【摘要】：目前京津冀区域医药产业已经形成一定规模的专利合作网络。基于2011—2015年间的专利数据,以京津冀区域医药上市企业为搜索起点,依据组织间共同申请专利行为获取区域专利合作网络;在此基础上采用社会网络以及渗流理论分析方法解析该网络结构;最后结合上市企业年报数据,实证该网络结构对上市企业专利产出的影响。研究结果显示:京津冀区域医药产业专利合作网络整体以及北京地区子网和天津地区子网都是连通的,并且该网络整体的连通性主要由北京和天津地区所属结点来维持;该区域上市医药企业专利产出受到企业自身拥有的子网内以及子网间连接数量的正向影响,受其所属子网内部连通程度的负向影响。
[Abstract]:At present, the Beijing-Tianjin-Hebei regional pharmaceutical industry has formed a certain scale of patent cooperation network. Based on the patent data from 2011 to 2015, taking the listed pharmaceutical enterprises in Beijing, Tianjin and Hebei as the starting point, the regional patent cooperation network is obtained according to the joint patent application among the organizations. On this basis, the network structure is analyzed by using social network and seepage theory. Finally, the influence of the network structure on the patent output of listed enterprises is demonstrated by combining the annual report data of listed enterprises. The results show that: the whole patent cooperation network of Beijing-Tianjin-Hebei region and the subnet of Beijing and Tianjin are all connected, and the overall connectivity of the network is maintained by the nodes of Beijing and Tianjin; The patent output of the listed pharmaceutical enterprises in this region is positively affected by the number of connections within and between subnets owned by the enterprises themselves and negatively affected by the degree of connectivity within the subnets to which they belong.
