Structural evolutionary analysis of the embodied net carbon transfer network of Belt and Road trade: from the regional and sectoral perspectives.

The countries along the "Belt and Road" (B&R) have close cooperative connections economically and in trade, and these connections lead to a large amount of embodied carbon emissions and have formed a complex network of net carbon transfers. Considering 63 countries and 26 sectors, this study uses the Eora multiregional input-output (MRIO) model to construct the embodied carbon transfer networks in 1992, 1998, 2004, 2010, and 2016. Additionally, it applies the social network approach to analyze the structural characteristics and evolution of carbon flow networks in the countries and regions along the B&R.
