复杂网络视角下中国装备制造业创新网络研究

Research on Innovation Network of Chinese Equipment Manufacturing Industries from the Perspective of Complex Networks

本文基于复杂网络视角,以2016年中国装备制造业前100强企业为主要研究对象,以联合申请发明专利数据作为构建创新网络依据,采用社会网络分析法,从网络结构和网络特征两个角度全面分析了网络发展状况,并进行回归分析,探讨了网络中心度、结构洞对网络创新产出的影响。结果表明:中国装备制造业创新网络结构较为松散、凝聚力较差,国有企业依然是产业主体,但产学研合作不足;网络中心度与创新产出之间成正相关,而以自益型结构洞为主的结构洞限制度在一定程度上对创新产出产生抑制作用。

This paper is based on the perspective of complex networks,taking the top 100 enterprises of Chinese equipment manufacturing industries as the research objects,and taking the I-U-R cooperative patent data as the basis of the innovation networks. We use social network analysis to make a comprehensive analysis on the status of the innovation networks from two aspects which are network structure and network characteristics. Meanwhile,we discuss the effect that centrality and structure hole on innovation output through a regression analysis. The results show that the innovation network of Chinese equipment manufacturing industries is relatively loose and the cohesion is poor. State-owned enterprises are still the main body of industries,but the industrialacademic-research cooperation is poor. The innovation output is positively related to the centrality,while,limit of structure holes which mainly consisting of self-benefit structure holes makes an inhibition effect on innovation output to a certain extent.
