The adverse economic impacts of the 1962 Kefauver-Harris Amendments to the Food, Drug and Cosmetic Act have transformed the U.S. pharmaceutical industry. The key elements of this transformation include declining rates of innovation, huge increases in R&D costs and risks, lowered profitability, and an erosion of U.S. technological leadership. U.S. pharmaceutical firms must develop new, creative R&D strategies in order to cope with this complex and demanding environment. U.S. firms have responded to more stringent domestic regulation by sharply increasing both foreign R&D expenditures and initial clinical testing of new chemical entities at foreign locations.New patterns of project selection strategies have begun to emerge in the 1970s. As the total number of R&D projects has been cut back, pharmaceutical firms have focused resources on those disease areas with the highest epidemiological importance. To cope with the increasing riskiness of drug R&D firms have shifted dollars from research to development. Pharmaceutical firms are also likely to alter their strategies for discovering new drugs. As firms reduce explorative, basic research, more structured, engineering approaches will receive increased emphasis. Because individual drug companies are likely to have reduced capacity for originating drugs within their own laboratories, competition among firms for access to new compounds and research ideas is likely to in tensify.  相似文献

This paper examines the meaning of context in relation to ontology based query expansion and contains a review of query expansion approaches. The various query expansion approaches include relevance feedback, corpus dependent knowledge models and corpus independent knowledge models. Case studies detailing query expansion using domain-specific and domain-independent ontologies are also included. The penultimate section attempts to synthesise the information obtained from the review and provide success factors in using an ontology for query expansion. Finally the area of further research in applying context from an ontology to query expansion within a newswire domain is described.  相似文献

For more and more firms product innovation is becoming the key to survival and future growth. Successful product innovation cannot be based only upon inspiration, fantasy and random ideas; in most firms a purposeful and systematic approach also is required. Information is a key concept in this context. As product innovation activities are very different from day-to-day activities, a special information system is required.Based on an in-depth study of a large firm, it appears that systematic innovation requires: (a) a sound business concept with future oriented strategies and policies; (b) a competent staff who master the necessary tools; (c) an efficient organization with an appropriate information system; (d) relevant methods for diversification studies and product planning; and (e) development of individual products based on systematical provision of information about user needs and proper specification of requirements.In small firms innovations are based more on the entrepreneurial approach. Such firms often demonstrate a very innovative attitude, but many of them are hampered by lack of skills in marketing and management. They also lack supporting services which can provide information about the environment.Considering the importance of small firms in economic development and social progress, they should be given support in their innovative attempts. This can be done by organizing innovation centers which arrange studies, develop courses, and give practical assistance to firms engaged in innovative work. Governments should develop policies and provide information stimulating both small and large firms to innovations that are more desirable from a social point of view.  相似文献

The importance and contribution of new technology-based firms (NTBFs) to long-term economic development is at the centre of a controversial debate. This paper provides an overview of the current status of research on various issues concerning NTBFs in Germany. The issues covered include the incidence of start-up firms in Germany's technology-intensive sectors and their regional clustering. The review also shows that NTBFs play an important role with regard to the transfer, adoption and diffusion of technology. The public support and policy initiatives for NTBFs in Germany are also discussed.  相似文献

This paper deals with the relationships between firms and communities in open source software (OSS). A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.  相似文献

This explorative paper investigates how firms in the global data-processing industry that seek patent protection for their innovations in Europe have coped with the patentability requirements of the European Patent Office. Starting from a continuous research spectrum with basic research on the one extreme and development on the other, the main hypothesis is as follows: firms that carry out more basic research are more successful in passing the patent office than firms that focus more on development. Basic research explores more novel and unknown technical paths, while development aims more at modifying and redesigning existing products. Therefore, the results from more basic-oriented research are expected to fulfill the patentability requirements relatively more often than the results from development. This hypothesis is tested and largely confirmed for the global data-processing industry (with a sample of 44 firms) in the period 1986–1990, using indirect variables for basic research and development.  相似文献

