Abstract: Under the great changes in the past century, emerging transnational technologies have been brought into the radius of American game against China. Scientific analysis of the narrative content of American science and technology in China can provide a mirror for American science and technology issues and American public opinion research on China. Based on the strategic narrative theory, this paper clarifies the strategic narrative of American science and technology to China in the topic of "Ban TikTok". It is found that the operational path of American strategic narrative of science and technology to China is divided into framing strategic scope, emphasizing strategic connection, intensifying strategic contradiction and solidifying strategic narrative, which embodies the narrative thinking that the United States links stereotypes and stigmatizes China's science and technology, forms a whole-subject narrative layout of "government-media-think tank", establishes narrative skills based on wedge strategy, and finally achieves the goal of suppressing rising countries by science and technology. The narrative of American science and technology strategy to China protects American international discourse right, but it is limited by the intermittent characteristics of American science and technology policy, the large-scale development of China's science and technology going to sea and the common conclusion of emerging global science and technology norms. The U.S. strategy of suppressing Chinese science and technology has been transferred to other China science and technology products. Therefore, the narrative suppression analysis of American science and technology to China should be transformed into relevant strategic industries, so as to help China science and technology to respond to the situation and follow the trend.

摘要： 百年大变局下，新兴跨国科技被纳入美国对华博弈半径。科学分析美国对华科技的叙事内容，能够为美国科技问题及美国涉华舆论研究提供镜鉴。文章基于战略叙事理论，厘清美国在“TikTok出售门”议题中的对华科技战略叙事。研究发现，美国对华科技战略叙事的操作路径分为框定战略范围、强调战略关联、激化战略矛盾和固化战略叙事，体现着美国勾连刻板印象污名化中国科技的叙事思维，形成了“政府-媒体-智库”的全主体叙事布局，立基于楔子战略的叙事技巧，最终达成守成国对崛起国的科技打压目标。美国对华科技战略叙事护持了美国国际话语权，而美国科技政策间断性特征、中国科技出海规模化发展和全球新兴科技规范的共通缔结皆对其形成了限制。美国对TikTok的打压战略，已迁移至其它中国科技产品。是以，就美国对华科技的叙事打压分析应转化到相关战略产业，助力中国科技出海的应势而动与顺势而为。
