Literature on the link between market structure and industrial innovation is surveyed. Part II focuses on the so-called Schumpeterian hypothesis that large firm size, diversification or monopoly power is conducive to innovation and technical progress. Both empirical studies and theoretical developments are reviewed; for the former, the difficulties are catalogued and for the latter, a critique of recent trends is developed. The effect of innovation on market structure is taken up in Part IV, while Part V portrays the merits of the new approach of Nelson and Winter in their An Evolutionary Theory of Economic Change.
See M.I. Kamien and NX. Schwartz, ‘Market structure and innovation : a survey’, Journal of Economic Literature, XIII, March 1975, pp.1-37; F. M. Scherer, Industrial Market Structure and Economic Performance, Rand McNally, Chicago, 1980; D. A. Hay and D. J. Morris, Industrial Economics: Theory and Evidence, Oxford University Press, Oxford, 1979; and C. KittiandC. L. Trozzo, The Effects of Patents and Antitrust Laws, Regulations and Practices on Innovation, Vol. 1, US National Science Foundation, 1976.
R & D/research measures incorporate invention as well as post-innovation development work by firms: thus such convenient measures do not consistently reflect extent or rates of innovation. In a series of quite separate studies of significant inventions it was found that only a small proportion originated from within major firms in respective industries. The vast majority emanated from a variety of individual efforts outside of the industry, or from small firms. However, if innovation is defined as incorporating a sustained development effort, then these results are consistent with those of Freeman and others who find that large corporate R&D looms large. I am indebted to Ian Inkster for this point.

cf. J. F. Reinganum, ‘Practical applications of game theoretic models of R & D’, American Economic Review, 14, 2, May 1984, pp.61-66. R. K. Sah and J. Stiglitz, The invariance of market innovation to the number of firms’, RAND Journal of Economics, 18, 1, Spring 1987, pp.98-108, have recently used the concept of Bertrand competition to model a ‘winner-take-all’ patent race. They find that the number of firms has no effect on the pace of innovation, and under more stringent conditions, on R & D expenditures. Surprisingly, they now conclude that market expenditure on R & D is less than the socially optimal level. They also claim that efficiency will only be attained if each firm undertakes a single research project. The authors note that this may be hard to enforce!

Another key heterodox work is Kay, op. cit. This presents a very useful empirical and theoretical critique of the rational model of innovation (pp.13-40), and develops an alternative approach based on concepts from general systems theory.
