The paper, based on the concept and the elements of human resource ecosystem (HR Ecosystem), studies the function and structure of HR Ecosystem, introduces the entropy theory to define the content of entropy of HR Ecosystem, constructs the corresponding distinctive model to distinguish the direction of the evolution of HR Ecosystem and the evolutionary entropy model, and applies the models to demonstrate the evolutionary rules of HR Ecosystem. The study shows that the entropy theory can be well applied to the analysis on HR Ecosystem and that it opens up a new field in the research of human resource management and provides a new effective technical method. 展开更多

As an ecosystem in geological history, palaeocommunity has the essence of thermodynamics. This paper introduces the concept of entropy into the study of the evolution of palaeo-community, and proposes four parameters to represent the structure feature of palaeo-community. This theory is used to calculate the evolution mode of branchipod community of Maokou formation in Liziya area, Huaying Moumtain, Sichuan. 展开更多
