Research on the Structure and Evolution Characteristics of Patent Cooperation Network in China |
| |
| Abstract: | Patents are the carrier of exclusive and novel technical knowledge and a visible result of innovative activities. This paper selects the application data of China's invention patent cooperation from 2006 to 2015, constructs a patent cooperation network in China, analyzes the network indicators of the whole network and the network location of a single node by using social network research methods. And according to the stage characteristics of the patent cooperation network, this paper depicts the evolutionary trend of China's patent cooperation network. The results show that: The scale of China's patent cooperation network is large but the whole is scattered. Colleges and universities and large central enterprises occupy the core position in the network. The largest subgroup of the network has the characteristics of small world. From the perspective of evolutionary trend, China's patent cooperation network has expanded rapidly, network relations have become increasingly close, the importance of nodes in the network has gradually increased, and the network as a whole has deviated toward the core nodes. |
