传播新技术划定和塑造青少年的同辈关系，深刻影响该群体的社会化过程。采用“社会网络
分析”（SNA）范式，本研究考察青少年基于“社会交互式传播技术”（SITs）的同辈关系网对
现实社会中同辈友情关系的可能影响。基于关系数据的分析表明，SITs使用对青少年的现实交往
具有增进作用，提高了友情关系网络结构的丰富性，但也呈现出与现实友情网中不同的权力资源
分布状况。同时，受访青少年的现实友情网络指标在相当程度上决定了SITs关系网的相应指标。
本文揭示了社会网络分析范式对新媒体社会效果研究的方法论价值，也体现出通过引入新的解释
概念以比较与融合不同的理论假设，以及开掘新的理论拓展方向的潜能。

New communication technologies will help to define and shape teenagers’ relationships with their
peers. It is also a social procedure which will deeply impose influence on them. This research focus
on how the peer social network with SITs might affect their friendships. Our data disclosed that SITs
promoted teenagers’ social interaction and enriched their social network. Nonetheless, there is different
power resource distribution compared with their real social networks. At the same time, the real network
index of teenagers being investigated mostly decides the associated SITs network index. We found out
the methodological value of SNA paradigm in effect research of new media. And we also explored thepotentiality of developing new theory with comparison of different hypothesis.
