A patent analysis of global food and beverage firms: The persistence of innovation
We explore whether current innovation has an enduring effect on future innovative activity in large, global food and beverage (F&B) companies. We analyze a sample of 16,698 patents granted in the United States over the period 1977 to 1994 to 103 F&B firms selected from the world's largest F&B multinationals. We test whether patent time series are trend stationary or difference stationary in order to detect how large the autoregressive parameter is and how enduring the impact of past innovation in these companies is. We conclude that the patent series are not consistent with the random walk model. The null hypothesis of a unit root can be rejected at the 5% level when a constant and a time trend are considered. Both utility and design patent series are stationary around a constant and a time trend. Moreover, there is a permanent component in the patent time series. Thus, global F&B firms show a stable pattern of technological accumulation in which “success breeds success.” “Old” innovators are the ones to foster both important changes and new ways of packaging products among F&B multinationals. The effect of past innovation is almost permanent. By contrast, other potential stimuli to technological change have only transitory effects on innovation. Patterns of technological accumulation vary in specific F&B industries. Past experience in design is important in highly processed foods and beverages, but not in agribusinesses and basic foodstuffs. Patterns of technological accumulation are similar in both smaller multinationals|newcomers and large, established multinationals.
