中文摘要：
技术创新网络节点退出会影响网络稳定性甚至导致网络瓦解。以电真空材料和蓄电池行业专利数据为例,采用社会网络分析和统计分析法,从个体层、关系层和网络层3个维度对影响企业退出网络的因素进行了实证研究,结果表明：企业资源能力越强、节点中心度越高、规模和密度越大,越能降低企业退出意愿;有合作历史经验的企业更倾向于留在网络中。
英文摘要：
Nodes leaving technology innovation network will affect stability of the network, even lead to network collapse. This paper analyzes influence factors of nodes leaving as examples of the industry patent data of the electrical vacuum materials and battery. Influence factors are considered from individual levels, relationship levels and network levels, and social network analysis and statistical analysis are used. It argues that the more resource capacity and network power, the larger nodes size, the greater network density, numbers of partners and cooperation, will reduce the possibility of the node leaving the network, and the enterprise with cooperation experience will prefer to stay the network.
