摘要: 气候变化日益严重,分析碳排放的影响因素,探讨工业碳减排意义重大。运用对数平均权重分解法(LMDI)的加和分解法建立了能源消耗碳排放的因素分解模型,从能源强度、产业结构、能源结构、经济产出和从业人口规模等5个方面对安徽省规模以上工业行业的碳排放进行实证分析。结果显示:能源强度、产业结构对碳排放有着较强的负效应,经济产出、从业人口规模有强的正效应,能源结构表现出不显著的正效应。安徽工业行业中,电力、热力生产和供应业,煤炭开采和洗选业,石油加工、炼焦和核燃料加工业,黑色金属冶炼和压延加工业及非金属矿物制品业这五大高能源强度是影响安徽省工业碳排放的最主要行业。为降低碳排放,有针对性地提出了降低能源强度,调整产业结构及减少五大行业的比重的政策建议。图4表5参14

Abstract: Climate change is increasingly serious, and analysing the determinants of carbon emissions and studying carbon emission reduction is significant. The research used additive decomposition method of LDMI to build a factor decomposition model of carbon emissions from the energy consumption and conducted an empirical analysis of above scale industrial industries from five aspects including energy intensity, industrial structure, energy structure, economic output and the employed population scale. The results revealed that energy intensity and industrial structure had significant negative effects on carbon emissions; while economic output and the employed population scale had strong positive effects; energy structure had no significant negative effect on carbon emissions. Of the industrial industries in Anhui, electricity and heat production and supply industry, coal mining and dressing industry, petroleum processing, coking and nuclear fuel processing industry, ferrous metal smelting and rolling processing industry, non-metallic mineral products industry were the main industries affecting industrial carbon emissions. To reduce carbon emissions, policy suggestions on, reducing energy intensity, adjusting industrial structure and reducing the proportion of five industries were proposed. [Ch, 4 fig. 5 tab. 14 ref.]-
