Abstract
This
study investigates how digital goods trade affects national innovation capacity
through dual mediating channels. Using panel data from 69 countries over
2011-2020, we construct a multiple mediation model to test the parallel
mediating roles of domestic research and development (DRD) and international
technology cooperation (ITC). Results show that digital goods imports
significantly enhance innovation through both DRD and ITC, with the ITC channel
exhibiting a substantially larger mediation effect. However, digital goods
exports show no significant mediating effects through either channel.
Heterogeneity analysis across five digital goods categories reveals that the positive effects of imports are
concentrated in communication equipment and electronic components, while
exports of computer peripherals exhibit a significant direct effect. These
findings extend the trade-innovation nexus to the digital goods context, reveal
asymmetric mediating mechanisms between imports and exports.
