摘要
煤炭资源是中国的主要能源。分析和评价煤炭资源在各行业的消费效率,对认识并改变中国能源效率现状有重要意义。本文根据能源系统的特点,构建了以煤炭消费总量、人力资源投入量和固定资产投资为投入指标以及以工业增加值为产出指标的煤炭消费效率评价指标体系,结合层次分析法建立期望产出的DEA/AHP消费效率评价模型。结合相关数据,对中国主要行业的煤炭资源效率进行了实证分析。结果表明,工业行业消费效率在众多行业中最低,主要是工业行业高耗能生产结构所致。通过实证研究发现,评价模型在理论研究方面可以有效应用于煤炭消费效率的评价,并为中国实现节能减排目标、制定相关政策和措施提供了决策支持。
It is of great significance to evaluate the coal consumption efficiency in each sectors as coal is China＇s major energy resource,which can change the status of energy consumption.This paper,according to gross coal consumption volumes,human resources and fixed assets as an input,and industrial-added values as output,constructs an index system to evaluate the coal consumption efficiency,and sets up a DEA/AHP model.Case studies show a lowest consumption efficiency in industrial sectors due to its highly-energy-consuming structure.This evaluation model can be effectively applied to evaluate the coal consumption efficiency and provides reference for making policies in reaching energy-saving and emission-reducing objectives.
