摘要:  选取2003~2019年长江经济带11个省份制造业及其细分行业为研究对象,采用超效率SBM模型测算制造业碳排放效率,并综合分析其动态演进、空间分异和行业分布特征,最后运用空间计量模型对各区域制造业碳排放效率的收敛特征进行系统分析。研究发现:(1)长江经济带11省份制造业碳排放效率不断提升,上游和中游地区碳排放效率的区域差异呈减少态势,长江经济带总体和下游各地区碳排放效率两极分化显著;(2)长江经济带制造业碳排放效率呈现出“下游—中游—上游”依次减少的分布特征,其中高碳制造业碳排放效率分布呈现出空间异质性特征;(3)长江经济带总体和下游地区制造业碳排放效率均存在σ收敛、绝对β收敛和条件β收敛,上游和中游地区制造业碳排放效率均不存在σ收敛,但存在绝对β和条件β收敛,且经济水平、产业结构、外商直接投资水平、城镇化率和绿色技术创新对制造业碳排放效率变化率的影响具有显著的异质性。提升长江经济带制造业碳排放效率的主要路径有:优化制造业区域分工协作和生产力布局;推进产业结构高端化转型;提升绿色技术创新水平。

Abstract: This research focuses on the manufacturing industry and its sub-sectors in 11 provinces within the Yangtze River Economic Belt from 2003 to 2019.The paper utilizes the Super Efficiency SBM model to calculate the carbon emission efficiency.It comprehensively analyzes the dynamic evolution, spatial differentiation, and industry distribution characteristics.Finally, a spatial econometric model is introduced to systematically analyze the convergence characteristics of carbon emission efficiency in various regions.The research reveals the following findings: (1) The carbon emission efficiency of the manufacturing industry continued to improve, and the regional differences in carbon emission efficiency in the upper and middle reaches showed a decreasing trend, and the carbon emission efficiency of the overall Yangtze River Economic Belt and the downstream regions showed a significant polarization; (2) The carbon emission efficiency of the manufacturing industry showed a decreasing distribution of "downstream, midstream and upstream", and the distribution of carbon emission efficiency of the high-carbon manufacturing industry showed spatial heterogeneity.(3) Convergence characteristics are observed in the overall and downstream regions of the Yangtze River Economic Belt.The upstream and midstream regions show no σ-convergence but exhibit absolute β-convergence and conditional β-convergence.The impact of economic level, industrial structure, foreign direct investment level, urbanization rate, and green technological innovation on the change rate of urban carbon emission efficiency has significant heterogeneity. The main paths to enhance carbon emission efficiency in the manufacturing industry include optimizing regional collaboration and productivity layout; promoting the high-end transformation of industrial structure; improving the level of green and low-carbon technology.
