This paper explores the interactions among incubators within a particular region, a concept that is rarely mentioned and analyzed in the previous literature. Three hypotheses regarding the causes of the competition and cooperation among the incubators were proposed as a result of the review of the previous literatures. The hypotheses were then tested through a case study discussed in this article that includes the three incubators, all of which specialize in technology, within the Hsinchu region. The case was investigated using data collection and interviews. As a result of the investigation, it was concluded that the interactions among the incubators have facilitated the development and complicated the management model of each incubator. The cooperation and competition that exist among the incubators have improved them significantly since their establishments. It is suggested that the policy makers should consider this type of interaction when developing incubators and utilizing the research results from this paper to manage incubators.
