“…To gain additional insight, we move from an input‐based analysis (e.g., R&D expenditures) based on government statistics to an output‐based analysis of automotive‐related patents. This approach is consistent with other studies that examine manufacturing R&D (see for example, de Rassenfosse, Schoen, & Wastyn, ; DeBackere & Luwel, ; Guellec and van Pottelsberghe de la Potterie, ; Le Bas & Sierra, ). As these authors note, patents are a useful tool to measure R&D outputs.…”
