Firm R&D Behavior and Evolving Technology in Established Industries

Abstract

One of the key mechanisms of firms' strategic renewal is R&D, and a key driver of the intensity of R&D is industry context. A number of theories develop propositions linking industry factors to firm R&D behavior, but these theories lack consensus. To date empirical tests have been unable to resolve the competing predictions due to lack of time-varying measures of technology. We create new measures for technology then conduct a test of the competing theories. Our results indicate that the data best match a model of innovative behavior in which firms invest in R&D principally to regain eroded advantage rather than to pursue the new frontier.
