城市协同创新与绿色技术转移的互动关系:基于创新价值链循环视角

Interactive relationship between urban collaborative innovation and green technologytransfer: based on the perspective of the innovation value chain cycle

基于创新价值链理论,构建了城市协同创新与绿色技术转移互动机制分析框架,利用高校、科研机构和企业绿色专利合作以及绿色技术转移微观大数据,刻画了中国2010—2020年278个地级及以上城市绿色技术研发合作网络和绿色技术转移网络,并采用联立方程组模型对两者互动关系、作用渠道进行了实证检验,以及讨论了区域产学研政策协同的调节作用。研究发现:①城市协同创新与绿色技术转移具有互相促进的正反馈机制,体现出绿色创新价值链上下游之间的互促循环关系。②通过分解城市协同创新及绿色技术转移为拓展边际和集约边际,发现两者互动关系仅体现在拓展边际层面,城市节点快速嵌入城市协同创新与绿色技术转移网络,但城市间合作研发与技术转移强度相对偏低。③城市协同创新与绿色技术转移互动关系仅在本城市技术转移的空间维度生效、具有局部地区属性,全国性的绿色技术创新价值链循环格局尚未形成。④基于文本分析法构造了区域(省级)政策协同指标,发现区域产学研政策协同强化了城市协同创新对绿色技术转移的促进关系,反之却不成立,产学研政策主体和政策工具的协同水平均有待提高。最后,针对结论提出了对策建议,包括加强绿色技术协同创新,充分发挥不同创新主体以及各地区的不同创新优势,提高绿色技术协同创新能力;畅通绿色技术转移渠道,开展共性关键技术研发和转移转化应用,促进绿色技术供给与需求之间的良性互动;提升产学研政策协同水平,加强产学研政策制定部门协调沟通,增强产学研供给政策、需求政策以及环境政策的协同性。

Based on the innovation value chain theory,this study constructed an analytical framework for the interaction mechanism between urban collaborative innovation and green technology transfer and used the green patent cooperation and green technology trans⁃fer micro-big data of universities,scientific research institutions,and enterprises to describe the green technology R&D cooperation net⁃work and green technology transfer network of 278 cities in China from 2010 to 2020.The simultaneous equation model was used to em⁃pirically test the interaction mechanism,and the moderating effect of industry-university-research policy coordination was analyzed.The results showed that:①Urban collaborative innovation and green technology transfer had a positive feedback mechanism that pro⁃moted each other,which reflected the mutual promotion cycle relationship between the upstream and downstream of the green innova⁃tion value chain.②By decomposing urban collaborative innovation and green technology transfer into extensive margin and intensive margin,this study found that the interactive relationship between the two was only reflected at the extensive marginal level,and the number of cities was quickly embedded in the urban collaborative innovation and green technology transfer network,but the intensity of cooperative R&D and technology transfer needed to be further improved.③The interactive relationship between urban collaborative in⁃novation and green technology transfer was only effective in the spatial dimension of the inner city,and showed local regional attributes.The national green technology innovation value chain cycle pattern had not yet formed.④Based on the text analysis method,this study constructed a regional policy synergy index and found that the industry-university-research policy collaboration strengthened the promo⁃tion relationship between urban collaborative innovation and green technology transfer,but not vice versa.The level of collaboration be⁃tween industry-university-research policy subjects and policy tools needed to be improved.Finally,according to the conclusions,coun⁃termeasures and suggestions are put forward,including strengthening collaborative innovation in green technologies by fully utilizing the innovative advantages of different entities and different regions,enhancing the capacity for collaborative innovation in green technol⁃ogies,establishing effective channels for the transfer of green technologies,conducting research and development as well as application of common key technologies,promoting a positive interaction between the supply and demand of green technologies,elevating the level of policy coordination among industry,academia,research,and government by enhancing communication and coordination between de⁃partments responsible for policy formulation,and fostering synergy among policies related to the supply and demand of industry-univer⁃sity-research collaboration as well as environmental policies.
