基于社会网络的建筑行业科技创新主体合作网络演化研究——以“华夏建设科学技术奖”为例

Research on the Evolution of the Cooperation Network of Science and Technology Innovation Subjects in Construction Industry Based on Social Networks-Taking Huaxia Award as an Example

对创新主体合作情况进行研究,探究建筑行业创新主体合作现状和演化趋势。根据2007—2021年“华夏建设科学技术奖”获奖情况,以社会网络分析的视角对创新主体合作整体、个体网络及演化特征进行分析。结果表明,创新主体多通过跨类型机构合作方式推进建筑科技创新,“校—企”合作是当前的主要合作模式;合作网络规模不断扩展,创新主体逐渐向一个联通子图聚集,形成具有紧密关系的“小世界”;以同济大学、清华大学为代表的创新主体处于合作网络核心位置,促进边缘主体的建设科技创新合作。

Research on the cooperation of innovation subjects is conducted to explore the current situation and evolution trend of the cooperation of innovation subjects in the construction industry.Based on the awards of “Huaxia Construction Science and Technology Award” from 2007 to 2021,the overall and individual networks and evolution characteristics of the cooperation of innovation subjects from the perspective of social network analysis were analyzed.The results are as follows.Innovation subjects mostly promote construction science and technology innovation through cross-type organisational cooperation,and “school-enterprise” cooperation is the main mode of cooperation.The scale of the cooperation network is constantly expanding,and the innovation subjects are gradually gathering to a connected subgraph,forming a “small world” with a close relationship.The cooperation network of Tongji University is the most important one.The scale of the cooperation network is expanding,and innovation subjects are gradually gathering to a connected subgraph,forming a “small world” with close relationship.The innovation subjects represented by Tongji University and Tsinghua University are at the core of the cooperation network,promote the construction of marginal entities and cooperation in scientific and technological innovation.
