| In recent decades,with the rapid development of China’s economy,problems such as resources and the environment have become increasingly prominent.Achieving carbon peaking and carbon neutrality is an key initiatives to achieve high-quality economic development,and emission reduction has become my country’s goal of achieving carbon neutrality.important grip.Combining with requirements of the National Development and Reform Commission and other five departments jointly issued "Energy Efficiency Benchmark Level and Benchmark Level in Key Fields of High Energy-consuming Industries(2021 Edition)",it is particularly important to clarify the emission reduction benchmark level of each region and industry and the emission reduction space when the benchmark level is reached.Based on this,this paper firstly establishes two perspectives and four dimensions(supply-side perspective-energy-saving mode and energy substitution mode;demand-side perspective-industrial transfer mode and demand structure upgrading mode)based on the basic input-output model.Emission reduction model;then,based on the above four models,four dimensions and three levels(national,provincial,and industry emission reduction potentials were calculated;finally,based on the calculation results,the national overall,provincial,and industry three levels were calculated respectively.Make corresponding policy recommendations.The study found that: at the national overall level,among the four emission reduction modes,the energy-saving mode has the most significant emission reduction effect,with an emission reduction potential of 84.20%,indicating that developing technologies to improve energy efficiency is still the primary measure to achieve carbon neutrality;energy Although the emission reduction potential of the alternative mode is smaller than that of the energy-saving mode,with the development and utilization of renewable energy in the future,the emission reduction effect will increase or even surpass the energy-saving mode;the emission reduction potential of the industrial transfer mode is compared with the previous two modes.Small,the emission reduction potential brought about by industrial transfer of RMB 1 million in the short term is 0.22%,and the economic relationship between medium and long-term regions will also weaken the emission reduction effect;the emission reduction potential under the final demand structure upgrade model It should not be underestimated,and optimizing the final demand structure through various provinces can bring about 34.80% of the emission reduction space.At the provincial level,for the central and western regions with backward technology,increasing investment in technological upgrading is the best choice for emission reduction;for industrial heavy-duty regions with heavy industry as the main production products,promoting the energy structure Reform may be a more effective means of reducing emissions;for the eastern region,the focus should be on optimizing the industrial structure,and the optimization and upgrading of the industrial structure in the eastern region can be promoted by removing excess capacity and transferring some high-carbon emission industries.At the industry level,the industries with large space for emission reduction are mainly energy-intensive industries with high carbon emission intensity.These industries include coal mining and processing products,oil and natural gas mining products,metal ore mining and processing products,non-metallic ores and other ore mining and processing products,metal smelting and rolling products,production and supply of electricity and heat,transportation,warehousing and Post,petroleum,coking products and nuclear fuel processing products,metal products,non-metal mineral products.To sum up,this paper systematically studies my country’s emission reduction potential and mode,establishes a long-term comprehensive emission reduction mechanism,and provides a scientific basis for formulating emission reduction measures and policy formulations that meet the conditions of each region. |
