Abstract

This study exploits the exogenous policy shock stemming from the establishment of the Shanghai Commercial Paper Exchange (SHCPE) to empirically examine the impact of commercial paper digitisation on corporate debt default risk. Using a difference-in-differences model with data from China’s A-share listed firms (2011–2022), we find that institutionalised digitisation driven by SHCPE significantly reduces debt default risk for commercial paper-reliant firms. Mechanism analyses confirm that risk mitigation operates by enhancing operational capacity through accelerated settlement, optimising internal capital allocation via improved liquidity, and reducing debt financing costs by alleviating information asymmetry. These findings provide micro-level evidence on how regulatory technology reshapes corporate financial resilience and offer critical insights for financial infrastructure digitalisation.
