【摘要】 运用网络科学理论解析科研合作网络的结构特征,借以阐明科研主体的合作模式和行为机制,是当前科研合作关系研究的重要方向。基于复杂网络多尺度理论,研究构建了科研合作模式自宏观、中观到微观的多尺度分析方法,包括全局、模块和模体基本概念、一般方法及科研涵义;进而运用于实际复杂网络领域科学家合作网络中,有效揭示了不同尺度的合作模式和行为机制。研究提供了科研合作模式系统监测、分析和管理的层次化思路和方法。更多还原

【Abstract】 By applying the network theory,the identification of scientific collaboration network structures can help to understand the collaboration patterns and behavior mechanisms among scientific individuals. Based on the complex network multi-scale paradigm,the multi-scale network methods,i. e.,marco-,meso-,and micro-scale concepts,algorithms and applications were explored for analyzing the global,module,and motif structure of the scientific collaboration networks,respectively. Then,the multi-scale network methods were applied to investigate the multi-scale network collaboration patterns and behavior mechanisms of the scientist’collaboration network in the field of complex network research. It was revealed that: 1) at the marco-scale,the scientists’ collaboration network exhibits small-world and scale-free characteristics; 2) at the meso-scale,the network has a significant modular structure in which scientists’ collaboration relationships are more intimate and frequent,and 3)at the micro-scale,the network contains several specific motif collaboration patterns. Furthermore,the implications for the multi-scale governance and control strategy were discussed based on the multi-scale network structures and behavioral mechanisms.The research can provide hierarchical ideas and methods for detecting,analyzing and managing the collaboration patterns in complex scientific collaboration systems.更多还原
