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 study investigates how in-house R&D as well as access to national and foreign knowledge sources influences the productivity of Chinese firms. For our main analysis we use data for 1,140 patenting firms listed at mainland China stock exchanges over the time-period 2001-2010. In-house R&D...

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...

The objective of this study is to investigate the relation between increasing Chinese high-tech exports and the technological capabilities of Chinese companies. China s recent innovation policy provides substantial incentives for companies to pursue technological upgrading and...

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,...

The objective of this paper is to investigate the innovative performance of China's NIS in international comparison and the capacity of China's NIS in creating indigenous innovation. We provide insights drawing upon patent data and using patent families to determine the value of the underlying...

The global economic landscape has fundamentally shifted from the paradigm of globalization to renewed concerns regarding the risks and rewards of technological interdependence. This shift has sparked a critical discussion on technology sovereignty. This concept refers to a country's ability to...

We study the technology sovereignty of Europe, the US, China, Japan, and Korea. By examining citations from PCT patents filed from 2000-2020, we assess the bilateral and global influence of inventions. We highlight four insights. First, the US shows superior technology sovereignty through its...

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...

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...
