【摘要】 实现低碳经济发展目标不仅依赖于节能减排技术的提高,而且需要调整需求结构。使用基于投入产出分析法的最终需求拉动CO2排放的弹性系数指标,从前向关联和后向关联结合的视角,构建一个基于碳减排的关键部门识别模型。研究表明,根据总影响和分布影响两个指标将中国29个部门分为4类,即关键部门、本部门需求视角的相关部门、其他部门需求视角的相关部门和不相关部门,不同类别的部门最终需求对CO2排放的影响程度有显著差异且作用机制不同,必须区分行业特点有针对性地设计节能减排政策。更多还原

【Abstract】 Low carbon economic development depends not only on the advancement of emission reduction technology but also on the adjustment of demand structure.A model is built to recognize key sectors in China’s CO 2 emissions based on the final demand elasticity of all sectors using non-competitive input-output analysis,which indicator is first used in such fields.The empirical results show that all 29 sectors are classified into four categories according to total impact and distribution impact" Key Sectors "," Relevant sectors from the perspective of their final demand "," Relevant sectors from the perspective of the demand of other sectors " and " Non-relevant sectors ".It is necessary to formulate emission reduction policies according to the different roles of productive sectors.更多还原
