Abstract
Based on 2332 items in USPTO Patent Database of nanomaterial industry, using negative binomial regression model, the paper examines the influence of science citation on the firm's patent quality. Empirical test results show that quantity and quality of the Science Citation is positively related to patent quality, while the time lag of the Science Citation is negatively related to patent quality. The results indicate that significant technological invention is related to scientific discovery in nanomaterial industry, and the performance improvement of nanotechnology development depends on the close combination of frontier science and technology.关键词
