Study on the Correlation Analysis of Energy Consumption in Economic Industries and Evaluation of Carbon Emission Decoupling in Beijing-Tianjin-Hebei Region

Abstract

A deep exploration of the correlation analysis of energy consumption in economic industries and evaluation of carbon emission decoupling in Beijing-Tianjin-Hebei region can provide important reference for its government departments in decision-making to accelerate the formulation and improvement of energy consumption control policies and systems. In this paper, by use of the grey incidence analysis, the correlation analysis model of energy consumption and economic growth in the economic industries of Beijing-Tianjin-Hebei region was built to analyse the correlation characteristics of industrial energy consumption and economic growth in BeijingTianjin-Hebei region. Meanwhile, based on the indexes of economic output value and carbon emission efficiency in Beijing-Tianjin-Hebei region, a carbon emission increment model was set up to measure the contributions of carbon emission structure increment and efficiency increment in the region. And the Tapio elastic coefficient method was adopted to identify the decoupling trend of carbon emissions in Beijing-TianjinHebei region. Finally, the corresponding countermeasures and suggestions were put forward to provide support for the government departments of Beijing-Tianjin-Hebei region to accelerate the formulation and improvement of policies and measures for decoupling economic growth from energy consumption and carbon emissions in the economic industries of this region.
