英文文献：Patents in the Long Run: Theory, History and Statistics
英文文献作者：Claude Diebolt,Karine Pellier
英文文献摘要：
This paper examines the structural and spatial dynamics of patents in France, Germany, Japan, the United Kingdom and the United States. The time series are extracted from an international, comparative and historical database on the long term evolution of patents in 40 countries from the 17th century to 1945 and in more than 150 countries from 1945 to present (Diebolt and Pellier, 2010). We found strong proof of infrequent large shocks resulting essentially from the major economic and political events formed by the two World Wars in the twentieth century. Our results question the autonomous process, i.e. the internal dynamic of the patent systems. Wars seem to push innovation and finally the economic growth process itself. We further investigated the role of innovation in economic growth through a causality analysis between patents and GDP per capita. Our major findings support the assumption that the accumulation of innovations was a driving force only for France, the United Kingdom and the United States during the post World War II period.
