R&D SPILLOVER, FIRM SIZE AND IN-HOUSE R&D: PANEL DATA EVIDENCE FROM ELECTRONICS GOODS SECTOR IN INDIA

This study examines the impact of R&D spillover and firm size on the R&D intensity of electronic firms operating in India for the time period 2000-2015. The study finds that firms benefitting from R&D spillover in their line of business are spending more on in-house R&D, indicating complementarity between R&D spillover and R&D efforts. When we consider possible R&D spillover with firm size, the positive association between R&D spillover and in-house R&D activity holds after a certain threshold of firm size is reached. A probable implication for the moderating influence of firm size suggests that large-sized firms have financial resources and the capability to assimilate technological knowledge in their product designs and processes. An inverted-U relationship between firm size and R&D suggests that support and assistance with the cost of research and development can spur the innovation incentive of small- and medium-sized firms. The empirical finding indicates that fringe firms in the electronics sector aim at developing new technology. The import of intermediate inputs appears to be negatively associated with in-house R&D. This suggests substitutability between imported intermediaries and R&D activity. In the case of R&D reporting firms, the coefficient of embodied technology and capital intensity turns out to be positive and significant. As it remains, an increase in the import of capital goods promotes in-house R&D of electronic firms. At the same time undertaking R&D activity in a high-tech sector is capital intensive. Hence, firms require capital reserves to engage in innovative activities and remain competitive.
