产学协同创新知识网络的发展与演化——基于"双一流"高校的专利数据

以42所“双一流”高校产学联合申请的专利数据作为研究样本,探究我国产学协同创新的发展,并基于社会网络分析法探究知识网络的时空演化规律。研究发现:产学协同创新经历了起步期、跃升期和平稳期三个阶段,且呈现出显著的区域分布特征,其中东部地区的高校及企业产学合作水平处于领先地位,中西部高校产学合作次数增多,西部企业厚积薄发,但中部企业参与产学活动的程度有待加强。产学协同创新知识网络规模不断扩大,但已被利用的知识不及全部知识的半数,未来仍有进一步研究的可能性;知识网络密度随着时间的演化不断提高,但网络仍较为稀疏,知识元素间重组的潜力很大。

The Knowledge Network Development and Evolution of Industry-University Collaborative Innovation:Based on the Patent Data of 42 Double First-Class Universities

liased on the patent tjata of the joint application of industry and University of 42 double first-class universities,this paper explores the development of industry-university collaborative innovation in China.In addition,?it analyses the evolution of knowledge network based on social network method.The results show that.The industry-university collaborative innovation has gone through three stages,the ini tial stage,the leap stage and the stable stage,and shows a significant regional distribution characteristics.Among them,the level of industry-university collaborative innovation of universities and enterprises in eastern region is in a leading position,and the number of industry-university collaborative innovation of u-niversities and enterprises in western regions is increasing.In addition,the number of industry-university collaborative innovation of universities in central region is increasing,but the degree of industry-university collaborative innovation of enterprises in the central region needs to be strengthened.Though the knowl edge network size of industry-university collaborative innovation?continues to expand,the used knowl-edge is less than half of the total knowledge,and further research is still possible.The density of knowl edge network continues to increase,but the network is still relatively sparse,and the potential of knowl edge reorganization is great.
