This research discusses the manufacture Industry energy efficiencies of 30 sectors by Stochastic Frontier Approach based on Cobb-Doulas production function. We find the annual average of energy efficiency between 2003 and 2010 improved slowly,and the difference between sectors is remarkably. 30 sectors is divided into six kinds of level by System cluster analysis,Evidence is found that heavy industry consumed much more energy and its energy efficiency is also high,light industry consumed less energy and its efficiency is low too. Energy consumption structure is a crucial factor which influenced efficiency obviously,increasing coal consumption will decrease energy efficiency,but increase oil and electric power can improve efficiency obviously. The paper suggests to develop high level manufacture,Energy consumption and production should transform from fossil energy to reproducible energy,and Energy conservation mechanism by price should be established.
