随着市场化与城镇化水平的不断提高,我国的经济增长模式出现了阶段性的变化,这种变化必然会引致碳排放总量出现阶段性特征,但是鲜有研究对这一特征进行探讨。为此,本文分别在全国层面与省际层面考察我国碳排放的阶段性特征,旨在对我国不同地区的节能减排策略提出有针对性的建议。研究发现,无论是在全国层面还是省际层面,我国碳排放量均存在阶段转折点,并以阶段转折点为界呈现明显两阶段性特征;东部地区阶段转折点所对应的平均碳排放水平最高,减排效率也最高,西部地区减排效率最低,而中部地区减排阻力最大。因此,当前我国应该在保证总体碳排放水平稳步下降的同时,对不同区域施行不同的减排策略。东部地区应该在减排过程中发挥示范效应,承担更多的减排义务。
With the continuous improvement of marketization and urbanization, the pattern of economic growth in our country has undergone a periodical change. This change will inevitably lead to the periodic characteristics of total carbon emissions. However, few studies have explored this feature. Therefore, this paper examines the periodic characteristics of China’s carbon emissions at the national and inter-provincial levels respectively, and aims to make targeted suggestions on energy-saving and emission reduction strategies in different regions of China. The study found that both at the national and inter-provincial levels, China’s carbon emissions are at the turning point of the stage, and the turning point of the stage shows a clear two-stage characteristic; the turning point in the eastern region corresponds to the highest level of average carbon emissions, emission reduction The highest efficiency, the lowest emission efficiency in the western region, while the central region has the largest emission reduction resistance. Therefore, at present, China should implement different emission reduction strategies in different regions while ensuring that the overall level of carbon emissions will steadily decline. The eastern region should exert a demonstration effect in the emission reduction process and assume more emission reduction obligations.
