本文首先介绍了社会网络的特性，提出了关系函数和网络关系对网络中信息和节点的影响。在这个基础上，对因特网的社会网络特性进行论述。本文认为因特网具有社会网络的所有特性，但也与之存在差异，并重点阐明了因特网对社会网络的三种影响：人际关系简单化、信息膨胀和创新加快。 This paper first introduces the characteristics of social networks, and proposes the relationship between the relationship functions and network information on the network nodes and the impact. On this basis, the social network characteristics of the Internet are discussed. This paper argues that the Internet possesses, but differs from, all of the features of social networks and focuses on three effects of the Internet on social networks: simplistic relationships, informational expansion, and accelerated innovation.
