The Innovation†R&D Nexus in an Emerging Economy: Evidence from the Indian Manufacturing Sector

Australian Economic Papers, 2018, vol. 57, issue 1, 35-54

Abstract: While R&D is considered an important input for innovation, its relationship with the output of the innovation process continues to remain enigmatic, especially in developing countries with low levels of domestic research. Using patents and knowledge capital stock as proxies for the output and input of the innovation process, we study their nexus in the emerging economy of India using a large sample of manufacturing firms over the period 2001–2010. Using a specification that addresses the problem of ‘excess zeroes’ in count data, the firm's non†technical knowledge stock as an additional factor of the success with which R&D transforms into patents, and a linear feedback mechanism that yields consistent estimators, we find that a one unit increase in knowledge capital likely raises expected patent count by only about 4.3% at most. Further, although patenting experience, resource access and knowledge spillovers are strongly significant in explaining patent counts, the magnitude of these effects is marginal at best. In brief, evidence for the knowledge production function is rather weak even in the context of a dynamic developing economy.
