在这篇文章中，我们从社会影响力的正式理论中得出有关社会地位的含义。形式理论描述了在一群具有异质初始意见的行动者中，人际影响网络如何进入行动者固定意见的形成。我们得到了以下关于结构等价的一种特殊形式的结论。如果行动者在人际影响网络中的结构是等价的，那么他们最初观点的任何差异都会被社会影响过程所减少，如果行动者的社会地位是相同的，也就是说，如果他们有相同的最初观点，并且在影响网络中的结构是等价的，那么他们在平衡时有相同的观点。如果行动者在人际影响网络中的结构不等同，那么社会影响过程并不一定会减少最初意见的差异。我们扩展我们的分析，考虑自守等价。
In this article we derive implications about social positions from a formal theory of social influence. The formal theory describes how, in a group of actors with heterogeneous initial opinions, a network of interpersonal influences enters into the formation of actors' settled opinions. We derive the following conclusions about a special form of structural equivalence. If actors are structurally equivalent in the network of interpersonal influences, then any dissimilarity of their initial opinions is reduced by the social influence process, If the social positions of actors are identical, i.e. if they have identical initial opinions and are structurally equivalent in the influence network, then they have identical opinions at equilibrium. If actors are not structurally equivalent in the network of interpersonal influences, then the social influence process does not necessarily reduce dissimilarities of initial opinions. We extend our analysis to consider automorphic equivalence.
