“一带一路”沿线国家科技合作网络演化研究

Study on scientific and technological collaboration network evolution of countries in one belt one road area

利用Incopat专利信息平台检索2002-2016年"一带一路"沿线国家PCT专利合作申请数据,以3年为间隔将这15年分为5个阶段,构建各阶段科技合作网络,利用社会网络分析方法探索网络整体结构、核心节点、拓扑结构及高频合作对的演化过程。研究发现:(1)网络发展仍处于初级阶段。(2)俄罗斯在前4个阶段网络中始终位居绝对核心地位,但在第5阶段网络中被中国超越;网络围绕核心节点聚焦的程度基本呈现逐渐减小的趋势。(3)网络已逐渐形成较为稳定的2类结构:以俄罗斯为中心的星型结构和由中国、俄罗斯、新加坡、以色列等经济实力较强的沿线国家组成的网状结构;网络中的高频合作对高度集中。

Using PCT patent application cooperation data between countries alongside One Belt and One Road Area during the period of 2002-2015 from the Incopat patent information search platform,this paper divides the fifteen years into 5 stages,constructs scientific and technological collaboration network for each stage,and analyzes the whole structure,key points,topological structures and pair of high frequent cooperation of each network.The research shows that,firstly,the development of network is still in its infancy,the development trend is not stable;secondly,Russia and China are the key points in the networks,Russia is the most important point in the first four networks and China takes its place in the network of last stage,the extend of focusing on the key points of the whole network has showed the declining trend;thirdly,there are 2 kinds of topological structures,which are the star topology with the center of Russia and a network topology consisting of several relatively rich countries,and the pairs of high frequent cooperation are quite few.
