广东省经济结构转型对协同减污降碳的影响

在经济快速发展和减污降碳的双重压力下，通过经济结构转型实现协同减污降碳，是广东省可持续发展的迫切需要. 本研究利用减排量弹性系数评估SO₂、NO_x、烟粉尘与CO₂排放量变化的协同性，基于环境投入产出模型和结构分解分析方法探究广东省经济结构转型对协同减污降碳的影响. 结果表明:①从生产端看，电力热力的生产和供应业以及非金属矿物制品业的大气污染物和CO₂排放量较大；从消费端看，建筑业同时排放了大量大气污染物和CO₂. ②2007—2017年生产结构变化和最终需求产品结构变化对减污降碳的影响存在不协同性，未来可通过优化生产结构和最终需求产品结构促进协同减污降碳. 研究显示，应以生产结构和最终需求产品结构转型为重要抓手，提高广东省减污降碳的协同性，实现高质量可持续发展. 

Impacts of Economic Structural Transition on Synergetic Control of CO2 and Air Pollutants in Guangdong Province

Under the pressures of rapid economic development and the control of CO₂ and air pollutants, the synergetic control of CO₂ and pollutants through economic structural transformation is an urgent need for the sustainable development of Guangdong Province. This study evaluates the synergy of changes in SO₂, NO_x, soot, and CO₂ emissions through the elasticity coefficient of emission reduction. Based on environmentally extended input-output model and structural decomposition analysis, we investigate the impact of economic structural transformation on the synergetic control of CO₂ and air pollutants in Guangdong Province. The results show that: (1) From the production perspective, the electricity and heat power production and supply sectors and the non-metallic product manufacturing sector are the major emitters of all air pollutants and CO₂. From the consumption perspective, the final demand of the construction sector drives lots of air pollutant and CO₂ emissions. (2) There is no good synergy between pollutant reduction and CO₂ emission mitigation effected by the changes in production structure and final demand product structure. This indicates the potential for synergetic control of CO₂ and air pollutants by optimizing production structure and final demand product structure in the future. Therefore, special attention should be paid to the transformation of production structure and final demand product structure to promote synergetic control of CO₂ and air pollutants. This can help Guangdong Province achieve high-quality and sustainable development.
