弹幕视频网站是以动画受众为主要群体的社交平台。根据准社会交往的理论框架，本研究通过内容分析法对受众在“哔哩哔哩”弹幕视频网站上的弹幕评论进行分析，以个案的形式来讨论日本动画对受众的影响及受众对动画角色的准社会交往表达。发现在“英雄—反派”为故事叙述结构下的日本动画片中，受众对不同类型角色的态度倾向存在显著差异，弹幕长度会因角色类型的不同而存在显著差异，态度倾向越积极弹幕评论长度越长，准社会表达类型与弹幕评论长度显著相关。本研究不仅对即时状态下的准社会交往测量进行了尝试，同时也为准社会交往及准社会关系的线性发展观点提供了佐证。除此之外，本研究尝试用工具变量的方法讨论了受众互动对受众表达的影响，并为未来的研究提供了可供发展的方向。

Danmu video sharing sites are most popular social platforms for animations audience. This study traces audiences reactions to Japanese animation personas through the theoretical framework of parasocial interaction. A thematic analysis using content analysis of 293 overlaid comments on Bilibili.tv is conducted. Results indicate that audiences’ attitude tendency and length of comments have significant difference between types of personas in Hero-Villain Japanese animation. Results also indicate a positive relationship between attitude tendency of personas and length of comments and significant correlation between parasocial interaction expression types and length of comments. This study measures the immediate-PSI and its findings support the view of liner progression of parasocial interaction and parasocial relationships. In addition, this study testes the effect of audience interaction on audience expressions by instrumental variable method and advises some directions for further studies.
