[Digital Economy and Carbon Productivity： Evidence from the Logistics Industry].

Low-carbon transformation is an inevitable requirement for China to transform its economic development mode in the new stage of development. As a new driving force for high-quality economic development in China， the digital economy brings new opportunities for the realization of the dual-carbon goal. Using panel data of 30 provinces， municipalities， and autonomous regions of China from 2011-2020 and input-output model logistics carbon productivity， this paper discusses the direct effect of the digital economy on logistics carbon productivity， the action path， the space correlation and space spillover effect， and the influence of the digital economy on the logistics carbon productivity of regional heterogeneity. The results show that China's digital economy had a significant "U-shaped" nonlinear influence on the logistics industry during the investigation period. The results also indicate that the digital economy affects logistics carbon productivity through labor productivity， industrial structure， and energy transition， including labor efficiency and energy transition； that it has a significant spatial spillover effect on the logistics carbon productivity； and that the influence of the digital economy on logistics carbon productivity has regional heterogeneity.
