Abstract: Introducing the concept of “social technology”, which is dividing into three levels, to analyze the transitional process of science and technology park from the perspective of co-evolution of the physical technologies and social technologies. Considering the diverse developing models and paths for international science and technology park, which including market-driven, community-driven and government-driven, this paper selected three typical international park as the sample parks, studing the dynamic and mechanism in transition from “Catching up” to “Leading the way”, from “External-driven” to “Internal-driven” and from “import-driven” to “Innovating independently”. Then, exploring the experience and modes, summaring the similarities and differences in transition, which are valuable practical and theoretical enlightenment to our country’s science and technology park transition.
