The issue of the discourse power is closely related to the realization and maintenance of national interests, and is an important symbol of national soft power. Global governance is global multilateral governance with the participation of multiple subjects, and it is a typical collective action. Due to the characteristics of collectivism and public choice in global governance itself, soft power, with the discourse power as the main cultural symbol, is now included in the important goals of competition among nations. For a long time, some western countries have always dominated the global political landscape due to their accumulated discourse power advantages. How to confront the strong encirclement and suppression of western discourse hegemony, how to enhance the dissemination of China's voice in the international community, and how to show the world a more three-dimensional and real China are major problems that China urgently needs to solve. Since the 18th National Congress of the Communist Party of China, the comprehensive national strength and international status of China have been significantly improved. Correspondingly, both China's voice and stories on the international stage have also received more attention, and China's discourse power has achieved new breakthroughs. However, none of this means that the current status of China's discourse power has been matched with the comprehensive national strength. There is no denying the fact that, compared with western countries, China's discourse power is still in a weak position. In order to win the "battle for the promotion of China's discourse power", based on the perspective of comparison and evaluation of discourse power, we should consider the connotation and logical relationship between global governance and China's discourse power from the perspectives of inheritance and continuation, international and domestic, so as to provide a theoretical basis and endogenous power for the research on China's discourse power. At present, China still faces many problems and challenges in disseminating Chinese voices, telling Chinese stories and providing Chinese solutions. The problems of "being scolded" and "being speechless" still exist, mainly including that China's discourse is suppressed by western discourse hegemony, anti-Marxist social ideology still exists, and that discourses slandering the socialist system are endless, etc. In response to these problems, accelerating the discourse power that matches China's comprehensive national strength has become a top priority from the perspective of global governance. Looking forward to the future, in the face of the risks and challenges, in order to allow other countries to accurately recognize the socialist system with Chinese characteristics, we should speak out on important occasions at home and abroad, and realize the transformation of China's role in global governance. Firstly, we should learn from experience and wisdom from China's governance concepts, institutional advantages, capabilities and practices so as to explore the ways of improving discourse power. Secondly, we should accurately grasp the general trend of development at home and abroad, and insist on transforming China's governance practice into discourse power. Thirdly, we should transform Chinese governance advantages into discourse power advantages. Fourthly, we should transform Chinese institutional confidence into discourse confidence. Lastly, we should transform our governance vision into world recognition. Thus, we will fully demonstrate China's governance achievements, and confidently participate in shaping global governance.
