新形勢下，短視頻通過提供沉浸式體驗，打破海峡兩岸政治、文化與平台的壁壘，在資訊交流、閩台融合發展等方面發揮了重要作用。本文基於互聯網模因理論，以閩台短視頻為研究對象，探究閩台短視頻模因的跨文化傳播策略。研究發現：閩台短視頻呈現零星式分佈狀態，暫未形成閩台區域性規模效應。究其原因，短視頻模因能否跨越兩岸壁壘，得以成功傳播的社會性根源，在於模因文化適應性的高低。本研究總結出閩台短視頻模因的跨文化適應性提升策略如下：就繼承屬性而言，可採取保留核心要素的冗餘策略；就傳輸模式而言，可採納指令型的基因模式；就傳播效應而言，可採用適應性的媒介豐富度策略。以期為閩台短視頻產業的創新融合發展政策落地提供參考意見。

Short videos break down the barriers of cross-strait politics, culture, and platforms by providing immersive experiences in the new situation, and play an important role in information exchange and Fujian -Taiwan integration development. Based on the theory of Internet memes, this paper takes Fujian-Taiwan short videos as the research object and explores the cross-cultural communication strategies of Fujian- Taiwan short video memes. It is found that Fujian-Taiwan short videos show sporadic distribution, and have not formed a regional scale effect of Fujian-Taiwan for the time being. We conducted an in-depth study on the reasons for this and finally concluded that the social root cause of the successful spread of short-video memes across the cross-strait barriers is the level of cultural fitness of the memes. In this study, we summarize the following strategies to enhance the cross-cultural fitness of Fujian-Taiwan short-video memes: for inheritance attributes, the redundancy strategy of retaining the core elements can be adopted; for transmission modes, the directive gene mode can be adopted; for dissemination effects, the adaptive media richness strategy can be adopted, so as to provide suggestions for the implementation of the policy on the innovative and integrated development of the short-video industry in Fujian-Taiwan.
