Abstract
The concurrent acceleration of digitalization and urgent carbon reduction goals makes it critical to understand the spatial relationship between digital technology spillover and cross-regional carbon transfers. To this end, we investigate how interprovincial digital technology spillovers affect carbon transfers across China's economic sectors. Using a multi-regional input-output model for 31 Chinese provinces, we identify strong spatial correlations between sectoral carbon transfers and regional digital technology spillovers. We find that this relationship hinges on eco-friendly product development, market-aligned innovation, and sector-wide industrial transformations within their respective sectors. These findings provide policymakers with actionable, sector-specific insights for harnessing digitalization to mitigate carbon emissions, thereby advancing sustainable development and the pursuit of carbon equity.
