| 摘 要： | 根据我国资源型城市的分类,选取106个资源型城市(成长型13个、成熟型58个、衰退型22个、再生型13个)作为研究对象,综合运用DEA模型和SE-SBM模型对其碳排放效率进行研究。研究发现,不同阶段的资源型城市碳排放效率存在显著差异,而同一类型资源型城市碳排放效率在规模有效性、技术有效性、规模收益和综合效率等方面仍表现出差异化;通过Tobit回归分析发现,经济发展水平、产业结构和城市化率对碳排放效率有不同程度的正向影响,能源强度与碳排放效率则呈现明显的负相关性。研究认为,提高资源型城市的碳排放效率应根据资源型城市不同发展阶段的特性、差异性和碳排放相关影响因素进行调整。最后针对资源型城市不同阶段的碳排放特征和影响因素提出针对性建议。

Research on Efficiency of Carbon Emission of Resource-based Cities based on DEA Model and SE-SBM Model |

| Abstract: | According to the classification of resource-based cities of China, the paper studies the efficiency of carbon emissions of 106 resource-based cities in China which includes 13 growing resource-based cities,58 mature resource-based cities,22 declining resource-based cities and 13 regenerative resource-based cities by comprehensive use of DEA model and SE-SBM model. The study finds that the carbon emission efficiency are significant differences in the different stages of resource-based cities and carbon emission efficiency of the same type of resource-based cities in scale carbon emission efficiency effectiveness, technical effectiveness, scale and overall efficiency gains are still to differentiate performance. By Tobit regression analysis,the results show that the level of economic development, industrial structure and urbanization rate have varying degrees of positive impact on the efficiency of carbon emissions, while energy intensity shows a significant negative correlation with carbon emission efficiency . The paper concludes that improving the carbon emission efficiency should be based on the characteristics and differences of resource-based cities at different stages and adjusted by relevant factors. At last, the paper makes specific recommendations according to the relevant factors and characteristics of the different stages of resource-based cities. |
