摘要
以中国人口生育政策调整为研究背景,基于STIRPAT模型和Leslie模型综合考察中国人口生育政策调整可能对实现“我国二氧化碳排放力争2030年前达到峰值”目标所带来的影响。结果表明,除了经济发展水平、能源技术水平、能源消费结构等因素外,人口年龄结构对人均碳排放也具有显著影响。在论文设置的四种生育率情景下,人口总量峰值分别出现在2025年、2027年、2031年和2027年。若生育政策调整能够有效提高社会总和生育率,人口规模和人口年龄结构的变化会使碳排放总量峰值推后出现。因此,中国逐步放宽的人口生育政策可能会给实现碳达峰目标带来一定压力。
China’s population policy has been frequently adjusted.Hence,using extended STIRPAT theoretical model and a Leslie model,we comprehensively examine the impact of population policy adjustment on China’s total carbon emission peak.The results show that in addition to economic development level,energy technology level and energy consumption structure,demographic structure also has a significant impact on per capita carbon emissions.Under the four fertility scenarios used in this paper,population peak will be achieved in 2025,2027,2031 and 2027.If the birth policy changes can effectively increase the actual fertility rate,then the changes in the population size and age structure will also achieve the peak of total carbon emissions delayed by one to three years.Therefore,China’s gradual relaxation of the population policy at present may bring pressure on the commitment of the achievement of the carbon emission peak before 2030.
