| 摘 要： | 传统观点认为，在社会网络中占据一个能获取更多外部资源的位置，对于企业R&D绩效提升来说是一种优势。然而一些实证研究结果并不支持这种观点。本研究对这种理论和现实的矛盾进行了分析。经过文献的梳理，我们认为技术积累是社会网络位置和企业R&D绩效之间的重要调节变量。利用中国上市公司数据，本研究构建了中国上市公司的二模社会网络，并用结构洞、点度中心性、中介中心性、接近度中心性测量了焦点企业的社会网络位置。企业R&D绩效则通过DEA方法测量得出。面板数据的门槛回归分析结果表明技术积累的门槛效应是显著的，但对不同性质的社会网络位置的门槛作用有差异。本研究从技术积累的视角解释了社会网络位置和企业R&D绩效之间的非线性关系，为企业管理决策提供了新的理论基础。

Social network position and firms R&D performance |
| |
| Abstract: | Some previous studies suggested that a position which can make a firm get more external resources in social network means the firm has advantages for improving its R&D performance. However, the results of some empirical studies did not support this opinion. In this study, we analyse this contradiction between theory and actual. We put forward a new perspective to understand the relationship between social network position and R&D performance. Specifically, we argue that the technology accumulation has a threshold effect in the relationship. We constructed a bipartite social network of Chinese listed firms. The network position of focal firms is measured by structural holes, degree centrality, betweenness centrality, and closeness centrality. Moreover, we calculate the firms’ R&D performance by Data Envelopment Analysis (DEA) method. The results of the panel threshold regression model show that the technology accumulation’s threshold effect is significant. We also find different types of network positions have different influences on a firm’s R&D performance. Previous studies have shown that network position’s influence on R&D performance is non-linear. However, we find that previous studies about the nonlinear relationship of network position and R&D performance always focus on external impact and the firm’s adaptive capacity to the environment, but few studies are related to the firm’s internal technology accumulation’s influence on firm’s demand for external resources. Finally, we discussed the study results combined with previous studies. |
