中文摘要：

运用Malmquist方法从地级市层面考察了2000-2010年我国能源消费和全要素生产率的动态变化状况。考虑能源要素投入后,全要素生产率年均增长2.9%,显著高于劳动和资本双要素模型下年均0.2%的增长率,说明节能增效已经成为生产率提高的主要推动力量。进一步将全要素生产率分解为效率改善和技术进步后得出,效率改善和技术进步分别在推动我国＂十五＂和＂十一五＂期间的生产率提高方面起到了显著作用;东部地区在技术进步方面表现出色,中、西部地区则在能效改善方面具有较大优势;要提高区域生产率水平,全国约一半的城市仍然需要从技术进步或效率改善方面加强努力;技术进步是提高我国21世纪整体生产率和实现可持续发展的重点所在。

英文摘要：

This paper employs the Malmquist method to inspect the dynamic changes of China＇s energy consumption and the total factor productivity（TFP） during 2000-2010 at the prefecture-level cities. Given the input of the energy factor, the average annual increase of TFP is 2.9%, much higher than the rate of 0.2% under the two-factor model of labor and capital, which indicates that energy saving and efficiency improvement has become the main driving force for the increase in productivity.When the TFP is further divided into efficiency change（EC） and technical progress, it is found that efficiency change and technical progress both contribute remarkably to TFP growth during 2000-2005;the technical progress in the eastern region is remarkable, while energy changes in the central and western regions have great advantages; in order to raise the level of regional productivity, about half of the cities in China still have to improve the levels of their EC or EP; technical progress will be the key point for the improvement of China＇s productivity and realization of sustainable development in the 21 st century.
