Jingyou behavior is proposed on the basis of summarizing the development of human history and management practice of organization, which is a universal behavior mode. In order to better understand the regularity of Jingyou behavior and make the theory foundation for application, a systematic study on behavior mechanism of Jingyou is introduced from the behavior subjects’ perspective: i) the structure and relationship of Jingyou is illustrated with literature research method; ii) based on the related knowledge of evolution, social psychology and evolutionary epistemology, the connotation, phenotypes and evolution mechanism of the core of Jingyou are researched with metaphor research method; iii) according to the evolution path of “cognitivebeliefsintentionbehavior”, the complete behavior mechanism of Jingyou is given. This article adds new research contents to behavior science theory and makes a foundation for Jingyou theory’s further integration, perfection and promotion.
