制药业的联盟无论从理论上还是实践上,都得到了比较多的关注,但大多数关于它的学术分析都仅限于产业的个别环节。本文试图把制药业作为一个整体来分析,强调了制药业由于制度化市场引起的复杂性与技术发展引起的不确定性,并引用了一些基于数据的分析结果,检验了联盟这种组织方式在应付这种复杂性与不确定性时的作用。最后,本文也讨论了联盟能否为中国制药业提供机会。一方面,这种对具体行业的分析有助于加深对联盟的行为与效率的理解,另一方面,对联盟的理解也将有助于对制药业竞争的理解。 相似文献

The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history. In this new environment, scientific and technology policies should: (1) foster interactions among agents (whether public or private), (2) increase the effectiveness of public research, extension and funding institutions, (3) give sufficient freedom to researchers to set their research programs, and (4) monitor the quality of research (rather of research outputs). The evolution of innovation networks is analyzed looking at the development and diffusion of zero tillage (ZT) in Brazil. 相似文献

Increasing complexity and limits of organization in the microlithography industry: implications for science-based industries 总被引：2，自引：0，他引：2
Hiroyuki Chuma 《Research Policy》2006,35(3):394-411
This paper tries to clarify how current science-based industries become required to respond to their rapidly advancing complexity and what kinds of new organizational forms are inevitable to cope with such complexity. The microlithography industry is used for this purpose as a typical example. The central analytical concept is “interim modularity,” defined as the modular architecture at trial-and-error development and/or prototyping phases, to effectively orchestrate the dispersion of specialized knowledge and know-how over a wide range of professionals inside and outside of corporations. Such complex tools have to be system-designed with built-in interim modularity for pre-architecture search and post-architecture finetuning. 相似文献

eGov (eGovernment/eGovernance) is a complex endeavor involving many actors, ambitions, and perspectives. The field has, in research and in practice, over the years expanded its focus from service orientation to a comprehensive perspective with the ambition to integrate all of government in coherent action. Comprehensive integration requires a future-oriented perspective so investment is made in robust and flexible solutions meeting not only today's demands but also sustainable to meet those of the future. This paper addresses the use of the sustainability concept in eGov research. We discuss definitions and elements of sustainability and conduct a structured review of eGov literature investigating how various sustainability areas (social, economic, environmental and technical) are addressed. We find 21 overall themes in 94 papers, with the highest number in the “social” category. Two cross-cutting themes to which 21 overall themes relate are also identified; Decision-making and Infrastructure. Findings show that sustainability is mainly addressed narrowly, focusing on projects rather than general issues, and shallowly with a focus on single factors rather than the complex interaction among them, and with little foundation in sustainability theory. The paper contributes with an overview of themes in previous research as well as theory-based input for future research efforts on eGov sustainability, from a dynamic and sociotechnical sustainability perspective. 相似文献
