科学合作网络、知识多样性与企业技术创新绩效

科学合作在科学知识生产中扮演着重要角色，而科学研究所产生的科学知识对于企业技术创新至关重要。运用2000-2017年新能源汽车产业相关学科在web of science刊载的32715家中国组织参与的合作论文585348篇，构建组织间科学合作网络139090个（个体网）。同时从德温特数据库下载了1893家中国组织在新能源汽车产业申请的专利16112条，将参与了科学合作（合作论文）与产生了技术创新绩效（专利申请）的组织进行匹配，最终聚焦于174家企业，利用面板数据，实证分析我国新能源汽车产业科学合作网络关系如何影响企业技术创新绩效。研究发现，企业在网络中的关系广度与关系强度均能正向影响企业技术创新绩效，关系强度比关系广度对企业技术创新绩效的影响更直接；知识多样性（学科多样性和技术多元化）中介于网络关系对企业技术创新绩效的影响，学科多样性中介于关系强度对企业技术创新绩效的影响，而关系广度则通过技术多元化影响企业技术创新绩效；研究还发现，企业进行学科多样性和技术多元化均有利于其提升技术创新绩效。

A study of scientific collaboration network,knowledge diversity and firm innovation

Scientific collaboration plays a key role in producing scientific knowledge, which is vital to the success of firm technological innovation. We investigate 585,348 co-authored research papers published in the Web of Science during 2000 to 2017 in disciplines relevant to the new energy vehicle industry. We discovered 139,090 inter-organizational scientific collaboration ego-networks involving 32,715 Chinese organizations. Meanwhile, we collected data on 16,112 patents applied by 1,893 Chinese organizations in the industry from the Derwent database. We use co-authored papers and patents applied by 174 focus firms and other organizations as panel data to empirically analyze how scientific collaboration network relation affects firm innovation in Chinese new energy vehicle industry. The study findings show, both relation breadth and relation strength in the scientific collaboration network can positively affect firm innovation, and the relation strength has a more direct impact than the relation breadth. Knowledge diversity (interdisciplinary and technology diversity) are mediating variables between network relations and firm innovation. Interdisciplinary is a mediating variable between relation strength and firm innovation, while relation breadth influences the firm innovation through technology diversity. Besides, both interdisciplinary and technology diversity are beneficial to firm innovation.
