Analysis and Optimization of Industrial Structure Based on the Relative Efficiency Index

Abstract

Based on the theory and method of eco-efficiency, the relative efficiency index (Ri) was constructed in the paper. According to the range of the relative efficiency index, the industrial sectors can be divided into four categories. When Ri≥R+0.5δ , the industry should be encouraged. When R≤Ri<R+0.5δ, the industry should be optimized and updated. When R-0.5δ≤Ri<R, the industry should be transformed and elevated. When Ri<R-0.5δ, the industry should be restricted, even eliminated. Jiaxing City in Zhejiang Province was selected to be the typical base for further analysis. The results showed that from the perspective of saving water and energy, six important industries, including Paper and paper products, Textile, Beverage Manufacturing, Chemical raw materials and chemical products manufacturing industry, should be restricted, even eliminated. From the perspective of water pollution control, twelve industries, such as Paper and paper products, Textile, Chemical materials and chemical products manufacturing industry should be restricted, even eliminated. From the perspective of air pollution control, four industries, including Paper and paper products, Chemical raw materials and chemical products manufacturing, Electricity, heat production and supply, Non-metallic mineral products industry should be restricted, even eliminated. Besides, the Paper and paper products, the Chemical raw materials and chemical products manufacturing industry theoretically were the highlight of the industries which should be restricted, even eliminated.
