Abstract:

This study is mainly concerned with the short-term and long-term impact of social networking environment on R&D efficiency of enterprises, and the evaluation of actual R&D efficiency of listed companies in China. Many enterprises are consciously developing their own external knowledge resources in R&D activities. However, there are some debates about the direction of social network's impact on R&D efficiency. In order to study the different influence on the R&D performance of firms which are in different positions of social network, this paper constructs a two-mode social network model of the listed companies in China, and 178 listed companies' R&D performances are analyzed by a three-stage DEA model which considers time lag of both the network location indicators and the input-output indicators. The results show that the social network position has a significant effect on the listed enterprise' R&D performance, but different indicators of social network position have different effects, in particular, the number of the social network connections of the firm (such as degree and structural holes) has a short-term impact on R&D performance, and the centrality of the firm in the network (such as closeness and betweenness) has a long-term effect on the R&D performance. At the end of the study, we sum up the empirical results by use of some existing theories.
