This paper draws upon the traditions of social construction of technology and actol-net work theory, in an attempt to show that just as these approaches have been used to expose the contingent nature of 'technical' change, they can also be adapted to show the contingency of the 'social' aspects of technology, such as redundancy and technological unemployment, which have in recent years assumed an almost unassailable sense of inevitability. This process is begun when technology is viewed as a social network. Then focusing on the production phase in the life cycle of a technical system, it is argued here that the,jettisoning of both people and technical resources from the network may get presented as part of technology's 'natural' trajectoly, but is often part of the (socio-technical) 'heterogenous engineering' necessary for the stabilization of that technology. and consequently need not be seen as inevitable. 相似文献

Control of SO2 emissions from power plants: A case of induced technological innovation in the U.S. 总被引:1,自引:0,他引:1
This paper investigates how the details of government actions induce innovation—the overlapping activities of invention, adoption and diffusion, and learning by doing—in “environmental technology,” products and processes that either control pollutant emissions or prevent emissions altogether. It applies multiple quantitative and qualitative measures of innovation to a case subject to several “technology-push” and “demand-pull” instruments: sulfur dioxide control technology for power plants. The study employs analyses of public R&D funding, patents, expert interviews, learning curves, conference proceedings, and experience curves. Results indicate that: regulation and the anticipation of regulation stimulate invention; technology-push instruments appear to be less effective at prompting invention than demand-pull instruments; and regulatory stringency focuses inventive activity along certain technology pathways. Increased diffusion of the technology results in significant and predictable operating cost reductions in existing systems, as well as notable efficiency improvements and capital cost reductions in new systems. Government plays an important role in fostering knowledge transfer via technical conferences, as well as affecting the pattern of collaborative relationships within the technical research community via regulatory changes that affect the market for the technology. Finally, the case provides little evidence for the claim that cap-and-trade instruments induce innovation more effectively than other instruments. 相似文献

I examine the determinants of new pharmaceutical launches since 1980 in G7 nations. Both market and firm characteristics, and their interaction, are important in explaining entry. New drugs are 1.5 times more likely to be launched in markets that share a border or a language of a drug company's country of headquarters. The effect of competition depends on the characteristics of both the potential entrant and incumbents: domestic entrants prefer to compete with domestic incumbents. Despite the potential for licensing and low transportation costs, the match between the innovating firm and market conditions remains an important determinant of entry. 相似文献

This paper elucidates the underlying economics of the resource-based view of competitive advantage and integrates existing perspectives into a parsimonious model of resources and firm performance. The essence of this model is that four conditions underlie sustained competitive advantage, all of which must be met. These include superior resources (heterogeneity within an industry), ex post limits to competition, imperfect resource mobility, and ex ante limits to competition. In the concluding section, applications of the model for both single business strategy and corporate strategy are discussed. 相似文献
