【摘要】 媒介技术的发展制约和塑造着国家话语的传播模态及话语互动方式。新媒介为国家话语的国内外传播带来了更多新的可能性，但由此产生的“众声喧哗”语境与“蒲公英效应”也使国家话语的生产和传播面临着巨大挑战。在国家话语生产与传播的过程中，言说主体对话语事件的整合能力、对话语框架的建构能力、与言说对象的话语交互能力以及文本与语境的适配度是影响传播效果的重要因素。由此针对不同的话语事件建构适切的话语框架，重视话语主体的层次类型及话语交互的主体间性，以“再语境化”策略增强国家话语传播的语用效果，是提升国家话语新媒介传播效果的有效路径。更多还原

【Abstract】 The development of media technology constrains and shapes the modes of communication and interaction in national discourse. While new media has opened up new possibilities for the domestic and international dissemination of national discourse, it has also led to challenges, such as the “clamor” and “dandelion effect”. In the production and dissemination of national discourse, key factors influencing its effectiveness include the ability of the subject to integrate discourse events, construct discourse frameworks, engage with the target audience, and adapt the text to its specific context. Therefore, to enhance the effectiveness of national discourse communication in new media, it is crucial to construct appropriate discourse frameworks for different discourse events, consider the hierarchical types of discourse subjects and the inter-subjectivity of discourse interaction, and improve the pragmatic impact of communication through the strategy of “re-contextualization”.更多还原
