Technology systems and technology policy in an evolutionary framework
提出一个技术政策的演化理论，并将其与创新系统文献联系起来。通过分析技术的知识、技能和人工制品三个维度，探讨其多样性生成机制、选择过程和制度结构，为政策制定提供理论基础。
The central purpose of this paper is to outline an evolutionary theory of technology policy and to connect it with the emerging literature on national systems of innovation. Any understanding of technology policy must be based on a clear understanding of the nature of technology and the important differences between science and technology. Technology can be treated in terms of knowledge, skills and artifacts and in each case there are different variety-generating mechanisms, different selection processes and different institutional structures. For policy purposes, the degree of connection between these different dimensions of technology is at the core of technology policy.
