研发投入与企业创新绩效——企业研发团队网络结构调节作用研究

R D Investment and Firm Innovation Performance—— A Study on The Mediating Role of R D Team’s Network Structure

摘要:

当前企业研发投入与创新绩效关系在学术界存在争议,争议产生原因尚无定论。基于企业网络理论,引入研发团队网络结构试图解释研究结论不一致的原因,选取汽车产业157家上市公司为样本进行实证研究,结果表明：企业研发投入与创新绩效显著正相关,当研发团队E-I指数较高或网络密度、网络中心势较低时,研发投入与创新绩效正相关关系不显著；当研发团队E-I指数较低或网络密度、网络中心势较高时,研发投入与创新绩效正相关关系显著增强。

Abstract:

At present, the relationship between the R D input for enterprise and the innovation performance is controversial in the academic circle, and the reason for the controversy is still in doubt.Drawing on the enterprise network theory (ENT), the article introduces the network structure of the team engaged in R D, attempting to explain why the outcome of these studies is different from each other, i.e. why the controversy exists. Therefore, we select 157 automobile companies as samples to carry out empirical analysis and discover the R D input and innovation performance is positively related. When the R D team own high EI index ,low density or low centralization, the R D input and innovation performance are not obvious positive correlation; while when the R D team own low EI index ,high density or high centralization , the positive correlation between the R D investment and innovation performance significantly enhanced.
