专利视角下长三角中药产业创新网络演化分析

长三角中药产业一体化高质量发展上升到国家战略，针对长三角中药产业协同创新问题，运用协同创新理论，从社会网络角度分析创新网络的结构及特征演化。利用1987—2021年长三角中药合作专利数据，从4个时间阶段对创新网络进行测度。研究发现：(1)长三角中药产业创新网络规模不断扩大，知识交换能力较强但传递效率较低；(2)创新主体向多元化合作发展，创新合作网络初步建立并逐步复杂化和社区化。其中，南京一直扮演着“高重要性-高协调性”的角色。研究对合理配置长三角中药产业创新资源，依托资源核心型城市加强创新网络建设，加快长三角中医药一体化高质量发展具有重要意义。

Analysis on the Evolution of Innovation Network of Chinese Materia Medica Industry in the Yangtze River Delta from the Perspective of Patent

The high-quality development of the integration of Chinese materia medica industry in the Yangtze River Delta has been risen to the national strategy. As for the problem of collaborative innovation of Chinese materia medica industry in the Yangtze River Delta, the structure and characteristic evolution of the innovation network were analyzed from the perspective of social network with the theory of collaborative innovation. The innovation network was measured from four stages with the data of Chinese materia medica cooperation patent in the Yangtze River Delta from 1987 to 2021. The research found that the scale of the innovation network of Chinese materia medica industry in the Yangtze River Delta has been expanding, and the knowledge exchange capacity was strong while the transfer efficiency was low. Besides, the innovation subject was developing towards diversified cooperation, and the innovation cooperation network was initially established and gradually becoming complication and communitization, among which Nanjing has always played the role of "high importance and coordination". The research is significant to rationally allocate the innovation resources of Chinese materia medica industry in the Yangtze River Delta, strengthen the construction of the innovation network relying on the resource-core cities, and accelerate the high-quality development of the integration of traditional Chinese medicine in the Yangtze River Delta.
