当代大学生出生在互联网迅速发展的时代，互联网渗透了他们生活的方方面面，构建了他们的社会生活和人际关系。已有研究发现，与现实友谊相比，网络友谊亲密度更高，质量较低，其中资本的转化及情绪的冲击使得过往研究者认为网络友谊是虚拟或真实的不同态度，却忽略了当代大学生网络友谊的实际经验。本研究通过资本理论和媒介化理论进行分析大学生的网络友谊建构过程，探索其特征及意义，进而完成对社会媒介化在网络友谊层面的认识。通过访谈16名00后大学生，获得当代大学生网络友谊的建构过程的访谈资料，发现大学生网络友谊建构过程经历了相识、相知和相惜三个阶段，且以不同的态度和方式对待发生在不同阶段的友谊结束危机。在当代大学生看来，通过网络建立起的长久友谊，是生活中真实经历的、无法割裂的体验，值得教育者正视和不断学习，来更好地提高受教育者的网络素养。

Contemporary college students were born in the era of rapid Internet development. The Internet has penetrated every aspect of their lives and rebuilt their social life and interpersonal relationships. Previous studies have shown that compared with offline friendship, online friendship has higher intimacy but lower quality. The transformation of capital and the impact of emotions have made previous researchers respectively believe that whether online friendship is virtual or real, but ignored the experience of college students' online friendships. Capital theory and mediatization theory were used to analyze their online friendships construction process explore the characteristics and the significance of their online friendships, and contribute to a better understanding of social medialization at the level of online friendships. Therefore, interviews with 16 post-00s college students were conducted, obtained the materials of the construction process, and found the three stages of the online friendships construction process: meet by chance, know each other well and appreciate mutually. Also, they have different attitudes and ways of dealing with breakups that occur at different stages. The results of this study indicate that for college students, the long-term friendships they have established online are inseparable experiences that they have experienced in real life, which is worthy of educators’ attention and continuous learning, to better improve digital literacy.
