供给视角下绿色技术创新的空间溢出效应研究

The Spatial Spillover Effect of Green Technology Innovation from the Perspective of Supply

在绿色转型发展背景下,开辟新视角研究绿色技术创新具有重要意义。从技术供给的视角出发,运用空间杜宾模型估计了企业、科研院所和高校三个主体对绿色技术创新的影响。研究结果显示:企业和科研院所的技术供给均对本地区乃至整体的绿色技术创新发展有正向促进作用,并且科研院所技术供给的贡献要高于企业;而企业技术供给的空间溢出效应为负,同时,高校技术供给的扩大并不利于本地区和周边地区的绿色技术创新发展。据此,提出了要强化创新主体科技力量、推动产学研深度融合等相关参考建议。

In the context of green transformation and development,it is of great importance to open up a new perspective to study green technology innovation.The spatial Durbin model is utilized in this paper to assess the effect of enterprises,scientific research institutes,and universities on green technology innovation,with a particular focus on technology supply.The evidence demonstrates that the technology supply of enterprises and scientific research institutes has a beneficial influence on the advancement of the development of green technology innovation in this region and as a whole,and the contribution of technology supply of scientific research institutes is higher than that of enterprises;while the spatial spillover effect of technology supply of enterprises is negative;at the same time,the expansion of technology supply of universities is not conducive to the development of green technology innovation in this region and surrounding areas.On the basis of this,some relevant suggestions are put forward,such as augmenting the scientific and technical potency of the primary innovation body,encouraging the profound amalgamation of industry,university and research institute,and so on.
