AbstractUtterback and Abernathy (1975) developed a dynamic innovation model to explain the patterns of product and process innovation and to show which types of innovation would be most strategically appropriate for firms with particular objectives. In this paper the relation‐ships between type and/or source of innovation and a number of firm‐characteristic variables are examined. Loglinear regression is employed to determine the extent of the postulated relationships in a set of actual industry data on product innovation. The loglinear model provided results which were highly consistent with predictions made on the basis of previous research into product and process innovat
