Abstract: | Technological innovations are the substance of technology and the drivers of its evolution. This process was studied by analyzing the US patent data base, getting information on types of innovation and on their trends.It was found that the evolution of a technology depends upon its annexing multitechnology innovations. Ascending technologies utilize wide-range innovations, while mature technologies utilize narrow-range innovations. The findings are summed up in a model that shows the life cycle of a technology, from emergence to maturity.The model can be applied at a laboratory level, at a firm strategy level, as well as at the national level. Some examples are presented to illustrate applications. |
