基于专利合作申请数据分析的加权网络研究

Analysis of weighted network research based on patent application for data

基于电子信息类部分企业专利合作申请的数据构建了加权合作网络,针对加权合作网络中边权值分布和点强度分布呈现的厚尾效应和幂率特征的问题,通过对网络的动态演化结构参数和统计特征进行分析构建了一种新的加权合作网络模型。从理论分析和数值仿真实验两方面对该模型进行了分析和研究,证明了该模型的科学性,实验结果出现了与现实网络一样的厚尾和幂律特征。结合现实网络给出了电子信息类的部分企业合作现状及其原因分析,为该行业以后的发展提供一些参考。

The weighted cooperative network was found based on the data of patent cooperation in electronic information.According to the thick tail effect and power-law characteristics presented in the edge weight distribution and strength distribution in the weighted cooperative network,this paper constructed a new weighted cooperative network model through the analysis of the parameters of dynamic network evolution structure and statistical characteristics.This paper analyzed and studied the model from two aspects of theoretical analysis and numerical simulation,of which the scientific nature was proved.There existed the same thick tail and power law characteristics as the real network in the experimental results.Combining with the reality network,it shows the current situation and the reason analysis of the cooperation of some enterprises,which provides some reference for the future development of the industry.
