ABSTRACT
Based on the patents authorized for inventions in the Chinese medicine industry from 2005 to 2016, a patent co-occurrence network is constructed using international patent classification (IPC) information; And based on the K-shell decomposition method to identify core technologies in the network, the technical structure, research hotspot, and the absorption of other technical topics in core areas of traditional Chinese medicine are analyzed. The absorption of innovation in different periods is further described to explore the development trend of the traditional Chinese medicine industry, technological growth points and the main areas of absorption of core technologies of traditional Chinese medicine, in order to provide references and suggestions for industry technological innovation of traditional Chinese medicine.
