【摘要】 厘清技术创新网络演化的动因,可以发现网络演化本质,从而为网络组织治理提供依据.本文基于网络节点间关系的多维邻近性与网络结构,利用德温特和Thomson Innovation专利数据库,对全球OLED产业联合申请发明专利数据进行检索和整理,采用指数随机图模型,就地理、社会、技术、组织、制度5种不同邻近性对OLED技术创新网络的演化动力进行实证分析.研究发现:OLED技术创新网络目前处于快速发展的跃升期,地理邻近性对其演化发展的重要性相对降低,制度和组织邻近性一直发挥着较为稳定的促进作用,社会和技术邻近性所占比重逐渐增加,成为推动创新网络发展演化的重要动力.更多还原

【Abstract】 To clarify the driving forces of technological innovation network evolution can discover the essence of network evolution and provide a basis for network organization governance. Based on the multi-dimensional proximity of network nodes and the network structure,it used the Derwent and Thomson Innovation patent databases to retrieve and sort out the joint application patent data of the global OLED industry. Using the exponential random graph model( ERGM),it made an empirical analysis on the effects of geographical,social,technological,organizational and institutional proximities on the formation of innovative cooperative relationships within technological innovation networks. It finds that the innovation network of OLED technology is now in the leap period of rapid development; geographical proximity’s effect on its evolution is relatively reduced; institutional and organizational proximities have always played more stable roles;social and technological proximities are gradually more important in promoting the development of innovation network.更多还原
