SOME NEW EVIDENCE ON THE DETERMINANTS OF LARGE-AND SMALL-FIRM INNOVATION

Empirical analyses presented by Acs and Audretsch suggest differences in the market structure determinants of innovation between large and s mall firms in U.S. manufacturing. The evidence they offer is ambiguous . By using data for a different country (The Netherlands), a different measure of innovation and a different aggregation level, we offer new evidence, allowing a revaluation of the findings for the U.S. materia l. Moreover, the influence of the market structure determinants does n ot appear to differ between a period of sluggish growth (1983) and one of relatively high growth (1989).
