Research on Efficiency of Industrial Energy Conservation and Emission Reduction of Dalian Based on DEA Model

Based on DEA model, this paper makes pillar industry of Dalian as basic unit to evaluate the efficiency of energy conservation and emission reduction, establishes evaluation index system of energy conservation and emissions reduction from two aspects of input and output, and builds Dalian industrial efficiency evaluation model of energy conservation and emission reduction. Analysis shows that the initial success of energy conservation and emissions reduction works in Dalian, but chemical raw materials and chemical products manufacturing, agricultural food processing industry are in the overall inefficient state, which have great potential for saving energy and reducing consumption.
