行动者网络结构熵的表征与测度

Description and Measurement of Actor-network Structure Entropy

为了分析行动者网络结构对网络内行动者合作关系建构的重要性,该文在三种网络结构熵模型的研究基础上,提出了一种点、边结合的行动者网络结构熵分析方法。通过定义行动者网络中行动者的点差异性和行动者间关系的边差异性,分析得到了星型网络、邻近网络和雁型网络等三种典型行动者网络的结构熵分析模型。运用MATLAB软件进行仿真试验。分析了不同网络结构下网络增长率对网络结构熵的影响过程,得到了网络结构和行动者间关系的作用规律。该文研究结果有利于改进对行动者网络的结构设计和诊断。

To analyze the effect of actor-network structures on members＇ cooperation, an approach integrating nodes and edges of networks based on the study of three types of network entropy models is proposed. By defining the nodes＇ differences and the edges＇ differences related to members＇ relationship of the actors in actor-networks,the network structure entropy models are obtained for three typical actor-networks like star network, neighbor coupling network and flying geese network. The effect of the increase of nodes and edges on network structure is simulated by MATLAB, meanwhile the influence of network on members and their relationship is achieved. This work contributes to improve the design and diagnoses of actor-network structures.
