摘　　要：在“双碳”目标背景下,提高能源使用效率是实现经济绿色转型和可持续发展的重要路径。以江西省2008—2020年间11个地级市为研究对象,基于非期望产出的SBM-DEA模型和Malmquist指数法对能源使用效率进行测度。研究表明:江西省能源使用效率整体呈现上升趋势;区域间差异整体上呈现出“先上升后下降”的趋势;技术效率变动和规模效率变动是推动Malmquist全要素生产率提升的主要动力,而技术进步对全要素生产率提升贡献较小。江西省能源使用效率在时间维度上整体提升,但阶段性波动明显。赣北、赣中和赣南地区在能源使用效率上的差异显著。江西省能源全要素生产率(TFP)指数整体呈现“V”字型变化趋势,表明能源使用效率逐渐提升。Under the background of the"dual carbon"goals,improving energy efficiency is a crucial pathway to achieving green economic transformation and sustainable development.This study focuses on 11 prefecture-level cities in Jiangxi province from 2008 to 2020,utilizing the SBM-DEA model with undesirable outputs and the Malmquist index method to measure energy efficiency.The findings indicate that the overall energy efficiency in Jiangxi province shows an upward trend.The Theil index decomposition results reveal that the regional disparities in energy efficiency first increased and then decreased over time.Additionally,the Malmquist index decomposition results suggest that technical efficiency and scale efficiency are the primary drivers of energy efficiency improvement,while technological progress contributes less to efficiency enhancement.There are significant differences in energy use efficiency among the northern,central and southern regions of Ganzhou.The energy total factor productivity(TFP)index in Jiangxi province as a whole shows a V-shaped trend,indicating a gradual increase in energy use efficiency.
