摘要
不同阈值水平的技术相似关系可以在一定程度上反映产业内的技术竞争情况,由此构建了全球研发领先的88家通信及技术设备制造类企业的技术相似关系网络和合作关系网络,利用负二项回归模型分析了技术相似关系对创新绩效的作用。分析结果表明:当技术相似度阈值在0.3和0.5水平时,技术相似关系负向影响创新绩效,合作直接关系部分或完全中介调节两者关系。
Different thre shold leyel of technical similarity relation could reflect technology competition s i tuation in industry to some degree , then make research on influence of technical similarity relation on the innovation performance based on the technical similarity network and the cooperative network of 88 firms in the telecommunication and technology ha rdware industry by negative binomial regression models, the analysis shows that the threshold level at 0. 3 and 0. 1 bring negative effects on the innovation performance, and the cooperative relation is a partial or complete mediator between threshold andinnovation performance.
