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系统模式监测、分析和管理的层次化思路和方法。

The identification of the scientific collaboration network structure using network theory can help to understand the collaboration patterns and behavior mechanisms among scientific individuals. Applying with complex network multi-scale paradigm, the multi-scale network methods, i.e., marco-, mesco-, and micro-scale concepts, algorithms and applications for analyzing the global, module, and motif structure of the scientific collaboration networks were explored. Furthermore, these methods were effectively applied to reveal the multi-scale nework collaboratin patterns and behavior mechanisms of the real scientists’ collaboration network in the field of complex network research. The research may provide hierarchical ideas and methods for detecting, analyzing and managing the collaboration patterns and behavior mechanisms in complex scientific collaboration systems.
