【摘要】：科学识别我国各省区碳足迹及省际间碳转移特点,对于促进全国统一碳市场的建立和运行具有重要意义.基于MRIO模型,自主编制了包括12个省级区域、14个行业的2007年中国区域间投入产出表,测算了这12个省级区域的碳足迹特点和省际间碳转移情况.结果显示:由于经济发展水平、产业结构、能源结构、工业化程度和人口等因素的不同,各省碳足迹特点呈现较大差异;我国存在由能源资源丰富地区和重化工业密集省份向经济发达地区和资源短缺省份的碳转移现象,其中,河北、山西和内蒙古三省对外省区呈现碳净调出态势且调出量较大;省际间距离越近,产业结构互补性越强,则省际间的碳转移规模也就越大.当前,我国应加快推进能源结构调整和产业升级转型;强化区域内省际之间的相互协作,降低碳减排成本;在未来全国碳排放权交易体系下,应综合考虑各省的碳足迹水平和省区间碳转移情况,科学界定各省区的碳排放责任,公平合理地分配碳排放配额,以促进我国碳市场的顺利运行.
[Abstract]:It is of great significance to identify the carbon footprint and the characteristics of inter-provincial carbon transfer between provinces and regions in China scientifically to promote the establishment and operation of a unified national carbon market. Based on MRIO model, the input-output table of China in 2007, which includes 12 provincial regions and 14 industries, is compiled, and the characteristics of carbon footprint and inter-provincial carbon transfer among these 12 provincial regions are calculated. The results show that the characteristics of carbon footprint of different provinces are different due to the different factors such as economic development level, industrial structure, energy structure, industrialization degree and population. There is a phenomenon of carbon transfer from energy-rich areas and heavy industrial intensive provinces to economically developed areas and resource-short provinces. Among them, Hebei, Shanxi and Inner Mongolia provinces present a net carbon transfer situation and the amount of output is relatively large. The closer the inter-provincial distance, the more complementary the industrial structure, the larger the scale of inter-provincial carbon transfer. At present, China should speed up the energy restructuring and industrial upgrading transformation; strengthen the inter-provincial cooperation within the region, reduce the cost of carbon reduction; in the future of the national carbon emissions trading system, In order to promote the smooth operation of China's carbon market, it is necessary to comprehensively consider the level of carbon footprint and the situation of carbon transfer between provinces and regions, scientifically define the responsibilities of carbon emissions in each province, and allocate carbon emission quotas fairly and reasonably in order to promote the smooth operation of the carbon market in China.
