After having mapped out the size of this sector, the study develops a way of classifying them into two categories on the basis of their actual record with respect to performance of innovations. Further we survey the policies that are available in India to promote FDI in R&D services. The study also identify the characteristics of these foreign R&D centres in terms of a number of indicators like their, size, domain expertise, physical location and then it distils out the interaction of these centres with India's National System of Innovation.
