Measuring innovative performance: is there an advantage in using multiple indicators? 总被引：10，自引：0，他引：10
The innovative performance of companies has been studied quite extensively and for a long period of time. However, the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators. So far the variety in terms of constructs, measurements, samples, industries and countries has been substantial. This paper studies the innovative performance of a large international sample of nearly 1200 companies in four high-tech industries, using a variety of indicators. These indicators range from R&D inputs, patent counts and patent citations to new product announcements. The study establishes that a composite construct based on these four indicators clearly catches a latent variable ‘innovative performance’. However, our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high-tech industries. 相似文献

This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions. Using global patent data, this paper empirically investigates the importance of both the quantity and quality of innovation on economic growth, controlling for past measures of inventive inputs. Moreover, our research examines how innovation inputs can be translated into per capita growth under the various economic structures and stages of economic development. Based on a sample of 58 countries for the period 1980–2003, our empirical results indicate that countries hosting firms with higher quality patents also have higher economic growth. Furthermore, we have some evidence that those countries that increase the level of patenting also witness a concomitant increase in economic growth. 相似文献

Research into invention, innovation policy, and technology strategy can greatly benefit from an accurate understanding of inventor careers. The United States Patent and Trademark Office does not provide unique inventor identifiers, however, making large-scale studies challenging. Many scholars of innovation have implemented ad-hoc disambiguation methods based on string similarity thresholds and string comparison matching; such methods have been shown to be vulnerable to a number of problems that can adversely affect research results. The authors address this issue contributing (1) an application of the Author-ity disambiguation approach (0170 and 0175) to the US utility patent database, (2) a new iterative blocking scheme that expands the match space of this algorithm while maintaining scalability, (3) a public posting of the algorithm and code, and (4) a public posting of the results of the algorithm in the form of a database of inventors and their associated patents. The paper provides an overview of the disambiguation method, assesses its accuracy, and calculates network measures based on co-authorship and collaboration variables. It illustrates the potential for large-scale innovation studies across time and space with visualizations of inventor mobility across the United States. The complete input and results data from the original disambiguation are available at (http://dvn.iq.harvard.edu/dvn/dv/patent); revised data described here are at (http://funglab.berkeley.edu/pub/disamb_no_postpolishing.csv); original and revised code is available at (https://github.com/funginstitute/disambiguator); visualizations of inventor mobility are at (http://funglab.berkeley.edu/mobility/). 相似文献

Applying a within-firm perspective to the topic of the division of innovative labor, I explore the organization of scientific discovery at the firm level — specialized or integrated with invention. Using data on inventors and authors related to U.S. publicly-traded science-performing firms for the period 1980–2015, the paper deepens our understanding of the determinants and the tradeoffs associated with the strategic choice of scientific discovery organization. I show that integration is related to a tradeoff between short-term applied R&D and long-term fundamental R&D; while integration is beneficial for invention, it has adverse effects on its scientific output, which decrease invention in the long run. The negative relationship between integration and publication reduces the direct increase in patents due to integration by approximately 90%. To better understand firms’ R&D organizational choice, I present internal and external factors that have implications on the benefits and costs associated with integration: reliance on science, stage of technology, external market for technology, and R&D spillins. Finally, I present consistent implications in terms of market value and show that value creation is related to organizational structure. 相似文献

Both China and India have been experiencing a historical take-off in the use of intellectual property rights (IPR). In terms of trademark applications filed with domestic IP offices in 2009, the evidence demonstrates that China now ranks 1st worldwide and India 5th, while for patent filings China ranks 3rd worldwide and India ranks 9th. This performance is remarkable as both China and India experienced negligible demand for IPR protection as recently as two decades ago. The IPR take up trends in these two countries are analyzed in detail, highlighting the structure of patent and trademark demand since 1990. Specifically, the available series are broken down and analyzed according to: (i) national versus foreign origin of patents and trademarks; (ii) technological (IPC) and trademark (NICE) classes; and (iii) the major individual patent users in each country. The data used refers to applications in the Chinese and Indian IP offices although the demand from residents of these two countries in both the international and other national systems is also assessed. Beyond the existing momentum in IPR registrations by China and India and their capacity to maintain it into the near future, the paper addresses practical questions about the strategies, motives and benefits behind the current trends. In particular, we seek to evaluate the capacity of both China's and India's National Innovation Systems to internalize the potential returns of this increasing demand for IPR. The insight reached finds that should both China and India sustain their current IPR growth rates, they will be able to catch up with the most advanced economies within the time span of a few decades. 相似文献

Appropriate intellectual property protection and economic growth in countries at different levels of development 总被引：1，自引：0，他引：1
This paper examines how the role of patents and utility models in innovation and economic growth varies by level of economic development. Using a panel dataset of over 70 countries, we find that patent protection is an important determinant of innovation and that patentable innovations contribute to economic growth in developed countries, but not in developing. Instead, in developing economies, a minor form of intellectual property rights (IPRs) - namely utility models - is conducive to innovation and growth, controlling for other factors. Using Korean firm level data as a case study, we find that utility model innovations contribute to firm performance when firms are technologically lagging and that those minor innovations can be a learning device and thus a stepping stone for developing more patentable inventions later on. Upon reaching higher levels of technological capabilities, firms become more reliant upon patents and less on utility models. Thus the lesson here is that patent protection enhances innovation and economic growth in countries where the capacity to conduct innovative research exists. Where this capacity is weaker, a system that provides incentives to conduct minor, incremental inventions is more conducive to growth. The significance of this paper is to emphasize the importance not just of the strength of IPRs but of the appropriate type of IPRs for economic development. 相似文献
