The Change Agent: A Taxonomy in Relation to the Change Process
回顾了变革推动者一词从起源到当前行为科学文献中的用法，基于Lewin的社会变革三阶段范式构建了十类变革推动者的分类，并描述了每类的活动和特征。
The article begins with a historical review of the term change agent from its origin in Lippit, Watson, and Westley to current usage in behavioral science literature. More detailed descriptions are provided for research that has been conducted on change agents. Lewin's three-phase paradigm of social change is used to construct a taxonomy of ten categories of change agents involved. Activities and characteristics are proposed for each category, citing recent research efforts to substantiate them.
