Abstract: Abstract Using China’s Comprehensive Cross-Border E-Commerce Pilot Zones (CCBEPZs) as a quasi-natural experiment, this paper draws on panel data from Chinese A-share listed companies (2011–2022) and employs a staggered difference-in-differences (DID) model to examine how CBEC platform ecosystems shape supply chain resilience (SCR) and firm-level innovation. Our findings are threefold. First, CBEC pilot zones significantly improve SCR: supply chain redundancy increases by 2.3 percentage points and the composite SCR index improves by 17.6%. Second, the platform ecosystem raises patent output by 23.1%, operating through transaction cost reduction (31.4% of total effect) and enhanced information access (25.7%). Third, digital transformation positively moderates both effects. Heterogeneity analysis reveals the most pronounced effects among non-SOEs, technology-intensive industries, and inland-region firms.
