Under the meta-frontier method, an analysis and comparison have been made of the regional disparities in total-factor energy efficiency throughout China during the year 2000 to 2008. Additionally, a quantitative TGR-based analysis has been made on the technology gap of energy utilization. Subsequently, a test is utilized for investigating total-factor energy efficiency's convergence of overall country and three major areas. Empirical conclusions drawn are as follows: i) the overall level of China's total-factor is on the low side and its regional disparities are significant during the sample period and there exists tremendous room for energy conservation and emissions reduction. Additionally, there are significant gaps on production technology among China's three major areas; ii) there are not convergences of total-factor energy efficiency among overall China and its three major areas, and the risk of the widen gap of total-factor energy efficiency among China's provinces still exist.%基于省际面板数据和meta-frontier方法,利用数据包络分析方法构建非参数前沿,分析比较了2000 ～2008年中国全要素能源效率的区域差异,采用“技术差距比”衡量中国三大地区之间能源利用的技术差距,并在此基础上运用收敛性分析考察了全国和三大地区全要素能源效率的趋同情况.结果表明:中国全要素能源效率整体水平较低且区域差异显著,存在巨大的节能减排潜力；三大地区生产技术差距明显；共同前沿和区域前沿下的σ检验结果均显示全国和三大地区全要素能源效率不存在收敛趋势,表明中国各省份全要素能源效率的差距有进一步扩大的危险.
