Abstract

The study aims to estimate the impact of R&D expenditure and patenting on the performance of firms using productivity, profitability and Tobin's q ratio as the performance indicators. The study uses firm-level data of 489 high- and medium-technology firms during the period of 2000-2010. We employ relatively a new source of data particularly in the context of India, firm-level patent granted, that has not been explored earlier. The study finds that firms patenting result in productivity improvement of firms, whereas R&D expenditure does not. The study further finds the evidence of positive impact of patenting on financial performance of firm with significant differences between foreign and domestic firms.
