摘　　要：为从理论上阐述绿色技术创新对碳减排的影响作用,基于2013—2022年全国30个省份的面板数据,运用双向固定模型、门槛模型和空间滞后模型实证分析绿色技术创新对碳减排的影响路径。研究结果表明,绿色技术创新对抑制碳排放有显著的作用,中部地区的的抑制作用最为显著,非资源型省份比资源型省份更能显著抑制碳排放;教育重视程度、政府支持度和产业结构升级是绿色技术创新促进碳减排的关键路径;长江三角洲的城市群之间的绿色技术创新关联程度较高,同时因为虹吸作用使空间上呈现反向溢出效应,从长远来看,绿色技术创新的成果最终会辐射周围地区。In order to theoretically explain the impact of green technology innovation on carbon emission reduction,based on the panel data of 30 provinces in China from 2013 to 2022,the bidirectional fixed model,threshold model and spatial lag model were used to empirically analyze the impact path of green technology innovation on carbon emission reduction.The results show that the green technology innovation has a significant effect on curbing carbon emission.The inhibitory effect is most significant in the central region,and non-resource provinces are more able to significantly suppress carbon emissions than resource-based provinces.Education importance,government support and industrial structure upgrading are the key paths for green technology innovation to promote carbon emission reduction.The correlation degree of green technology innovation among urban agglomerations in the Yangtze River Delta is relatively high,and the siphon effect causes a reverse spillover effect in space.However,in the long run,the achievements of green technology innovation will eventually radiate to the surrounding areas.
