中国制造业碳排放强度变动及其因素分解

目前,中国已成为世界制造大国,并且制造业的碳排放量已占全国碳排放总量的80%以上,要寻找制造业的有效减排途径,就需要准确分析和计量促使制造业碳排放增加的影响因素.为此,本文在对我国制造业碳排放强度变化趋势进行分析的基础上,运用因素分解法将碳排放强度变化分解为结构份额与效率份额,并基于1996-2007年的统计数据对我国制造业碳排放强度变化中的结构份额和效率份额进行了测算.结果表明,我国制造业碳排放强度在1996-2007年间整体呈现出下降的趋势,我国制造业碳排放强度的下降均是由效率引起的,而结构则引起了碳排放强度的提升.因此,应大力推进低碳技术的开发,以进一步发挥效率份额在制造韭碳排放强度下降的积极作用,同时,进一步优化制造韭产业结构,逐步淘汰一些高碳排放行业,使制造业产业结构向规模化、低碳化和高端化升级.

On the Changes in the Carbon Emission Intensity of China' s Manufacturing Industry and Its Factors Decomposition

At present,China has become the world manufacturing country and carbon emissions in the manufacturing sector accounts for the national carbon emissions more than 80%,to search for an effective route of emissions reduction in the manufacturing industry,it will need to analyze and measure the factors which promote the increase of carbon emissions in manufacturing industry.Thus this paper,analyzes the changes in the carbon emission intensity of China's manufacturing industry firstly,and on basis of it,calculat...
