This article analyzes the organizational evolution of innovative activity in the contemporary high-tech industry. It has been argued that by showing illuminating examples and proposing theoretical explanations, the innovation process has been fragmented and distributed among several organizations. In other words, ‘division of innovative labor’ emerges. However, one of the problems of this argument lies in its lack of systematic empirical analysis. Using the United States Patent and Trademark Office patent database, this article analyzes the organization of innovative activity in the US semiconductor industry. It is shown that ‘technological specialization’ has not occurred in this industry as a whole. In addition, it is also shown that there are two distinct modes of development of technology, namely, ‘specialized development of technology’ and ‘diversified development of technology’, in which the share of the latter has been steadily increasing. These results imply that contrary to the earlier conventional arguments, division of labor is not a common phenomenon in the production of technological knowledge. 相似文献

This paper examines the linkage between patenting and export performance for selected countries at the level of technology fields. Some empirical studies show considerable correlation between the patenting behavior of countries and their economic success in international markets. Adding to the existing literature, the aim of this analysis is to assess whether the indicators that are supposed to reflect patent value—such as patent citations or family size—have any explanatory power in estimating the export value of countries by technology fields. 相似文献

This study proposes a quantitative method for investigating the structure of international technology diffusion. By using network analysis, this study defines the structural configuration of each country within the international diffusion network by measuring its degree, closeness, and betweenness centralities. In addition, this study distinguishes between embodied technology diffusion, measured by multilateral trade, and disembodied technology diffusion, measured by patent citations, in individual countries. This study empirically tests a sample data set of international technology diffusion taken from 48 countries. The empirical results show that the structural configuration of countries exhibits similar patterns in both embodied and disembodied diffusion networks. Significant global stratification patterns exist in the capability of national international technology exportation and brokerage advantages. Moreover, this study distinguishes four blocks of countries that play different roles in international technology diffusion: the leading countries provide a source of technological knowledge; an intermediate group diffuses the knowledge acquired from the source; a third group is in the process of initiating the export of technological knowledge; and a final group of countries absorbs technological knowledge without reciprocal exportation. Finally, this study identifies two types of catch-up strategies that newly industrialized or developing countries can use to move up the international technology stratification. 相似文献

South Korea, Taiwan, Singapore, Hong Kong, China and India have become much larger force in the world economy. Due to the enormous contribution of the use of information and communication technologies (ICT) in economic growth, this study investigates four main issues related to technological innovation and knowledge network in ICT among six countries. First, indicators of technological innovation were evaluated and used to compare capability of technological innovation in ICT between the six countries. Secondly, differences in innovation configurations among six countries were manifested. Thirdly, relative innovation strengths of these six countries were examined in five sub-technological fields. Finally, this study consists of analyzing the interactions into knowledge network among them; moreover, this study manifests the difference of knowledge network in five sub-technological field of ICT. The empirical findings of this study, based on analysis of a patent and citation dataset comprised of all patents granted by the U.S. Patents and Trademark Office (USPTO) to assignees in six countries from 1976 to 2006, are helpful to understand the comparative development of technological innovation of ICT in six countries. 相似文献

This study investigates the research and development (R&D) and patenting activities of foreign firms in China. Utilizing a panel dataset of Japanese affiliates during the period 2001–2007, we first examine the determinants of R&D activity and find that local market-oriented firms place more emphasis on R&D, whereas process export-oriented firms are less likely to conduct R&D. Affiliates within a large business group that has more affiliates have a higher propensity to undertake R&D. Using only firms with positive R&D expenditures, we next estimate the patent production function. Results indicate that the patent elasticity of R&D for Japanese affiliates is high, suggesting that they are more productive on patent production than other firms. Moreover, local market-oriented firms do need more patents to protect their products, whereas scientific firms demonstrate a lower willingness to register patents in China. 相似文献

AbstractEvent studies of stock price movements have been used to assess the anticompetitive impact of ‘reverse-payment’ settlement of patent disputes in the drug industry. Evidence for an anticompetitive effect is found when financial markets reward a brand manufacturer with larger stock market capitalization – signaling the agreed upon generic entry date was more profitable (i.e. later) than investors’ expectations. In practice, reverse-payment cases can involve multiple generic competitors and settlements. This paper considers how event-study methodology applies in such cases, with a study of the stock price movements of Cephalon, manufacturer of the drug Provigil. Cephalon entered into four patent litigation settlements with potential generic competitors over a two-month period beginning in December 2005. Event study methods can readily be applied to such a case. Cephalon’s total increase in stock value across four narrow windows around each settlement totaled over $1.0 billion, indicating the agreements delayed generic entry beyond the market's expectation. 相似文献
