Abstract
Digital technology has been gradually integrated into global production division of labor systems as a new key production factor. In the context of promoting green development, digital global value chains (GVCs) may become a new driving force to achieve emission reduction targets. In this paper, the World Input–Output Tables and logarithmic mean Divisia index (LMDI) are used to construct the measurement and decomposition framework of the digital GVC, and the corresponding emission reduction effect and mechanism of action are analyzed. The findings indicate that, first, the change in the proportion of the digital GVC added value in the digital economic added value of various departments is the most important factor influencing changes in digital GVC embeddedness. Second, the emission reduction effect of digital GVCs is significant. Third, the mechanism of the emission reduction effect of the digital GVC lies in the negative population size effect associated with digital GVC embedding being greater than the positive economic growth effect and rebound effect, thus inhibiting the growth of greenhouse emissions. This study provides empirical support for understanding the development and evolutionary characteristics of digital GVCs in individual countries (or regions) and promoting the establishment of corresponding greenhouse gas emission reduction mechanisms.
