基于 SNA 的生物育种技术专利引用关系研究
Study on Reference Relationship of Bio -Breeding Technology Patents Based on Social Network Analysis
摘要
Abstract
In the background of flourish of bio -breeding technology,a statistical analysis was made a-bout the overall situation of its related patents from the macro perspective.The reference relationships between patents were studied by the social network analysis (SNA)method.The data show that bio -breeding technol-ogy has developed into a relatively mature stage from a rapidly growth stage,and America possesses absolute technical advantages.The results based on SNA further demonstrated that there were obvious phenomenons of technical cross and cooperation existing in bio -breeding field.However,the overall network cohesion index about the reference relationship of bio -breeding technology was lower,which indicated that it would be nec-essary to strengthen the research on core technology patents in bio -breeding field.关键词
