网络密度、产学研知识距离对二元型创新绩效的影响

Research on the influence of network density and knowledge distance among industry-university-research institutes on the performance of dual innovation

产学研协同创新网络模式对提升区域创新绩效至关重要。为了探究跨区域产学研协同创新网络机制,基于2011—2020年重庆市、四川省科技进步奖数据和专利数据构建“成渝双城经济圈”协同创新网络,并采用负二项回归模型来探究产学研知识距离、网络密度与探索型、应用型创新绩效之间的联系。结果表明:大学、科研机构、企业之间的知识距离存在异质性且对二元型创新绩效产生影响,企业间知识距离与应用型创新绩效负相关,企业与大学间知识距离与应用型创新绩效呈U型关系,大学与企业间知识距离与探索型创新绩效正相关,大学间知识距离与探索型创新绩效呈负相关,科研机构在产学研协同创新过程中对二元型创新绩效的影响不显著。网络密度与应用型创新绩效负相关,对探索型创新绩效影响不显著。研究可为区域间产学研协同创新伙伴的选择提供参考,同时能为成渝双城经济圈协同创新管理提供启示。

The network model of industry-university-research collaborative innovation is of great importance to the improvement of regional innovation performance.In order to explore the cross regional industry university research collaborative innovation network mechanism,a collaborative innovation network of“Chengdu Chongqing Double City Economic Circle”is constructed based on the data of science and technology progress awards and patent data of Chongqing and Sichuan province from 2011 to 2020.The negative binomial regression model is used to explore the relationship between the knowledge distance,network density and the performance of exploratory and applied innovation.The results show that the knowledge distance among universities,scientific research institutions and enterprises is heterogeneous and has an impact on the performance of dual innovation.The knowledge distance between enterprises is negatively correlated with the performance of applied innovation;the knowledge distance between enterprises and universities is U-shaped with the performance of applied innovation;the knowledge distance between universities and enterprises is positively correlated with the performance of exploratory innovation,and the knowledge distance between universities is negatively correlated with the performance of exploratory innovation.Scientific research institutions have no significant impact on the performance of dual innovation in the process of industry-university-research collaborative innovation.Network density is negatively correlated with the performance of applied innovation,and has no significant impact on the performance of exploratory innovation.The research can provide reference for the selection of regional industry-university-research collaborative innovation partners.
