摘要
以投入产出分析表和生命周期评价(EIO-LCA)模型为基础,结合IPCC的清单方法,分别构建中国2007年和2012年的碳排放矩阵,对生产满足国民经济最终消费的产品服务量所需要的直接或间接碳排放量进行分析。结果表明:2012年的直接碳排量较2007年明显增长,但碳排放强度却有一定程度的下降;电力行业的碳排放强度远超其他行业;我国的能源生产和消费依旧以煤炭为主;制造业的隐含碳排放量最高,但已有下降趋势,而服务业的隐含碳排量有一定幅度的上升。
Based on the input-output analysis table and the life-cycle assessment （EIO-LCA） model and the inventory method of IPCC, this paper constructs the carbon emission matrix of China in 2007 and 2012 respectively, analyzes the direct or indirect carbon emissions needed to produce services that meet the final consumption of the national economy. The results show that the direct carbon emissions in 2012 are obviously higher than that in 2007, but the intensity of carbon emission has declined to a certain extent. The carbon intensity of power industry is far higher than that of other industries. Energy production and consumption are still dominated by coal. The implied carbon emissions of the manufacturing sector are the highest, but there has been a downward trend, while the implied carbon emissions of the service industry have increased to a certain extent.
