  • A new approach to R&D intensity classes illustrated on manufacturing industries in South Africa   Order a copy of this article
    by Nazeem Mustapha, Lwando Kondlo 
    Abstract: This paper examines the suitability and usefulness of OECD definitions and cut-off levels for classes of R&D intensity as a classification scheme for developing countries. It does this by developing a method for determining R&D intensity classes from data mining techniques. This improves on the original methodology of Hatzichronoglou (1997) by using clustering methods to define the members and boundaries of a technology class. Previous applications of this methodology relied on arbitrary choices of cut-off levels for technology classes and considerations of stability over time. The approach demonstrated may be implemented on a global level, but is used to examine new categories of high-, medium- and low- R&D intensity at a local level, using data on South Africa. It identifies the electronics- communications sector as the only high-R&D intensity industry, and it determines that only two R&D intensity classes were evident between 2010 and 2015 in South Africa. The results suggest that there is currently no high-tech industry in South Africa, and that a strategy that seeks simply to promote the export growth of such sectors is na
