我国医药企业产学研合作的社会网络分析——以176家上市公司为例

Study on Industry-University-Research Collaboration of China's Pharmaceutical Companies Based on Social Network Analysis——Taking 176 Listed Companies as Examples

在手工收集我国176家医药上市公司1992—2019年产学研合作数据的基础上,利用社会网络分析方法对合作网络的时空演化过程进行刻画和分析,探讨发展规律。研究表明:我国医药企业产学研合作网络规模稳步增长,网络密度较低;网络结构呈现去中心化趋势,合作模式趋于固定化;区域内部合作比例下降,跨区域合作具有小世界特点;区域合作发展不平衡,应进一步提高区域协同创新能力。

Based on the manual collection of cooperative innovation data of 176 pharmaceutical listed companies in China from 1992 to 2019,this paper uses social network analysis methods to describe and evaluate the evolution process of network from the perspective of time and space,so as to explore the law of development.The research found that the scale of industry-university-research collaboration network of listed pharmaceutical companies in China has been growing steadily,and the network density is low.The cooperative network structure is decentralized,and the cooperation mode is becoming more fixed.The proportion of intra-regional collaboration is decreasing,while the cross-regional collaboration has the characteristics of small world.The development of regional collaboration is unbalanced,and collaborative innovation needs to be strengthened.
