沉迷於粉絲文化的人們往往自願投身於「粉絲後援會」中成為群體一員，並以集體為單位進行粉絲活動，而粉絲組織若達一定規模時，商業公司往往也會考量與之合作，進行兼具交換價值的生產活動。本文以深圳的「Runningman」粉絲團為例，試圖從社會勞動與網絡分析的角度，探討粉絲群體從形成到沒落的過程，以及從中分析商業公司介入（或與之合作）的可能條件。研究發現，一方面粉絲群體通過文本的自我再生產，加強成員對群體的認同，而這種文本的持續生產對於群體發展成為成熟的組織具有關鍵作用。另一方面，組織內部依連結關係的多寡而形成核心成員與普通成員，依專業分工的職掌而形成若干的功能次群體。核心成員與功能次群體的出現，除了標示著組織內部的結構已逐漸分層和複雜，也代表組織已達一定規模，能吸引商業公司與之合作。然而，資本的介入雖然能增強核心成員的領導力與次群體分工的專業性，卻也引發普通成員與核心成員之間的矛盾。最後，粉絲組織之所以沒落，根源於核心成員的離開、政策和節目人氣的影響，而粉絲的熱情大幅下降，會直接反映在文本生產和線上互動都隨之減少，而線上互動的減少也連帶影響線下的活動，形成「死群」現象。

People who are obsessed with fan culture often voluntarily join the “fan group” to become a member of the group and engage in fan activities collectively. When fan organizations reach a certain size, commercial companies often consider cooperating with them to conduct production activities with exchange value. This article takes the “Runningman” fan group in Shenzhen as an example, trying to explore the process of fan group formation to decline from the perspective of social labor and network analysis, and analyze the possible conditions for commercial companies to intervene (or cooperate with). The study found that, on the one hand, fan groups strengthen members’ identification with the group through the self-reproduction of texts, and the continuous production of such texts plays a key role in the development of the group into a mature organization. On the other hand, the core members and general members are formed within the organization based on the connection relationship, and several functional subgroups are formed based on the division of professional duties. The emergence of core members and functional subgroups not only indicates that the internal structure of the organization has gradually been layered and complicated, but also that the organization has reached a certain scale and can attract commercial companies to cooperate with it. However, although the involvement of capital can enhance the leadership of core members and the professionalism of sub-group division of labor, it also triggers conflicts between general members and core members. Finally, the reason for the decline of fan organizations is that due to the influence of core members leaving, policies and program popularity, fans’ enthusiasm has disappeared significantly. This is directly reflected in the decrease in text production and online interaction, and the decrease in online interaction also affects offline activities, forming the phenomenon of “dead group”.
