Abstract

Against the backdrop of the digital economy and high-level opening-up, this study uses A-share listed companies (2007–2024) to explore OFDI supply chain spillovers’ impact on domestic enterprises’ digital technology innovation via the two-way fixed-effects model and related tests. Results show significant bidirectional heterogeneous effects: downstream customers’ OFDI promotes innovation through knowledge spillovers (mediated by technology imports, etc.), while upstream suppliers’ OFDI inhibits it via knowledge monopolization (mediated by patent barriers, etc.), validating spillover asymmetry. Robustness tests confirm reliability. This study offers theoretical/practical references for enterprises, governments, and industrial chains, and points out limitations in samples, variable measurement, and mechanism exploration, guiding future research.
