In the context of low-carbon economic development, carbon productivity has effectively integrated the two major objectives of carbon reduction and economic growth, and increasing carbon productivity has become the main approach to address global climate change. Using data from China's input-output table for 2002-2017, this study measures the evolutionary characteristics and influencing factors of carbon productivity from the perspective of embodied carbon emission in China's industrial sector. The results indicate that, first, China's industrial sectors' carbon productivity shows an increasing trend from 25.22 to 65.3 million yuan/10,000 tons of CO in 2002-2017, but the overall level is low. The energy efficiency factor is a major element affecting improvement in carbon productivity. Second, the carbon productivity of the 28 industrial sectors shows an increasing trend. There is a significant gap in the carbon productivity between different industrial sectors. The energy efficiency factor in all industrial sectors is positive, indicating that energy efficiency is a positive factor in increasing carbon productivity. Third, from largest to smallest in the carbon productivity are the primary, tertiary, and secondary industries. Finally, this paper recommends several approaches to improve carbon productivity from the perspectives of technology, differentiated policies of carbon emission reduction, and industrial structure adjustment.
在低碳经济发展背景下,碳生产率有效融合了碳减排和经济增长两大目标,提高碳生产率成为应对全球气候变化的主要途径。本文利用中国 2002-2017 年投入产出表数据,从中国工业部门隐含碳排放视角测度碳生产率的演进特征及其影响因素。结果表明:第一,中国工业部门碳生产率由 2002-2017 年的 25.22 万元/万吨 CO2增长至 65.3 万元/万吨 CO2,但整体水平仍较低,能源效率因子是影响碳生产率提升的主要因素。第二,28 个工业部门碳生产率均呈增长趋势,但不同工业部门间碳生产率存在较大差距,各工业部门能源效率因子均为正,表明能源效率是提高碳生产率的积极因素。第三,从碳生产率由大到小依次为采矿业、制造业、电力、热力、燃气及水生产和供应业、建筑业、批发和零售业、交通运输、仓储和邮政业、金融业、住宿和餐饮业、信息传输、软件和信息技术服务业、农、林、牧、渔业、其他服务业、租赁和商务服务业、科学研究和技术服务业、文化、体育和娱乐业、教育、卫生和社会工作、居民服务、修理和其他服务业、水利、环境和公共设施管理业、制造业中的化学原料及化学制品制造业、制造业中的黑色金属冶炼及压延加工业、制造业中的非金属矿物制品业、制造业中的有色金属冶炼及压延加工业。第四,从碳生产率水平由高到低依次为制造业、电力、热力、燃气及水生产和供应业、采矿业、建筑业、批发和零售业、交通运输、仓储和邮政业、其他服务业、住宿和餐饮业、农、林、牧、渔业、金融业、信息传输、软件和信息技术服务业、科学研究和技术服务业、文化、体育和娱乐业、水利、环境和公共设施管理业、租赁和商务服务业、居民服务、修理和其他服务业、卫生和社会工作、教育。最后,本文从技术、差异化碳减排政策和产业结构调整等方面提出了提高碳生产率的建议。
