中文摘要：	随着网络普及率的逐年升高以及科普相关政策的出现，短视频平台已经逐渐由娱乐化向知识化转型，用户可以通过短视频平台更加快速的获取知识并进行知识交流，科普类短视频也成为了平台关注的重点内容，因此，本文选取科普类短视频作为研究对象，探究其知识交流效率及影响因素。 本文选取抖音平台内的科普话题作为研究对象，获取抖音平台科普话题内的视频数据。选取用户数、视频发布量为投入指标，互动指数、收藏量为产出指标，利用SBM模型计算在2019-2022年间各个科普话题的静态知识交流效率，同时利用非参数Kernel估计探究知识交流效率的动态变化。最后利用Tobit模型进行回归分析探究知识交流效率的影响因素，依据研究结果为科普短视频知识交流效率的提升和发展提出可行性建议。研究发现抖音平台内科普知识的交流效率呈现先升后降再稳定的趋势，规模效率值整体高于纯技术效率值；不同科普话题的知识交流效率水平不同；发布视频的时间、视频时长时长，创作者的作品数、粉丝量、关注量和获赞量对知识交流效率有显著影响。
英文摘要：	With the network penetration rate rising year by year and the emergence of science-related policies, the short video platform has gradually transformed from entertainment to knowledge, and users can acquire knowledge and communicate more quickly through the short video platform, and popular science short videos have also become a hot topic of concern, so this paper selects popular science short videos as the object of study to explore the efficiency of its knowledge exchange and the factors that influence it. This paper selects popular science topics on TikTok as the research object, and obtains the video data of popular science topics on TikTok. The number of users and video release volume are selected as input indexes, and the interaction index and collection volume are output indexes, and the SBM model is used to calculate the static knowledge exchange efficiency of each popular science topic during the period of 2019-2022, and at the same time, the non-parametric Kernel estimation is utilized to explore the dynamic changes of the knowledge exchange efficiency. Finally, the Tobit model is used to explore the influencing factors of knowledge exchange efficiency, and based on the results of the study, feasible suggestions are made for the enhancement and development of knowledge exchange efficiency of popular science short videos. It is found that the communication efficiency of popular science knowledge on TikTok shows a trend of rising, then falling and then stabilizing, and the scale efficiency value is higher than the pure technical efficiency value; the knowledge efficiency levels of different popular science topics are different; the time and duration of the released video, and the amount of the creator's work, the amount of fans, the amount of attention, and the amount of likes have a significant impact on the knowledge communication efficiency.
