As an important part of the realization of "cultural power", academic discourse power is an important measure of its comprehensive national strength and cultural soft power, and it is highly valued by all countries in the world. The "discourse power theory" and "cultural leadership theory" successively put forward by developed countries in Europe and America, as well as the Western cultural hegemony theory, have been leading the development of the world's discourse power. In recent years, there have been extensive discussions on topics such as "lack of academic discourse power", "construction of academic discourse system" and "strategies for enhancing academic discourse power". Academic discourse power is the key element in the construction of academic discourse system. As soft power, academic discourse power has an extremely far-reaching impact on social development and academic prosperity. Exploring the research status and enlightenment of international academic discourse power can help China build the theory, method and application system of scientific evaluation of academic discourse power. Therefore, this paper selects the relevant research results in the core collection database of Web of Science, conducts statistics and analysis on the country of international academic discourse power through Citespace, uses Vosviewer to analyze the hot topics of international academic discourse power literature, and then the bibliometric analysis method is used to comprehensively analyze and summarize the research progress of relevant research literature. The results show that the hot topics of international academic discourse research mainly focus on theoretical research on academic discourse and linguistics, cross-cultural, cross-language and interdisciplinary academic discourse research, the role of academic discourse in political discourse, identity recognition and socialization, and academic discourse evaluation and quantitative research. This paper comprehensively analyzes the impact of international academic discourse power on China's academic discourse power and its future development and proposes a realization path to improve China's academic discourse power. In practice, learning from domestic and foreign experience and theories can innovate the promotion mechanism of academic discourse power. Specifically, it includes:combining top-down national strategies with bottom-up promotion from all walks of life; constructing scientific and feasible classification and evaluation indicators for academic discourse power, and adopting differentiated policy support for academic discourse power in different fields; improving academic discourse content innovation, platform construction and dissemination efforts. In addition, in the era of big data and artificial intelligence, it is necessary to use its own strength to create a first-class all-media and multi-language academic communication platform, so that Chinese academic frontiers and academic discourse can be spread farther and wider on the international stage. Finally, academic masters can be managed and cultivated scientifically and be encouraged to participate in the setting of international academic issues.
