摘要: 利用非期望产出超效率SBM模型和Malmquist全要素生产率指数,计算2011—2020年江苏省各地级市碳排放效率,并对时空差异进行分析。结果表明,各地级市碳排放效率差异显著,总体上呈苏中地区>苏南地区>苏北地区的特征;技术创新是江苏省碳排放效率提升的核心驱动因素,资源配置不合理、规模效率偏低是江苏省碳排放效率未达到生产前沿面的主要原因。

关键词: 超效率SBM模型, 碳排放效率, 时空差异, 江苏省

Abstract: Through the super-efficient SBM model with non-expected output and Malmquist productivity index, the carbon emission efficiency of each city in Jiangsu Province from 2011 to 2020 was calculated and the spatial and temporal differences were analyzed. Results showed that there was a significant difference in carbon emission efficiency among the prefecture-level cities in Jiangsu Province, with the overall characteristics of higher carbon emission efficiency in central Jiangsu than in southern Jiangsu and higher carbon emission efficiency in southern Jiangsu than in northern Jiangsu. The innovation of technology was the core driving factor for the improvement of carbon emission efficiency in Jiangsu Province. Unreasonable resource allocation and low scale efficiency were the main reasons why the carbon emission efficiency in Jiangsu Province had not reached the production frontier.

Key words: super-efficient SBM model, carbon emission efficiency, temporal and spatial differences, Jiangsu Province
