摘　　要：基于2006—2021年中国30个省的碳生产率测算及空间特征,采用邻接、经济和地理矩阵下的空间杜宾模型,实证检验了各影响因素对碳生产率的直接效应和间接效应。研究表明:从空间特征来看,我国碳生产率表现为“发达聚集,欠发达分散”的特征;从作用效果来看,城镇化、产业结构和能源结构对本地区及相邻地区碳生产率均具有显著的抑制作用,经济发展水平具有显著的促进作用,而绿色技术创新和FDI对本地区碳生产率具有显著的促进作用但对相邻地区具有显著的抑制作用;从作用大小来看,经济发展水平对碳生产率的促进作用最大,绿色技术创新的促进作用最小,FDI的抑制作用最大,能源结构的抑制作用最小;从区域异质性来看,经济发展水平在西部的提升作用不显著;FDI在西部表现出负溢出效应。建议从完善外商政策、降低能源强度、加快绿色技术创新和促进产业结构高级化来助力碳生产率提升。Based on the calculation and spatial characteristics of carbon productivity of 30 provinces in China during 2006—2021,the direct and indirect effects of each influencing factor on carbon productivity were empirically tested by using the spatial Dubin model under adjacency,economic and geographical matrices.The research shows that,from the perspective of spatial characteristics,Chinese carbon productivity shows the characteristics of“developed agglomeration and under-developed dispersion”.From the perspective of effect,urbanization,industrial structure and energy structure all have a significant inhibitory effect on the carbon productivity of the region and adjacent regions,and the level of economic development has a significant promoting effect on the carbon productivity of the region,while green technology innovation and FDI have a significant promoting effect on the carbon productivity of the region but have a significant inhibiting effect on the adjacent regions.From the perspective of effect size,the promoting effect of economic development level on carbon productivity is the largest,the promoting effect of green technology innovation is the least,the inhibiting effect of FDI is the largest,and the inhibiting effect of energy structure is the least.From the perspective of regional heterogeneity,the improvement of economic development level in the west is not significant;FDI shows negative spillover effect in western China.It is suggested to improve foreign policy,reduce energy intensity,accelerate green technology innovation and promote the upgrading of industrial structure to help improve carbon productivity.
