Impact of dual value Chain embeddedness on carbon emission intensity

Against the background of the "dual carbon" goal and the construction of a double cycle pattern, exploring whether the embeddedness of the domestic value chain (NVC) and the embeddedness of the global value chain (GVC) can help to realize carbon emission reduction is crucial. This study calculates the dual value chain embeddedness at the provincial level in China using the input-output table and value-added decomposition model of regional embeddedness worldwide, and constructs an empirical analysis framework for the impacts of the NVC and GVC on carbon emission intensity. Results from this study reveal the following: (1) Baseline regression analysis shows that NVC and GVC embedding has a significant inhibitory effect on carbon emissions intensity. After robustness tests such as replacing the explanatory variables, excluding samples, and lagging one period, the conclusion still holds. (2) Moderating effect analysis demonstrates that the interaction effect of NVC and GVC embedding can significantly enhance the inhibitory effect of both on carbon emissions intensity. We conclude that china should maximize the utilization of available comparative advantages, coordinate the two markets at home and abroad, strengthen the benign interactions between the GVC and NVC, unleash their potential of the GVC and NVC for economic development and environmental improvement.
