基于对主体网络位置特征及网络密度对技术研发网络探索式创新影响机理分析,构建了网络地位、结构洞以及网络密度影响探索式创新的理论模型,结合2007-2016年间215家企业的联合申请专利数据,运用负二项回归分析进行了实证研究。研究表明：网络地位、结构洞均与低碳技术探索式创新均呈倒U型关系,且网络地位的影响程度高于结构洞；网络密度对网络地位和结构洞与探索式创新之间的关系分别起到正向和负向的调节作用。在此基础上,提出了打破稀疏网络中心企业的路径依赖、加强稀疏网络中介企业的信息枢纽性、提高紧密网络中介企业信息异质性、强化紧密网络中心企业引领示范效应四个方面的建议。

Based on a influencing mechanism analysis of network postions and network desity on explorative innovation in R D colloboration networks, a theretical model regarding network prominence, structural holes and network density on explorative innovation is build. This is further tested on sample of 215 firms with joint-filing patents in China from 2007 to 2016 with negative binomial regression. Empirical results reveal that both network prominence and structural holes have inverted U-shaped effects on explorative innovation, and the former position exerts greater influence than the latter one. Network density positively moderates the link between network prominence and explorative innovation and negatively moderates the link between structural holes and explorative innovation. In sparse network, governments can emphasize on breaking path dependence of central actors while strengthening the hub effects of bridging actors. In dense network, governments can highlight enhancing the demonstration effect of central actors while improving information heterogeneity of bridging actors.
