摘要
通过对1999—2010年河南省工业行业能源消耗碳排放行业差异的分析,发现工业直接碳排放量呈逐年增加趋势,并没有随着经济发展而实现碳排放的"脱钩";采矿业能源消耗的直接碳排放量逐渐增长,已成为工业直接碳排放量快速增加的重要驱动行业,制造业和电力—燃气—水的生产和供应业直接碳排放的速度有减缓的趋势;工业行业间直接碳排放存在明显差异性,可以划分为直接碳排放量和直接碳排放强度都较高的高碳行业、直接碳排放量较大和直接碳排放强度较低的中碳行业、直接碳排放量和直接碳排放强度都较小的低碳行业以及直接碳排放量较小、直接碳排放强度较高的碳排放关注行业4种类型,并且河南省具有专业化优势和比较优势的行业大多集中在高碳部门。利用投入产出模型,计算了工业分行业的间接碳排放,发现产业部门关联效应所引发的间接碳排放不容忽视,并且在一些行业中占有较高比重。针对工业内部碳排放的行业差异性,应有效协调工业化进程与节能减排的关系,针对行业特性来制定减排政策。
By analyzing the sectoral difference in carbon emission of industrial energy consumption during 1999-2010 in Henan province, we have found that： （1） The total amount of industrial direct carbon emission showed a gradual increase, and did not achieve ＂decoupling＂ with economic development; （2） The total amount of direct carbon emission of energy consumption in mining industry increased annually, and has become an important driver of the rapid increase in industrial direct carbon emission, on the contrary, the total amount of direct carbon emission in manufacturing sector and the production and distribution of electricity, gas and water was slowing down; （3） Direct carbon emission was significantly different among various industrial sectors, which can be accordingly divided into four types： high-carbon sectors with high total amount of direct carbon emission and direct carbon intensity, medium-carbon sectors with high total amount of direct carbon emission and low direct carbon intensity, low-carbon sectors with low total amount of direct carbon emission and direct carbon intensity, and carbon emission sensitive sectors with low total amount of direct carbon emission and high direct carbon intensity. Most sectors with development advantages in Henan Province were high-carbon sectors. （4）Based on Input-output Model, we calculated the indirect carbon emission of the industrial sectors. Carbon emissions reduction policies need to focus on the impact of indirect carbon emission. （5）With reference to the carbon emission difference of various industrial sectors, it is necessary to make sector-specific and sector-different emission reduction policies, and to coordinate the relationship between industrialization and energy consumption.
