基于生命周期的航空制造业产业集群知识网络的演化研究

Study on the Evolution of Knowledge Network of Aviation Manufacturing Industry Cluster Based on Life Cycle

知识网络作为知识经济时代的产物,是推动航空制造业技术创新的重要利器,因此研究航空制造业产业集群知识网络的演化具有重要意义。基于1986—2020年上海航空制造业合作申请发明专利数据,运用GEPHI和UCINET构建上海航空制造业专利合作的知识网络,分析处于不同生命周期阶段知识网络的结构演化特征和重要节点演化规律。研究发现:上海航空制造业产业集群知识网络处于成熟期,核心节点增加,节点间的合作关系逐步稳定,但知识交流的效率仍需持续提高。

As a product of the era of knowledge economy,knowledge network is an important tool to promote technological innovation in aviation manufacturing industry.It is of great significance to study the evolution of knowledge network in aviation manufacturing industry clusters.Based on the data of aviation manufacturing industry jointly applied for invention from 1986 to 2020,GEPHI and GEPHI were used to build the knowledge network of patent cooperation in Shanghai aviation manufacturing industry patent cooperation.The structural evolution characteristics and evolution law of important nodes of the knowledge network at different life cycle stages were analyzed.It was found that the knowledge network of Shanghai aviation manufacturing industry cluster was in the mature period,the cooperative relationship between nodes was gradually stable,but the efficiency of knowledge exchange still needed to be continuously improved.
