On the origins of the worldwide surge in patenting: an industry perspective on the R&D-patent relationship
从行业层面分解研发与专利的关系，利用19国18行业1987-2005年数据，发现专利申请变化不仅源于研发生产率，还受企业专有策略和全球化影响，对理解专利激增原因有参考价值。
This article decomposes the R&D–patent relationship at the industry level to shed light on the sources of the worldwide surge in patent applications. The empirical analysis is based on a unique data set that includes five patent indicators computed for 18 industries in 19 countries covering the period from 1987 to 2005. The analysis shows that variations in patent applications reflect not only variations in research productivity but also variations in the appropriability and filing strategies adopted by firms. The results also suggest that the patent explosion observed in several patent offices can be attributed to the greater globalization of intellectual property rights rather than to a surge in research productivity.
