摘要
采用脱钩模型和分解模型对1998—2020年中国工业CO_(2)排放与经济发展的脱钩关系进行解析。研究发现:1998—2020年我国工业CO_(2)排放与经济发展间呈现负脱钩状态,但是负脱钩程度在减弱,工业CO_(2)排放与经济发展的关系在向协调发展的方向改善。脱钩稳定性方面,工业CO_(2)排放与经济发展的脱钩状态波动较大,但是稳定性程度在逐步提升。从脱钩因素方面分析,1998—2020年,电力脱钩弹性(EL)、工业电气化脱钩弹性(LS)、价值创造脱钩弹性(SG)均对总脱钩弹性(CG)产生了积极影响,但是能耗脱钩弹性(CE)还未对总脱钩弹性(CG)产生正向贡献。
This paper uses the decoupling model and decomposition model to analyze the decoupling relationship between China’s industrial CO_(2) emissions and economic development from 1998 to 2020.The study found that from 1998 to 2020,our country’s industrial CO_(2) emissions and economic development showed a state of negative decoupling,but the degree of negative decoupling was weakening,and the relationship between industrial CO_(2) emissions and economic development was improving in the direction of coordinated development.In terms of decoupling stability,the decoupling state of industrial CO_(2) emissions and economic development fluctuates greatly,but the degree of stability is gradually improving.From the analysis of decoupling factors,during 1998-2020,electricity decoupling elasticity(EL),industrial electrification decoupling elasticity(LS),and value creation decoupling elasticity(SG)all had a positive impact on the total decoupling elasticity(CG),but energy consumption Decoupling elasticity(CE)has not yet made a positive contribution to the total decoupling elasticity(CG).
