基于文献引证的国际知识流动影响因素探究

Research on influencing factors of international knowledge flow based on citation relations

基于全球52个样本国家和地区的引文数据,从个体和国家对两个视角探析了国际知识流动的内在机制,并且采用负二项回归模型检验了影响国家知识流动表现和国家间知识流量的关键因素。研究结果表明：（1）不同时滞条件下本国的国际合著行为对知识流动表现的影响存在差异;（2）国家间的知识势差、知识相似性、科学家流动量、科研合作强度、关系的网络位置都是影响知识流量的重要因素,且存在国家间关系的网络位置-知识势差-知识流量的作用路径。因此,中国参与全球知识流动需要不断利用知识相似搜寻潜在伙伴、人才流动等过程中的有利条件构建科研合作关系,同时基于网络位置相近搭建国家间知识互动平台辅助提升知识势差对跨国知识流动的促进作用。

Based on the citation data of 52 sample countries and regions around the world,this paper analyzes the internal mechanism of international knowledge flow from two perspectives of individuals and pairs of countries; and then uses the negative binomial regression model to test the key factors influencing the performance of national knowledge flows and the inter-country knowledge flows. The results showed that：（ 1） the effect of international cooperation on national knowledge flow performance under different time-lags is different.（ 2） Knowledge gap,knowledge similarity,international mobility,collaboration strength and network location of inter-State relations are all important factors affecting inter-country knowledge flows. And there is a path of action,that is,the network location of inter-State relations-knowledge gap-knowledge flow. Therefore,when China participates in the global knowledge flow,on the one hand,it needs to continuously establish the scientific and research cooperation relationship,utilizing favorable conditions in the process of searching for potential partners based on knowledge similarity and the flow of talent; on the other hand,it should build up the knowledge exchange platform between countries based on the similar network locations to help promote knowledge gap positively affects international knowledge flow.
