Abstract

Scientific assessment of industrial carbon emissions in the Yellow River Basin and identification of its influencing factors are of great importance for promoting green transformation, ecological protection, and high-quality development of the Yellow River Basin. Considering nine provinces in the Yellow River Basin as the research objects; using relevant data on industrial development and energy consumption in the Yellow River Basin from 2000 to 2019; and with the help of IPCC carbon emission measurement, spatial autocorrelation, and LMDI decomposition, the spatial and temporal evolution characteristics and influencing factors of carbon emissions from industries and industrial sectors in the Yellow River Basin were analyzed. Reasonable suggestions were put forward for reducing the carbon emissions from industries in the Yellow River Basin. The results showed that: ① From 2000 to 2019, industrial carbon emissions in the Yellow River Basin showed a fluctuating growth trend, with a decreasing growth rate. The spatial pattern changed from "low in the upstream and high in the middle and downstream" to "high and low value distribution," and the spatial difference gradually expanded. ② The high carbon industry was the most important source of industrial carbon emissions in the Yellow River Basin, accounting for 96.35% of the carbon emissions between the industries with a continuous growth trend, which was a significant difference. The middle and low carbon industry carbon emissions and the total proportion was low, showing different fluctuations; nine provinces and nine industrial industries had significant spatial variability. ③ Energy structure intensity, economic scale, and population scale promoted the increase in industrial carbon emissions in the Yellow River Basin and energy consumption intensity had an inhibitory effect on the increase in carbon emissions. The economic scale effect was positive and significant, which offset the negative effect of energy consumption intensity. Spatial variability was observed in the contribution value of the influence effect of the factors affecting the carbon emissions of the industry in nine provinces.

[黄河流域工业碳排放时空演变特征及影响因素]。
科学评估黄河流域工业碳排放及其影响因素,对于推动黄河流域绿色转型、生态保护和高质量发展具有重要意义。以黄河流域九省为研究对象,利用2000-2019年黄河流域工业发展和能源消费的相关数据,借助IPCC碳排放计量、空间自相关、LMDI分解等方法,分析了黄河流域工业及工业部门碳排放的时空演变特征和影响因素。提出了减少黄河流域工业碳排放的合理建议。结果表明:①2000-2019年,黄河流域工业碳排放量呈波动增长趋势,增速呈下降趋势。空间格局由 "上游低、中下游高 "转变为 "高低值分布",空间差异逐渐扩大。高碳行业是黄河流域工业碳排放的最主要来源,占行业间碳排放量的 96.35%,且呈持续增长趋势,差异显著。中低碳工业碳排放量和总量占比较低,呈现不同的波动性;九个省份和九个工业行业的碳排放量具有显著的空间差异性。能源结构强度、经济规模和人口规模促进了黄河流域工业碳排放的增加,能源消费强度对碳排放的增加有抑制作用。经济规模效应为正且显著,抵消了能源消耗强度的负效应。九省工业碳排放影响因素的贡献值存在空间差异。
