为改变以往研究局限于从学科或地域交叉单一测度探究该跨度对科研协作知识交流影响的做法,本文融合分析学科交叉和地域交叉两个测度对科研协作知识流动元网络特征形成的复杂影响过程。先构建起科研协作知识流动元网络,并设置节点、子群、全网各维度特征分析的指标体系;然后分别根据计算出来的各指标值分析得到元网络特征;再分别从地域交叉和学科交叉两个测度分析得到这两个子网对应的在节点、子群、全网各维度的特征;最后建立起地域交叉和学科交叉子网与科研协作知识流动元网络特征之间的联系,得到学科交叉、地域交叉在科研协作知识流动元网络特征形成演化过程中的作用机理。

To change the practice that previous studies were limited to in exploring the influence of a single measure of discipline or region crossover on knowledge exchange of academic collaboration,this study integrates two measures of such crossovers to analyze the complex influence process of these two measures on the formation of meta-network characteristics of knowledge flow of academic collaboration.First,we construct such a meta-network,and set up an index system for the analysis of the characteristics of nodes,subgroups,and the entire network.We then analyze the characteristics of the meta-netw...
