探讨了“一带一路”沿线国家隐含碳排放转移特征。为明晰“一带一路”倡议实施前后相关国家碳排放变动,以2012年、2020年世界多区域投入产出(MRIO)表为基础,构建了一个复杂的联动网络结构模型,探索了“一带一路”沿线国家隐含碳排放流动网络的结构特征。研究结果表明:“一带一路”沿线国家碳排放空间格局保持稳定状态,中国、俄罗斯、伊朗和印度稳居隐含碳排放高位;中心国家的入度指标在2012年与2020年前后有较大幅度的波动,主要集中在中国、孟加拉国、印度、沙特阿拉伯、伊拉克、以色列;整体碳转移网络呈现出明显的“核心—边缘”形态,“一带一路“沿线国家经济带北线和南线是碳排放量较大的区域,大部分国家通过与核心节点的联系向中心靠拢。

This article explores the characteristics of implicit carbon emission transfer in countries along the Belt and Road. In order toclarify the changes in carbon emissions of relevant countries before and after the implementation of the Belt and Road Initiative, a complexnetwork structure model based on the 2012 and 2020 World Multi-Regional Input-Output ( MRIO) tables is constructed. This modelinvestigates the structural characteristics of the implicit carbon emission flow network in countries along the Belt and Road. Research showsthat the spatial pattern of carbon emissions in countries along the Belt and Road remains stable, with China, Russia, Iran, and Indiaconsistently having high implicit carbon emissions. The in-degree index of central countries experienced significant fluctuations around2012 and 2020, primarily concentrated in China, Bangladesh, India, Saudi Arabia, Iraq, and Israel. The overall carbon transfer networkexhibits a clear “core-periphery” structure, where the northern and southern economic belts of countries along the Belt and Road areregions with higher carbon emissions, most countries are gradually moving closer to the core nodes through their connections.
