Abstract: This paper investigates the National S&T Awards evaluation process，based on actor network theory. It is found that there are lots of network connections among candidates, awards evaluation organizational units, and awards evaluation experts. The connections are enhanced not only by human actors’ interaction but also by non-human actors’ active involvement. The tension of network connections embodies benefit exchange between bothsides, and irregularities in evaluation process partly reflect the characteristics of national science and technology awards’ actor network. For the improvement of science and technology awards system, the interaction of human actors and non-human actors should be considered systematically.
