基于2007年和2012年投入产出表,利用投入产出技术和多因素多阶影响分析(MMIA)法对河北省碳排放强度结构进行了数量论证和分析。分析结果表明:在河北省碳排放强度的最终使用结构中,投入技术减排在总的碳排变化中起重要作用,通过改进生产技术来提高生产效率或改变投入结构对碳排总强度的减小非常关键。在总产出结构中,单位总产出能耗的下降是碳排下降的主因,而投入结构和产业结构变化对减排是不利的,尤其是结构变化的负作用非常明显。
Based on 2007 and 2012input-output tables,the paper analyzes and demonstrates the structure of carbon emissions intensity in He Bei province by using input-output technique and MMIA method.Analysis results shows that:In He Bei Province carbon emission intensity of end using structure,input technology reduction in total carbon discharge plays an important role in the change,through the improvement of production technology to improve production efficiency or change the input structure of carbon row total strength reduction is important.In the structure of total output,a total output energy consumption decline still is the main cause of carbon emission decreased,and the input structure and industrial structure change is disadvantageous for emission reduction,especially the negative effect of structural change is very obvious.
