【摘要】 新发展阶段下，我国面临人口老龄化和碳中和的双重压力，科学认识人口老龄化与碳排放的关系具有重要意义。本文基于30个省、市、自治区的数据，建立门限—STIRPAT扩展模型，就人口老龄化对碳排放的影响，以及该影响是否随消费变动呈现阶段性特征进行分析。结果表明，我国人口老龄化对碳排放的影响存在地区差异。在全国和东部地区，老龄化受居民消费双重门限的影响，均能产生显著的碳减排效应；而在中西部地区仅存在单一门限效应，且老龄化对碳排放的抑制作用并不明显。更多还原

【Abstract】 As global climate change intensifies, China has pledged to become carbon neutral, meanwhile, China has entered a critical moment of an aging society. Facing the dual pressure, it is ofgreat significance to scientifically understand the relationship between aging and carbon emission. Thus, this paper aims to study whether population aging has an impact on carbon emissions, and whether the impact will be staged with the improvement of residents’ consumption level. This paper selects panel data from 30 provinces in China and constructs an extended STIRPAT-threshold model for analysis. The results show that there are regional differences in the impact of aging on carbon emission in China.And the aging in the eastern region can produce significant carbon emission reduction0 effect under the dual threshold of residents’ consumption. There is only a single threshold effect in the central and western regions, but the inhibitory effect of aging on carbon emissions is not obvious.更多还原
