Takada, Naoki：Yaichi Aoshima：Kazunari Matsushima：Akira Izumi
『International Journal of Technology Management』 Vol.99 No.1-2 pp127-146 （2026/02/25）

This study investigates international knowledge spillovers arising from government-funded R&D projects (GFPs). While GFPs are often justified by their domestic benefits, their international effects remain less clear. We posit that GFPs amplify international spillovers by signalling technological promise: government selection legitimise…

Patent Quality: Towards a Systematic Framework for Analysis and Measurement

Higham, Kyle:Gaétan de Rassenfosse:Adam B. Jaffe
『Research Policy』 Vol. 50 Issue 4 （2021/05/01）

The quality of novel technological innovations is extremely variable, and the ability to measure innovation quality is essential to sensible, evidence-based policy. Patents, an often vital precursor to a commercialised innovation, share this heterogeneous quality distribution. A pertinent question then arises: How should we define and …
