本研究发现，大陆二次元御宅族群体内部存在以“世代”为划分的子群体。根据其主要接触媒介的不同可以区分为：电视时代的“80后”二次元御宅族、融合媒体时代的“90后”二次元御宅族以及新媒体时代的“00后”二次元御宅族。时代背景的不同造就了他们各自不同的二次元内容偏好和寻找同好的方式。本文将受访者对自我身份的确认与社交媒体上的身份构建交叉分析发现，不同世代在二次元身份的构建中存在着显著的差异。“80后”二次元御宅族表现为一致性的三次元身份。他们大多已经步入职场，二次元已经纯粹成为了他们的一个兴趣爱好。“90后”二次元御宅族表现为二次元身份的“隐匿”。他们之中的一部分人虽然在社交媒体上表现出的为三次元身份，然而其自我身份确认时却认为自己偏二次元。“90后”二次元御宅族更倾向于享受一个人的二次元世界，而鲜少通过“混圈”来确认自己的身份。“00后”二次元御宅族表现为勇敢呈现自己的二次元身份。他们之中的大多数乐于在社交媒体上与朋友分享自己的二次元爱好。此外，通过引入第三方观察者，本研究将被访者的自我身份确认与第三方观察者通过社交媒体表现对其的身份判断相结合，探讨其异同。研究发现，不同世代在这一结果上也有显著差异。“80后”二次元御宅族表现为一致性的三次元身份。随着“兴趣减退”、“身份退出”等等因素，他们已经逐渐从二次元世界走向了三次元世界。“90后”二次元御宅族表现为“封存的爱好与隐匿的身份”。虽然其自我身份确认中，偏二次元的身份居多，然而第三方观察者却认为她们为三次元群体。这与部分“90后”二次元御宅族在社交媒体上有意地构建自己的三次元身份息息相关。“00后”二次元御宅族则在社交媒体上表现出比前两个世代更偏向二次元群体的身份。

This paper will focus on otaku people, trying to figure out how they become 2-D lovers. Besides, this paper will systematically compartmentalize two dimension otaku people by generation and study the difference identity of 2-D lovers. With the methods of participant observation, in-depth interviews and questionnaire, the paper studies the construction of self-identity and social identity of 2-D lovers from different generations.The study found that there is generation diversity among 2-D lovers. We could divide them by the way of media contact. Post-80s 2-D lovers grow up in TV age, while post-90s 2-D lovers grow up in the era of media convergence. Post-00s 2-D lovers are used to the new media environment. Because the backgrounds of the times are various, different generation of 2-D lovers had distinct content preference and the way of socializing with the like-minded.This paper showed that there are some significant differences among the identity construction of various generations of 2-D lovers. Most people of post-80s 2-D lovers regard themselves as people who live in the real world. Since most post-80s 2-D lovers came into the workplace, animation became one of their hobbies. Although some post-90s 2-D lovers consider themselves as 2-D loves, they perform the identity of people in real world. Since they enjoy watching animation alone, there is no need for them to socialize with the like-minded to construct their identities. Post-00s 2-D lovers are more eager to share something about animation on social media.Besides, through third-party observers, the study will discuss the difference between self-identity and social identity of 2-D lovers. Post-80s 2-D lovers are similar in the construction of self-identity and social identity, while post-90s 2-D lovers are various. Post-90s 2-D lovers construct their identities intentionally could explain this difference. Post-00s 2-D lovers give more clear shape of their identities.
