我国政府已明确“截止2015年末,我国单位国内生产总值二氧化碳排放(碳强度)要比2010年下降17%”的减排目标,而目前学术界缺乏将国家制定的碳强度约束指标进行省级分解的系统考量。因此,制定科学的碳强度约束指标分配体系是亟须解决的现实问题。本文提出基于“零和收益”思想的环境生产技术(ZSG环境生产技术)的碳排放分配模型,将“十二·五”时期省级碳强度约束指标进行效率分配。研究结果表明,使用ZSG环境生产技术模型对碳排放进行效率分配后,各省区的投入—产出指标同时处于ZSG前沿面上,实现经济指标、能源指标和环境指标的整体帕累托最优;“十二·五”时期各省区的碳强度约束指标大相径庭,部分省区未来需要下降的幅度超过17%的国家平均标准,面临形势较为严峻的低碳转型之路。
Our government has made it clear that “as of the end of 2015, China’s carbon dioxide emissions per unit of GDP (carbon intensity) than the 17% reduction in 2010,” the emission reduction targets, and the current academic lack of carbon intensity constraints set by the state indicators Systematic consideration of provincial decomposition. Therefore, to formulate a scientific carbon intensity constraint indicator distribution system is an urgent problem to be solved. In this paper, a carbon emission allocation model of environmental production technology (ZSG environmental production technology) based on the idea of “zero and yield ” is proposed to allocate provincial carbon intensity constraint indicators during the “12.5 ” period. The results show that after the efficiency allocation of carbon emissions using the ZSG model, the input-output indicators of all provinces and autonomous regions are simultaneously on the front of the ZSG, achieving the overall Pareto optimality of economic indicators, energy indicators and environmental indicators. In the “12th Five-Year Plan” period, the targets of carbon intensity constraint in provinces and autonomous regions are very different. Some provinces and autonomous regions need to have the national standard of decline exceeding 17% in the future and face a severe carbon transition.
