媒介依赖视角的微博情感表达研究—“杭州保姆纵火案”事件为例

Research on Microblog Emotional Expression Based on Media System Dependence Perspective—Taking “Hangzhou Nanny Arson” as an Example

摘要: 微博营造的虚拟社区和真实生活交织在一起，尽管有大量有关微博研究的文献，但通过媒介依赖(MSD)理论，研究微博情感表达的研究很少，而目标受众会与微博传播形成双向作用的依存关系。因此，本文根据媒介依赖理论，以2017年关注度很高的网络舆情事件“杭州保姆纵火案”事件为例，从性别、年龄、发文长度和事件进展四方面对微博文本进行情感分析，探索用户情感表达的特征。研究结果表明：1) 微博中的情感表达与性别、年龄、发文长度和事件进展显著相关；2) 微博用户主要的三类情感表达，分别为：关注、悲伤和希冀；3) 在性别方面，女性相对更加感性；4) 在年龄方面，尤其是90后的微博用户有更强烈的情感表达方式；5) 在事件进展阶段方面，在事件进展的后期，情感表达更加趋于理性。研究结果对于应用媒介依赖理论探索社交媒体中情感表达特征，进行网络舆情管理有着启示意义。

Abstract: The virtual community created by Microblog is intertwined with real life. Despite a large amount of literature on Microblog research existing, there are few studies on Microblog emotions through media system dependence (MSD) theory. However, the target audience will form a two-way dependency relationship with Microblog. Therefore, based on the media system dependence theory, this paper takes the high-profile online public opinion event “Hangzhou Nanny Arson” as an example to analyze the comments from four aspects: gender, age, length of writing and event progress. The results show that: 1) The emotional expression in Microblog is significantly correlated with gender, age, length of writing and event progress; 2) The main three types of emotional expression are attention, sadness and hope; 3) In terms of gender, women are relatively more emotional; 4) In terms of age, especially those who were born after 90s, they have stronger emotional expression; 5) In the stage of event progress, emotional expression is growing with the development of event. The research results have implications for the application of media dependence theory to explore the emotional expression characteristics in social media and to manage online public opinion.
