Because China has become one of the largest applicants of PCT patents, it is of interest to compare the quality of Chinese and non-Chinese applications. We extend a quality index based on internationally comparable citation data from international search reports (ISR) to consider foreign,...

China recently surpassed the USA as the greatest global source of patent applications. However, without internationally comparable measures of patent quality it remains questionable whether China's patent expansion constitutes the rise of a new technological superpower. Our novel quality index...

We develop an index that compares the quality of Patent Cooperation Treaty (PCT) applications by considering citations generated by International Search Reports (ISRs). In its most restrictive variation, i.e. excluding citations from the home country and self-citations, the ISR index is not...

This paper analyses the influence of in-house R&D and external knowledge acquisition on the total factor productivity (TFP) of listed Chinese firms for the time period 2001-2010. We find a quantitatively important positive effect of in-house R&D. The achieved level of technological...

This paper analyzes how companies of immigrant entrepreneurs in knowledgeintensive industries differ from companies of native entrepreneurs with respect to start-up characteristics, firm survival and innovative performance. I focus on immigrants from the "recruitment countries" of south and...

In the past years Chinese firms increased their spending on R&D substantially and worked on achieving a higher quality level of R&D. We analyze whether different R&D activities show a positive influence on total factor productivity (TFP) for firms of different ownership types and across two time...

Considering China's policy-driven patent expansion, we validate domestic citations in comparison to foreign ones, which are exogenous to China's policy, as economic indicators. We derive internationally comparable citation data from international search reports. Whereas foreign citations show...
