摘　　要：科学知识是企业突破技术难题的关键,是企业提升创新绩效的重要因素。以159家医药上市公司为研究对象,搜索其与高校、科研机构等创新主体的合著论文,构建2007-2021年的动态科学合作网络,运用负二项回归模型来探究自我中心网络特征对企业创新绩效的影响:(1)自我中心网络规模对企业创新绩效有显著正向影响;(2)自我中心网络平均路径长度负向影响企业创新绩效;(3)平均路径长度在自我中心网络规模与创新绩效的关系中有显著负向调节作用。Scientific knowledge is a magic weapon for enterprises to break through technical difficulties and an important factor for companies to enhance innovation activities.Based on the data of 159 listed companies in the pharmaceutical industry,collecting co-authored papers between companies,universities,research institutions and other innovative entities,constructing a scientific collaboration network of listed companies from 2007 to 2021 and then using negative binomial regression to explore whether egocentric network characteristics have an impact on enterprises innovation performance.The following conclusions are drawn:Egocentric network size has a significant positive impact on the firm innovation performance.The average path length of the egocentric network negatively affects enterprise innovation performance.The average path length negatively moderates the relationship between egocentric network size and enterprise innovation performance.

关 键 词：自我中心网络 科学合作 创新绩效 网络规模 平均路径长度
