士兵非正式群体是军队基层单位中的“微型社会磁场”,是一种对军事组织的整个水平有重要影响的小群体现象。本文以进入现役一至五年的男性青年为基本对象,通过多次实地调查(复合样本规模N=2180),就士兵非正式群体中核心角色的实际发育状态、士兵对这种重要互动对象的基本角色期待以及现实中的角色特征等问题,对这类小群体的核心成分进行了多层面的实证性研究。 The informal ranks of soldiers are the “micro-social magnetic field” in the grassroots units of the military and are a small group phenomenon that has an important influence on the entire level of military organizations. In this paper, we take the male youth entering the active service for one to five years as the basic object. Through several field surveys (compound sample size N = 2180), the actual development status of the core role in the informal group of soldiers is analyzed. The soldiers’ basic understanding of this important interactive object The expectation of the role and the character of the reality, and so on. The core components of these small groups have been studied empirically in many aspects.