In the fall of 1945, Secretary of Commerce Henry Wallace handpicked Edward Condon, a respected theoretical physicist, to become director of the National Bureau of Standards. Already regarded by many academic and industrial scientists as a second-rate research institution, the Bureau had deteriorated further during the Great Depression. An ardent New Dealer who favored government action to prevent anticompetitive behavior in the marketplace, Wallace claimed that giant corporations leveraged their extensive patent holdings and research capabilities to manipulate markets and restrict competition at the expense of smaller firms without similar resources. Through a revitalized Bureau of Standards, Wallace intended to mitigate monopolistic behavior among large companies by transforming the Department of Commerce into an effective clearinghouse for scientific research that would stimulate technological innovation in small businesses. The Bureau's postwar expansion, however, foundered on congressional efforts to dismantle the legacies of the New Deal, Condon's lack of commitment to the technical requirements of the small business community, and the intense competition for resources within an institutionally pluralist federal research establishment dominated by the exigencies of the Cold War. Without sufficient financial support from congressional appropriations committees, Condon turned to the military to fund new research programs at the Bureau of Standards. These programs, however, owed their institutional growth to the demands of the national security state, not to the fading influence of Henry Wallace's New Deal liberalism.  相似文献

This article analyzes the impact of loans secured by patents (LSPs) on the intellectual property and innovation strategy of technological firms that benefit from them. The literature mostly emphasizes that LSPs, by reducing the risk taken by lenders in case of borrowers' default, facilitate the financing of technological firms. However, it remains silent on the impact of LSPs on the behavior and strategy of borrowers. With regard to this second point, our research suggests that LSPs are not neutral. In particular, we provide evidence that LSPs might induce technological firms to deviate from innovative activities toward more short-term strategies based on the monetization and litigation of their patents. We also show that financing groups might attempt to encourage this strategic change. Our research is based, first, on empirical insights provided by a qualitative analysis of publicly known LSPs offered by an international investment group and their consequences for four borrowers. Second, we propose a theoretical model that formally explores how LSPs might impact borrowers' strategies. Even though the welfare implications of these findings are difficult to evaluate, this research has likely important economic and managerial implications with regard to intellectual property management, the financing of innovation and the organization of the innovation process.  相似文献

The concept of the regional innovation system (RIS) has been developed into an important framework for evaluating innovation performance. The study reported in this paper explores the relationship between the RIS and the firm's innovation system (FIS) according to the basic premise that firms that better utilize sources of information (SI) available within their regional innovation system (RIS) perform better due effect this has in enhancing the firm's technological innovation capabilities (TICs). The different innovation capabilities of a firm are regarded as the key components of the firm's innovation system. The sources of information available within an RIS include external sources (EXT) and external expert organizations, the latter of which are referred to as knowledge-intensive business services (KIBS). This study also explores the dual role of KIBS as both sources of and bridges for innovation in the RIS. Data were obtained through a mailed survey using a self-administered questionnaire. The utilization concept and the dual role of KIBS were verified. The results show that externally available information affects all innovation capabilities of the firm, while external expert organizations affect only the firm's R&D and resources allocation capabilities. This study contributes to the RIS literature by providing empirical evidence on how firms can interact with the RIS by utilizing SI to enhance their TICs and achieve global competitiveness.  相似文献

The ability to access specialized complementary assets has been key to explaining how firms benefit from their technological innovations. When firms lack complementary assets the more likely they have to rely on markets for technology to profit from their R&D investments. We extend this view documenting the emergence of a new type of industry intermediary, Contract Development & Manufacturing Organizations (CDMOs), which provide access to complementary assets on a per-use basis. CDMOs allow firms to contract for complementary assets at variable costs without the need to invest in such assets internally. This opens up new product development paths, in which firms do not out-license their products to firms with complementary assets but sustain their development in-house using CDMOs. We highlight that the expansion of services offered by CDMOs changes the nature of the industry's source of competitive advantage and provide empirical evidence that the expansion of CDMOs is associated with a decline in the number of out-licensing deals among US biopharmaceutical firms. In so doing, the study explains how innovation intermediaries like CDMOs can have a profound effect on an industry's specialized complementary assets and the market for technology.  相似文献
