中文摘要：

技术创新网络的复杂性决定了研究其演化需要从多个关系层面同时观察。本文基于动态网络分析方法，设计了技术创新网络演化的测度体系，以中药制剂技术领域专利为例构建具有多重属性节点的技术创新网络，并进行了实证研究。结果表明技术创新网络的重要节点和连接随时间不断更迭。文章从整体网络拓扑特性和节点位置上对技术创新网络演化机制进行系统分析、对网络中潜在的重要关系和变化进行识别，最终验证了动态网络分析法在刻画技术创新网络演化方面的有效性。

英文摘要：

The evolution of technological innovation network needs to be observed from multiple levels for its complexity. In this paper, the measuring system of technological innovation network is designed on dynamic network analysis, and then the technological innovation network with multiple attribute node is designed by the example of the patent in Chinese drugs pharmaceutics field, which is studied empirically. It indicates that the important nodes and links of the technological innovation network constantly change. In this paper, the mechanism of evolution of the technological innovation network is analyzed systematically from the network topology and the location of nodes. At the same time, the underlying important relationship and change in the network is recognized. In the end, it proves that dynamic network analysis can describe the evolution of technological innovation network effectively.
