摘　　要：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。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 that the R＆D input and innovation performance is positively related. When the R＆D team owns high EI index, low density or low centralization, the R＆D input and innovation performance do not have obvious positive correlation; while when the R＆D team owns low EI index, high density or high centralization, the positive correlation between the R＆D investment and innovation performance is significantly enhanced.
