基于ERGM的协同创新网络形成影响因素实证研究

An Empirical Study on the Determinants of Collaborative Innovation Network Formation:Based on the ERGM

以电信产业申请并授权的合作专利为数据基础,从社会网络视角,构建企业、大学和研究院所间协同创新网络,并识别影响组织间协同创新网络形成的内生网络构型,以及外生节点属性两个维度的影响因素。基于指数随机图模型(ERGM),实证分析了这些因素对协同创新网络形成的影响程度。研究表明:协同创新网络是组织协同关系社会化特征的体现,其形成受内生因素和外生因素的共同作用;协同创新网络中,边结构表现出显著的稀疏效应,网络多涌现易于形成资源共享与交换的星型结构和三角结构;网络中组织的合作开放度和区域同配性,能够增加网络节点间的连接概率,而组织的协同创新能力与组织类型同配对网络中新合作关系的形成,并没有表现出显著的促进作用。

This paper uses the joint patent data of telecommunication industry to construct the collaborative innovation network among industry,university and research institute from the perspective of social network.And identifies the factors of the endogenous network configuration and the exogenous node attribute influencing the formation of collaborative network formed.Based on the Exponential Random Graph Model(ERGM),it analyzes the influence of endogenous and exogenous factors on the formation of collaborative innovation network.The results implicate that collaborative innovation network is the embodiment of collaborative relationship socialization,and its formation is influenced by the interaction of endogenous and exogenous factors.The edge structure of the network shows significant sparse effect.The network is easy to form the star structure and triangle structure for resource sharing and exchange.The cooperative openness and regional matching of the organization in the network can increase the connection probability between network nodes,while the collaborative innovation ability and organization type matching do not play a significant role in promoting the formation of new relations in the network.
