随着移动互联网技术的飞速革新以及智能移动终端的大量普及，短视频作为一种新型信息传播媒介应运而生。人们生活节奏加快，碎片化的阅读习惯已经形成，在注意力稀缺的时代，短小精悍、信息密集、生动直观的短视频弥补了图文信息的不足，更加契合人们新的阅读习惯。短视频深刻影响着人们社交娱乐和获取资讯的方式，受到大众追捧。

本文以传播学经典理论“5W”模式为根本立足点，对资讯类移动短视频从传播者、传播对象、传播内容、传播渠道和传播效果五个要素进行全面分析，深入了解其传播特征。首先，从传播者来看，资讯类移动短视频普遍采用专业内容生产与用户内容生产相结合的PUGC模式进行创作，既能保证信息内容的准确性又能保证资讯发布的时效性；从传播对象来看，受众获取信息资讯的需求十分迫切并普遍具有强烈的社交意愿。其次，从传播内容来看，资讯类移动短视频有着独特的语法特征与叙事方式，其时长、解说、字幕、音乐、标题等要素都与传统新闻媒介存在巨大差异；它在选题上更加注重社会价值和社会影响力，内容的价值取向趋于中立又不避讳负面报道。另外，资讯类移动短视频的传播渠道不单单局限于自有平台，还广泛依托社交平台构建全网分发的传播矩阵。最后，其传播效果深刻而广泛，在受众的认知层面、心理和态度层面、行为层面都产生了潜移默化的影响。

不过，作为近几年才诞生的新兴传播方式，短视频媒介与资讯类内容在磨合过程中不可避免地暴露出很多缺陷。为了长久的良性发展，现阶段的资讯类移动短视频有一些问题亟待解决，例如部分资讯内容缺乏互动性，用户参与度低导致平台用户粘性较差；碎片化的叙事方式导致事实不清；情绪化的传播风格导致舆论失焦；平台变现模式有限，对原创内容的版权保护不足等。

基于对资讯类移动短视频领域的系统研究和对头部平台梨视频的个案分析，本文从平台、内容、商业三个方面提出了应对上述问题的发展策略：首先，平台应建立用户思维，通过不断优化升级互动机制来塑造用户参与感，打破信息茧房，满足用户的社交需求。其次，在内容方面要参透短视频“碎片化”的特性，充分利用其优势辅助整体认知，从而挖掘短视频内容在构建宏大主题上的价值；生产主体还应秉持对社会负责的态度，提高对内容质量的监管力度。最后，在商业变现模式上应注重打造品牌IP，积极拓展海外市场，从而形成完整的生态产业链并捍卫新闻自由。

With the rapid innovation of mobile technology and the popularization of smart mobile terminals, short video which is a new information communication medium emerges into place. As the pace of people's life is accelerating, habits of fragmented reading have been formed. In the era of scarce attention, short video makes up for the shortcomings of graphic information due to its conciseness, intensive information, and vividness, which is more suitable for the new reading habits. The short video has a profound impact on the way people entertain and get information, making it increasingly popular among the public.

Based on the classic "5W" model of communication theory, this paper makes a comprehensive analysis of the information mobile short video from the communicator, communication object, communication content, communication channel and communication effect, so as to have an in-depth understanding of its communication characteristics. First of all, from the perspective of communicators, information mobile short videos are generally created using the PUGC mode combining Professional Generated Content and User Generated Content, which ensures both the accuracy and the timeliness of information. Second, from the perspective of the communication object, the audience has an urgent need to acquire information and generally has a strong will of socializing. Third, from the perspective of communication content, information mobile short videos have unique grammatical features and narrative modes. Its length, commentary, subtitles, music, titles and other elements are very different from traditional news media. Besides, it pays more attention to the topics with social value and social influence, and the value orientation of the content tends to be neutral and does not avoid negative reports. Fourthly, the communication channel of information mobile short videos is not only limited to its own platform, but also widely relies on social platforms to build a network-wide distribution matrix. Finally, its communication effect is profound and extensive, which exerts a subtle influence on the audience's cognition, psychology, attitude and behavior.

However, as an emerging communication method that was born in recent years, many defects are inevitably exposed in the process of combination between short video media and information content. In order to achieve long-term healthy development, there are some problems that need to be solved urgently. For example, some information content lacks interactivity; low user participation leads to poor user viscosity on the platform; fragmented narrative methods lead to unclear facts; emotional communication style leads to public opinion out of focus; and the profit model of the platform is limited and the copyright protection of original content is insufficient.

Based on the systematic research in mobile informative short video and the case analysis of Pear Video, this paper proposes the development strategies to deal with the above problems from three aspects which are platform, content and business mode. Firstly, the platform should establish user thinking, through continuous optimization and upgrade the interaction mechanism to create user participation, break the information cocoons, and meet users' socializing needs. Furthermore, it is necessary to deeply understand the fragmented characteristics of short videos, and make full use of its advantages to gain more overall cognition, so as to further explore the value of short videos in expressing grand themes; it is also necessary to strengthen the supervision of content quality to be responsible to the society. Finally, to establish the business profit model, mobile informative short videos should focus on building brand IP and actively expand overseas markets to form a complete ecological industry chain and defend press freedom.
