技术创新网络的拓扑结构与演化

Topology and Evolution of Technology Innovation Networks

Sergi Valverde, Ricard V. Solé, Mark A. Bedau, Norman H. Packard

摘要:

连接技术创新的关系网可以用专利引用来公平地描述。由此产生的专利引用网络提供了一个大规模的创新组织及其时间演变的图片。在这里,我们研究了美国专利商标局(USPTO)注册的专利的变更模式。我们表明,该网络所表现出的缩放行为是一致的优先连接机制,以及威布尔形老化长期。科学引文网络共享这样的连接内核,从而表明连接思想和设计及其演化的普遍机制。创新的进化理论的影响进行了讨论。

英文摘要:

The web of relations linking technological innovation can be fairly described in terms of patent citations. The resulting patent citation network provides a picture of the large-scale organization of innovations and its time evolution. Here we study the patterns of change of patents registered by the US Patent and Trademark Office (USPTO). We show that the scaling behavior exhibited by this network is consistent with a preferential attachment mechanism together with a Weibull-shaped aging term. Such attachment kernel is shared by scientific citation networks, thus indicating an universal type of mechanism linking ideas and designs and their evolution. The implications for evolutionary theory of innovation are discussed.
