In recent years, Chinese science fiction works have actively appeared on the international stage through platforms such as the Hugo Awards, the World Science Fiction Convention, and the China Science Fiction Convention, thus becoming a significant part of China's cultural discourse power. However, existing research has predominantly focused on developed markets in Europe and North America, with limited systematic empirical studies on emerging regions such as Latin America and Africa. This paper focuses on seven major emerging markets in Latin America and Africa, conducting an empirical analysis of the dissemination status and optimization strategies of Chinese science fiction, based on data from international communication big data platforms and Amazon. The study finds that Chinese science fiction has achieved "initial acceptance" in these markets and is gradually transitioning towards "deep integration." However, challenges remain in ensuring the sustainability of discourse dissemination, improving the precision of translation and cultural adaptation, and strengthening the integrity of industrial collaboration. Building on these findings, this study advances a three-dimensional pathway for optimizing the international dissemination of Chinese science fiction: strengthening data-driven market intelligence and localization strategies, enhancing cross-cultural translation and adaptation through intelligent technologies, and constructing a digitally empowered IP communication ecosystem. Such efforts are expected to promote the transformation of Chinese science fiction from outward dissemination to deeper cultural integration within overseas markets, offering practical insights for the development of a future-oriented international communication framework.
