Abstract

Promoting synergistic governance of pollution reduction and carbon mitigation (PRCM) constitutes a core task for China’s green transformation. As a major digital‑driven initiative, the supply‑chain digitization pilot policy (SCD) holds promise for advancing environmental governance, yet its spatial spillover effects on PRCM remain under‑explored. Using panel data of 237 Chinese cities from 2011 to 2023, this study measures urban PRCM performance and adopts a spatial Durbin model (SDM) to explore SCD’s direct and indirect impacts on PRCM, considering geographic and economic-geographic proximity. The results show PRCM has significant positive spatial autocorrelation; SCD significantly improves local PRCM and exerts positive spatial spillovers to neighboring cities under the economic-geography weight matrix; its promotion effect is most obvious in eastern and western cities, with significant spillovers across regions under the economic-geography matrix. These findings provide insights for cross-regional collaborative environmental governance in the digital era.
