abstract

Using a panel of electronics firms listed on the Taiwan Stock Exchange, this paper explores the spillover of scientific research to the private sector by looking at the impact of the intensity a patent’s backward citation of scientific publications relative to citation of other patents on the patent-owning firm’s productivity. To identify the causal effect, we use measures of a firm’s financial constraints as instrumental variables to accountfor the potential endogeneity of scientific citation intensity of a patent. The empirical results suggest that the citation of scientific publications by a patent has a strong and positive effect on the patent-owning firm’s productivity.

6. Conclusion

Innovation is a major driver of economic growth and can increase the value added and competitiveness of an economy and its firms. Over the past 20 years, R&D expenditure and research investment have increased rapidly all over the world. Also, there was a dramatic increase in the number of patents approved. An invention usually benefits from knowledge spillovers from academic research and other inventions, as indicated by a patent’s citation of scientific publications or other patents. Increasingly, scientificpublications are being citedinfirms’patents (e.g.,Narinet al., 1997 and Branstetter and Ogura, 2005). This implies thatthe knowledge spillover from academia to industry has become greater. Our study explores the contribution of this kind of scientific linkage to a firm’s productivity.
