英文摘要：

Since the difference of electric consumption among energy intensive industries, the analysis on the features of electric consumption can promote the performance of energy saving and emission reduction. This paper investigates the general characters of electricity consumption among energy-intensive industries in Tianjin based on the cointegraiion theory and panel data model. A long- term equilibrium model containing of the electricity demand, industry output and the electric power consumption per unit output value is established. Finally, the industry that electricity consuming is highly dependent on its output and power consuming intensity is found out, which will contribute to policy making for energy intensive industries in the future.
