### Overview
- Research question: How much do firms benefit from foreign R&D and through what channel?
- Approach: Construct a global network of corporate innovation using more than 1.5 million patents granted to firms in OECD countries.
- Hypothesis tested: The “international technology sourcing” hypothesis—that foreign innovation activities tap into foreign R&D and improve home productivity through knowledge spillovers.

### Data and scope
- Data source: Patent-based global network of corporate innovation covering firms in OECD countries.
- Scale: More than 1.5 million patents.
- Publication details:

### Key findings
- Firms with stronger inventor presence in technology frontier countries benefit disproportionately more from their R&D.
- The strength of knowledge spillovers depends on the direction of technology sourcing.
- Knowledge externality is larger for firms in technology frontier countries than for firms in non-frontier countries.
