Tech Clusters
回顾了科技集群的构成、内部运作机制以及政策能否有意培育它们，并讨论了先进技术对传统行业的影响、集群面临的压力与反弹，以及未来的研究问题。
Tech clusters like Silicon Valley play a central role for modern innovation, business competitiveness, and economic performance. This paper reviews what constitutes a tech cluster, how they function internally, and the degree to which policy makers can purposefully foster them. We describe the growing influence of advanced technologies for businesses outside of traditional tech fields, the strains and backlash that tech clusters are experiencing, and emerging research questions for theory and empirical work.
