This paper analyzes the spatial spillover effects of U.S. inflation on 14 OECD sample countries from 2019 to 2022 using the Spatial Durbin Model (SDM) and the TVP-SV-VAR model. The study finds that: 1) U.S. inflation exhibits significant spatial spillover effects, with all sample countries experiencing sustained positive shocks, though the intensity of these effects varies due to regional economic and geographical characteristics. 2) The spillover effects follow a "core-periphery" geographic attenuation pattern, where geographically proximate countries experience stronger and more persistent impacts. 3) The role of competition policy in regional inflation governance differs: the EU employs competition policy to ensure the effective implementation of a unified monetary policy and a single market, whereas emerging markets focus on using competition policy to curb excessive market concentration and accelerate supply chain restructuring. 4) Spatially adjacent regions adopt coordinated governance mechanisms and shorten supply chain distances to enhance resilience against risks. Moreover, early and proactive competition policy interventions significantly improve inflation control effectiveness. Based on these findings, China can enhance policy efficiency by: closely monitoring U.S. inflation trends; leveraging its geographic characteristics to regulate market concentration through competition policy; shortening supply chain distances; and optimizing the spatial configuration of key commodity supply chains. Additionally, strengthening the role of competition policy in inflation governance, improving coordination with other policies, and implementing differentiated competition law enforcement strategies tailored to various inflation drivers can help mitigate the spatial transmission speed and impact of imported inflation.
