学缘关系视角下创新网络演化研究——以中国科学技术大学校友企业为例

Research on the Evolution of Innovation Network from thePerspective of Consanguinity of Scholarships——Take the Alumni Enterprise of the University of Science andTechnology of China as an Example

中国科学技术大学产生的“科大系”已成为众多领域创新创业的重要力量。基于“科大系”人工智能领域在2000-2021年的合作数据,分阶段构建创新网络,运用社会网络分析方法,从整体网络与网络演化阶段特征两方面探讨基于学缘关系形成的创新网络的演化规律。研究发现:①创新网络演化阶段性明显,网络规模呈现爆发式增长,网络密度和网络凝聚力逐渐下降;②在节点网络位置演化方面,网络中存在一些实力强大的核心节点,网络的核心-边缘结构特征愈发凸显;③在网络结构演化方面,节点扮演的角色和创新倾向也在不断变化。据此提出:推动具有同一学缘关系的企业间战略联盟的建设以破除企业间的隔阂;后发地区要积极扶持高校系高科技企业的发展以促进地区发展等。

The enterprises founded by alumni of the University of Science and Technology of China have become an important force for innovation and entrepreneurship in many fields.Based on the cooperation data of alumni enterprises of University of Science and Technology of China in the field of artificial intelligence from 2000 to 2021,the innovation network was built in stages.Using the social network analysis method,the evolution law of innovation network based on academic relationship was discussed from the aspects of overall network and network evolution stage characteristics.It is found that the evolution of innovation networks is obvious,the network scale shows explosive growth,and the network density and network cohesion gradually decline.In terms of node network location evolution,there are some powerful core nodes in the network,and the core-edge structure characteristics of the network are becoming more and more prominent.In the evolution of network structure,the role and innovation tendency of nodes are also constantly changing.It is proposed to promote the construction of strategic alliances between enterprises with the same academic relationship to break down the barriers between enterprises,and the late-developing areas should actively support the development of high-tech enterprises in colleges and universities to promote the development of the region.
