Drawing on institutional and strategic choice theory, we try to examine how existing radio stations come to adopt a imitation decision in a competitive industry. We argue these imitation decisions are affected by institutional variables and strategic behavior in the context of Taiwanese commercial radio broadcasting industry. Hypotheses are developed and tested for a sample of 54 radio stations. Overall, the findings provide support for the argument that the adoption of a imitation decision by a radio station is importantly determined by structure of stockholder, joint networks, change of programs and professionalization. The results imply that talent enhance organizational innovation, and also imply that risk about the consequences of the change leads to adopt a imitation decision.
