1270 | 856 | Quantifying land flow embodied in interregional trade and its repercussions for carbon emissions in China | Shengfu Yang
The interregional flow of land embodied in remote linkages exerts a significant impact on land use and carbon emission transfer patterns among regions, underscoring the importance of investigating this process for sustainable land utilization. Based on a multiregional input‒output model, this study quantifies the embodied land flow and its repercussions for carbon emissions in China, analyzes the corresponding spatial distribution and differences, and further clarifies the characteristics of embodied land flow by constructing the contribution and dependency index. The results show that more economically developed regions occupy land in less developed regions through embodied land flow, and there are differences in the flow of various land types among regions due to disparities in regional endowments. For example, embodied construction land has primarily moved to economically developed eastern China. The transfer pattern of carbon emissions from land use caused by embodied land flows presents a spatial inconsistency. The developed coastal provinces of Guangdong, Jiangsu, Zhejiang and Shanghai all transfer more than 10 million tons of carbon emissions to other regions. The average levels of contributions to and dependence on embodied land flows in Chinese provinces were 20.51% and 23.13% in 2012, and these values rose to 27.14% and 27.23% in 2017, respectively, indicating a strengthening of interregional land system linkages and an intensification of land supply and demand. Furthermore, the embodied land flow and its associated carbon emission transfer can be assessed to ascertain the entities responsible for land consumption and carbon emissions. This underscores the significance of examining the interplay between land use and carbon emissions in shaping sustainable development pathways.
