Abstract
After The Bayh Dole Act in the US and related laws in other countries, the increasing commercialization of university discoveries has initiated a controversy on the impact for scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on research work and publication. This paper empirically examines the emerging anti-commons effect of academic patenting on knowledge production after Taiwan after Science and Technology Basic Law. Through a panel dataset of 400 professors, including patent inventers and non-patent inventors, in National Tsing-Hua University during 1999~2010, the results reveal that the anti-commons effect is not happen in publication quantity, quality, and variety. In contrast, they reveal that the relationship between patent activities and publication performance is complementary, not substitute, in National Tsing-Hua University. Especially, this paper examines the pre-patent and post-patent period, and discovers that the change in the behavior of professors can be traced to the pre-patent period.
