中国钢铁产业能源消耗、碳排放与增加值脱钩分析

his paper, by employing the method of elasticity decoupling and the Tapio decoupling index, investigates the decoupling relationship of the growth of Chinese steel industry and its energy consumption and carbon emission in the period of 2000 to 2010. In addition, based on the analysis framework of LYQ and utilizing adjusted Tapio decoupling evaluation model, it is examined that the influence of each element influencing the decoupling status between the growth and the carbon emission of Chinese steel industry. Results show that, generally, there is an outspread negative decoupling relationship among the energy consumption, carbon emission and added-value of Chinese steel industry. The decoupling elasticity of industry emission and the one of industry energy-saving have a trend of alternation and fluctuation. The decoupling elasticity of industry carbon emission and energy saving has a positive impact on the decoupling status of carbon emission and industry added-value, while the decoupling elasticity of energy-saving and added-value has a negative impact on the decoupling status of carbon emission and industrial added-value, and the carbon emission of steel industry driven by economy is relative evident.
