中文摘要：

本文首次采用基于投入冗余的全要素生产率指数（ISP）来重新测度和分解中国1985-2009年29个省份的能源生产率。研究表明，中国能源生产率年均提高2．89％，转折点发生在2002年。在此之前，能源技术变化是能源生产率提升的主要驱动力量，之后，能源技术效率变化推动了中国能源生产率的稳步上升。中、西部地区与东部地区的能源生产率水平差距越来越大，技术变化是导致东、中、西部地区之间差距的主要原因；东部地区呈现“高能效-高增长”的经济发展模式，而中、西部地区则表现为“低能效一高增长”的经济发展模式。全部省份的能源生产率均得到提升，最佳实践省份越来越多，但是省份之间的追赶效应只有0．36％。

英文摘要：

Based on Input Slack-based Total Factor Productivity Index, this paper re-measure and decompose energy productivity in 29 provinces in China 1985 2009. Studies have shown that as following. China＇s energy productivity average of 2.89%, and after 2002, the role of technical efficiency is more significant. In the western and eastern growing gap between the energy levels of productivity, technological change is causing the the gap between eastern, central and western, The eastern region showing a ＂high efficiency-high-growth＂ economic development model, while the central and western regions is shown as ＂inefficient-high growth＂ model. All the provinces of the energy production would be enhanced, more and more provinces are the best practices provinces, based on static efficiency-dynamic productivity matrix analysis shows that Chinese provinces show ＂getting stronger, getting weaker＂ trend.
