“双碳”目标下钢铁企业绿色创新联盟网络的结构演化研究

Structural evolution analysis of green innovation alliance network of steel enterprises under carbon peaking and carbon neutrality goals

以“双碳”目标实现为背景,挖掘2014—2021年与钢铁上市企业联合申请的绿色专利数据,按三年时间窗划分6个时期,运用Ucinet构建各时期钢铁企业绿色创新联盟网络,结合社会网络分析方法探索网络的整体结构和核心节点的演化特点。研究发现:钢铁企业绿色创新联盟网络发展仍处于初级阶段,紧密度不够、流动性较强;钢铁企业绿色创新联盟网络的小世界特性逐步凸显;宝钢股份在6个时期网络演化中均处核心地位,产学研联盟趋势明显。因此,钢铁企业应当广泛开展与其他钢铁企业、高校和组织的合作,同时政府应发挥引导和推广作用,搭建校企绿色创新平台,优化钢铁企业绿色创新联盟网络结构。

With the goal of“double carbon”as the background,the green patent data of joint applications with listed iron and steel enterprises from 2014 to 2021 were explored,and divided into six periods according to the threeyear time window.Ucinet was used to construct green innovation alliance networks of iron and steel enterprises in each period,and the overall structure and evolutionary characteristics of core nodes of the network were explored combined with social network analysis method.The research findings are as follows:the development of network is still in the initial stage,with insufficient tightness and strong mobility.The small world features of the network are initially highlighted.Baoshan Iron&Steel Co.,Ltd.shares occupy the core position in the six stages of the network,the trend of industry-university-research alliance is obvious.Therefore,iron and steel enterprises should carry out extensive cooperation with other iron and steel enterprises,universities and organizations;At the same time,the government should play a guiding and promoting role to build a green innovation platform for universities and enterprises in order to green innovation alliance network of steel enterprises.
