Abstract

Population migration is a key driver in reshaping the geospatial pattern of energy consumption and associated carbon emissions. However, the extent of shifts in the geospatial pattern and their primary drivers have not yet been quantitatively validated. We develop an integrated system and a novel structural decomposition analysis (SDA) method and for estimating the residential carbon emissions flows embedded in interprovincial population migration in China from 2010 to 2020. Interestingly, despite the significant increase in the scale of population migration between Chinese provinces (79.94 to 122.83 million), the net increase in carbon emissions due to population migration is decreasing (+23.42 to +5.16 Mt CO₂). Lots of rural-urban migration flows from inland to coastal areas shift from increasing carbon emissions in 2010 to decreasing carbon emissions in 2020. The SDA indicates that the primary driver behind the decline in residential carbon emissions can be attributed to urbanization (-20.82 Mt CO₂). Overall, this study can inform other developing countries on sustainable urbanization and geospatial management for energy decarbonization.

中国人口迁移中的居住碳排放流：地理空间动力学分析

人口迁移是重塑能源消耗和相关碳排放地理空间格局的关键驱动因素。然而，地理空间格局的变化程度及其主要驱动因素尚未得到定量验证。我们开发了一个综合系统和一种新颖的结构分解分析（SDA）方法，用于估算 2010 年至 2020 年中国省际人口迁移中蕴含的居住碳排放流。有趣的是，尽管中国省际人口迁移规模大幅增加（从 7994 万增加到 12283 万），但人口迁移导致的碳排放净增加量却在减少（从 +2342 万吨二氧化碳减少到 +516 万吨二氧化碳）。大量从内陆地区向沿海地区的城乡人口迁移从 2010 年的碳排放增加转变为 2020 年的碳排放减少。SDA 表明，居民碳排放量下降的主要原因是城市化（-2082 万吨二氧化碳）。总之，这项研究可以为其他发展中国家的可持续城市化和能源去碳化的地理空间管理提供参考。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
