基于产学联合申请专利的合作网络动态演化研究——以“双一流”建设高校为例

Research on the Dynamic Evolution of Cooperative Network based on Industry-University Joint-patent Data——An Analysis of "Double First-Class" Universities

从社会网络视角,以1985-2016年产学联合申请并授权的专利数据为基础,运用社会网络分析方法,构建产学合作网络与跨区域合作网络,并分析合作主体的基本特征与合作网络动态演化过程。结果发现:中国产学合作模式从“一校-一企”向“多校-多企”转变,跨区域合作模式也从“一省-其它一省”向“一省-其它-多省”演化,合作深度逐渐增加,但合作广度仍需进一步拓展;高校与企业在合作网络演化中相对稳定,参与合作的高校相对集中且多为综合性大学,企业合作集中在能源领域和高技术领域;“地理邻近”仍是制约产学合作的主要因素,总体上区域内合作数量占比依然大于跨区域合作;产学合作网络与跨区域合作网络具有显著的非对称性特征。

From the perspective of social network, using the industry-university joint patent data from 1985 to 2016, the paper uses the method of social network analysis to construct the industry-university cooperative network and the inter-regional cooperative network.And it analyzes the basic characteristics of participants and the dynamic evolution of the network.The results show that the mode of cooperation changes from "one university-one enterprise'' to "universities-enterprises", and the inter-regional cooperation mode evolves from "one province-another province" to "one province-other provinces", the depth of cooperation is gradually increasing, but the cooperative width still needs to be further strengthened.Enterprises and universities maintain relative stability in the evolution, universities are concentrated and mostly comprehensive, and the fields of enterprises are concentrated in energy and high technology industry."Geographic proximity" is a restrictive factor of industry-university cooperation, the proportion of intra-regional cooperation is greater than inter-regional cooperation.The industry-university cooperative network and the inter-regional cooperative network have significant asymmetrical characteristics.
