enabling role in the international dissemination of the “Three Sus” culture (referring to the literary works of Su Shi, Su Xun, and Su Zhe). By constructing a three-dimensional “technology-culture-language” integrated curriculum system and combining quantitative and qualitative research methods, the study validates the effectiveness of AI technology in enhancing cultural communication. The results demonstrate that the deep integration of AI significantly improves students’ cultural communication efficacy and learning outcomes, while also revealing challenges and areas for improvement in technology application. This research provides theoretical support and practical pathways for the digital transformation of cultural communication education.
