摘要(Abstract)：

受能源消费结构的影响,煤炭作为我国经济发展的资源支柱,一方面推动着经济快速增长,另一方面也对中国节能减排、降低碳排放强度提出了挑战,因而准确认识碳排放强度与煤炭消耗之间的交互冲击作用机理,为挖掘碳减排路径提供了科学依据。本文选取1990-2008年间中国碳排放强度与煤炭消耗指标,采用EG协整检验证明碳排放强度与煤炭消耗之间存在长期稳定关系,并以此建立VAR模型和脉冲响应函数,考察碳排放强度与煤炭消耗之间的长期动态影响特征。冲击响应分析结果表明:(1)煤炭消耗比重的变化对碳排放强度的冲击影响具有一定滞后性和波动性,但冲击作用长期持久;(2)碳排放强度对煤炭消耗比重的冲击影响在短期内较剧烈,但长期冲击影响不明显;(3)煤炭消耗比重的降低在长期内会促使碳排放强度的降低,因而可以通过降低煤炭消耗比重来达到降低碳排放强度的目的。最后,从结构性降低、产业传导性降低以及技术性降低等角度,提出减少煤炭消耗、降低碳排放强度的相关对策措施。
