摘要:

知识网络是由创造、转移、吸收和应用知识的行为主体在知识的传播与交流过程中彼此联结而形成的网络结构。以国际ISI和国内VIP数据库中2000~2009年发表于生物技术领域的合著论文作者信息统计数据为数据源,基于社会网络分析的理论和方法,从国际和国内省级层面运用UCINET和Pajek软件分析知识网络的空间极化和扩散规律。总体上看网络仍处于量的扩张期,网络的稳健性正在逐步提高,网络结构开始向成熟型转变。国际层面上看,知识网络的空间极化现象明显。国内层面上看,知识网络由等级结构向扁平结构转变,空间上相应地经历了由一极向多核再向多中心发展的过程。依据知识网络空间分布特征,将知识交流区域分为知识集聚区、知识门户区、知识途径区及知识边缘区四大类型,并对我国的技术创新政策提出对策建议

Abstract:

Knowledge network is a kind of interconnected network that is born in the process of diffusion and communication of knowledge by the actors who create,transfer,absorb and apply knowledge,such as enterprises,universities,organizations and institutions.This paper takes statistical data of the papers published in cooperation about the biotechnology both in the database of ISI (international) and VIP (Chinese) from 2000 to 2009 as data source.Based on the theory and methods of social network analysis,it uses UCINET and Pajek to analyze the spatial polarization and diffusion of knowledge network at international level and at provincial level. Generally,the network is still in the phase of expansion,the robustness of the network is gradually improving,and the network structure changes to mature.At the international level,the spatial polarization of network is evident.At the national level,the structure of network changes from hierarchical to flat,and accordingly the spatial structure of network changes from one pole to muticores and further to muticenters.Based on the spatial distribution of the network,the knowledge exchange area is divided into four types:knowledge accessagglomeration,knowledge gateway, bypass agglomeration and peripheral utilizer.Finally,provide some advice to the government for policy making to improve the technological innovation in China.
