%X Industry is the main source of resource consumption and environmental emissions of China,and the analyzing of eco-efficiencies for industrial sectors may provide essential information for the restructure of industrial system and the improvement of environmental quality of China.The industry composition was analyzed and the relationship between the industry and its environment was established.The energy consumption and the main environmental emissions such as wastewater,solid waste,industry SO2,smog,dust were chosen as the environmental impact categories,the corresponding eco-efficiencies of industry were defined and estimated for China in 2007.The results are as follows:the energy efficiency is 615.5×104 yuan·ktce-1,the wastewater and solid waste related eco-efficiencies are 54.3×104 yuan·kt-1 and 1.9×104 yuan·t-1,respectively;industry SO2,smog,dust related eco-efficiencies are 59.6×104, 169.2×104 and 184.6 ×104 yuan·t-1,respectively.The eco-efficiencies of 39 industry sectors were analyzed extensively and the results showed that,the distribution of industrial sectors in above eco-efficiencies is uneven,and the order of industrial sector in industry will vary with industry sector and eco-efficiency category.Meanwhile,for the same category of eco-efficiency,the values for different industry sectors may change from centuplicate to several thousand folds,therefore a great possibility for the improvement of industry eco-efficiency is exist in the restructure of industry system.
