Assessment on the Decoupling Between Industrial Development and Energy Consumption in Beijing-Tianjin-Hebei Region

Based on the decoupling indicators of economic driving force, pressure of energy consumption and energy consumption efficiency, this paper constructs a system for evaluating the decoupling between industrial development and energy consumption in Beijing-Tianjin-Hebei region, and analyzes the decoupling situation of industrial development and energy consumption in Beijing-Tianjin-Hebei region from 1997 to 2016 by using elastic analysis method. Results show that: due to the superimposed effect of three regions, there is a change trend of “expansive negative decoupling – strong decoupling – weak decoupling” between the development of the primary industry and its energy consumption in Beijing-Tianjin-Hebei region; there is a change trend of “weak decoupling – expansive negative decoupling – weak decoupling – strong decoupling” between the development of the secondary industry and its energy consumption in Beijing-Tianjin-Hebei region; there is a change trend of “increasing connecting – weak decoupling” between the development of the tertiary industry and its energy consumption in Beijing-Tianjin-Hebei region.
