摘要
采用广义迪氏指数分解法对我国石化行业2000-2016年的二氧化碳排放演变进行分解,进行阶段性及累计效应分析,考察投资、产出、能源消费以及相应的碳强度、能源强度和投资效率的变化对二氧化碳排放变化的贡献情况。结果表明,投资、产出及能源消费规模是促进二氧化碳排放增长的主要因素;投资碳强度和产出碳强度是主要的促降因素;能源碳强度、投资效率和能源强度作用较弱,具有很大的改善空间,是未来石化行业减碳政策制定的主要着手点。
In this paper,the evolution of carbon dioxide emissions in China’s petrochemical industry from 2000 to 2016 is decomposed by using the generalized Divisia Index Method,and the periodic and cumulative effect analysis is carried out to investigate the contribution of changes in investment,output,energy consumption and corresponding carbon intensity,energy intensity and investment efficiency to the change of carbon dioxide emissions.The results show that:investment,output and energy consumption scale are the main factors to promote the growth of carbon dioxide emissions;investment carbon intensity and output carbon intensity are the main factors to promote the growth of carbon dioxide emissions;energy carbon intensity,investment efficiency and energy intensity play a weak role,which has a lot of room for improvement,and is the main starting point of carbon reduction policy-making in the petrochemical industry in the future.
