湖南矿业碳绩效影响因素研究

Factors Influencing Carbon Performance of Hunan′s Mining Sectors

基于湖南国民经济核算最新统计数据,分析了湖南矿业碳排放特征,构建了其碳绩效模型。研究显示,2010—2020年湖南矿业碳绩效整体水平较低,细分行业之间的碳绩效差异较大。资产规模和能源效率因素对碳绩效有正向积极影响;资产负债率及能源结构因素对碳绩效有负向制约影响;经济规模扩大、能源利用效率提升、能源结构优化及资产负债率相对稳定,促使有色金属行业、燃气生产和供应业的碳绩效水平位居前列;煤炭开采和洗选业经济规模日益递减、重煤的能源结构及能源效率低导致其碳绩效垫底。建议湖南矿业企业优化能源结构、发展低碳创新技术、提高资源利用效率,从而提升湖南矿业碳绩效。

In order to understand carbon performance of the mining sector in Hunan Province,the carbon emissions and carbon performance of the mining sector in Hunan Province were calculated based on the latest statistical data of national economic accounting,and factors influencing carbon performance were analyzed based on the established model.It is shown that the carbon performance of Hunan′s mining sector was at a relatively low level from 2010 to 2020,and there was great difference in carbon performance of sub⁃sectors.Factors of asset size and energy efficiency had a positive impact on carbon performance,while factors of asset liability ratio and energy structure had negative constraints on carbon performance.Achieving economies of scale,improving energy efficiency,optimizing energy structure and maintaining a stable liabilities⁃to⁃assets ratio made sub⁃sectors of non⁃ferrous metal and gas production and supply in the front rank in terms of carbon performance.However,decreasing returns of scale in sub⁃sectors of coal mining and washing,as well as unreasonable energy structure and low energy efficiency in coal sub⁃sector led to the carbon performance of coal sub⁃sector ranking at the bottom.Consequently,it is suggested that the mining sector in Hunan Province should optimize its energy structure,accelerate low⁃carbon innovation,and increase various energy efficiency,so as to improve their carbon performance.
