Scalability versus flexibility: firm size and R&D in Indian industry

This article has examined the impact of firm size on R&D spending for a panel of several thousand Indian firms, for a period of seven years from 1999-2000 to 2005-2006. The average levels of R&D spending are low but for firms that do undertake R&D the average levels of R&D spending are much higher. The results of the analysis for all the manufacturing sector firms have shown that larger firm size is associated with a higher probability of R&D spending. In non-linear estimation the squared term is negative denoting that after a particular threshold firm size has no effect on R&D spending. When only the R&D spending firms are evaluated then size has a mild impact on R&D spending and in a non-linear framework the effect of size disappears signifying that both the relatively smaller and larger firm alike seem to be motivated in building capabilities in the post-liberalization period of the Indian economy.
