中文摘要：

该文首先总结了三螺旋理论中大学、企业、政府三类创新主体在全球科技创新中心形成过程中的作用,并借鉴创新生态系统理论解析各创新主体和要素的特征以及创新环境的重要性。进而以硅谷为例,从实践上深入探究这一独特、高效且持续引领创新发展的全球科技创新中心的建构过程和机理。研究认为硅谷创新体系的形成是各种创新主体、要素与创新环境良性互动的结果,其中世界一流的研究型大学、＂引擎＂企业、奋发有为的政府是硅谷形成的主要驱动因素,密集的风险投资、大量的专业性服务机构、各种行业协会和非正式社交网络为重要的支撑要素并催化各类创新活动的产生,完善的创新基础设施和开放包容的文化环境孕育了硅谷持续创新的土壤。

英文摘要：

Summary and refine function of university,enterprise and government in the process of construct global science and innovation technology center based on triple helix theory,and reference innovation ecosystem theory to resolve the characteristics of innovation subjects and elements and the importance of innovation environment.Then take Silicon Valley as an example,explore the construct process and mechanism of global science and technology innovation center.Research suggests that the formation of innovation system in Silicon Valley is a virtuous interact result of varies innovation subjects,innovation elements and innovation environment.The world first-class research university,＂engine＂company and enthusiastic government are main driving factors in Silicon Valley,cluster of venture investment,a large number of professional services,a variety of industry associations and informal social networks are support factors and produce all kinds of innovative activities,perfect innovation infrastructure,open？and？inclusive culture environment cultivate continuous innovation vitality.
