摘　　要：当前对于社交网络“标准偶像”现象和机理的研究,仍缺乏足够重视、专门实证探讨和理论自觉。明确提出“标准偶像”的理论概念,并进行其机理实证分析。采用潜在语义分析(LSA)对微博用户的文本数据进行挖掘,结合统计检验和路径分析考察标准偶像的作用。社交网络内容生产中,高粉丝数、高流量、高咖位的用户,其个体的内容整体不是趋向丰富性、垂直细分和特立独行的差异化,而是趋向越来越重复、趋似和标准化。微博用户的粉丝数越高,则其趋同于标准用户的程度相应越高,用户粉丝数和内容之间的关系越来越闭合,促进高粉阶层的异质性不断被削磨,同一化标准化程度不断增加,表现出“标准偶像”的现象、效应及其社会文化逻辑。微博中的“标准偶像”及其传播后果,蕴含着从“大众偶像的胜利”到“标准偶像的胜利”、从多样话语崛起到封闭圈层和“社会窄化”的转向。For the research on the phenomenon and mechanism of“standard idol”in social network,there is still a lack of enough attention,special empirical discussion and theoretical consciousness.This paper puts forward the theoretical concept of“standard idol”and makes an empirical analysis of its mechanism.Latent semantic analysis(LSA)was used to mine the text data of microblog users,and the action path of standard idols was investigated by statistical test and path analysis.In the content production of social network,the content of the users with a lot of fans and high rank is not rich,vertically segmented and differentiated,but tends to be more and more repetitive,similar and standardized.For these users,the higher the number of fans they have,the higher the degree of their convergence with the standard users is,and the relationship between the number of fans and the content is more and more closed,leading to the fact that the heterogeneity of the class with a high number of fans is constantly reduced and the degree of identity and standardization is increasing.This shows the phenomenon,effect and social and cultural logic of“standard idol”.The standard idols in microblogs and their communication consequences imply a turn from“the victory of popular idols”to“the victory of standard idols”,from the rise of diverse discourse to the closed circle and“social narrowing”.
