| 摘 要： | 选取我国省域网络学术信息截面数据,在考虑地理空间因素的情况下,建立网络学术信息空间分布影响因素计量模型,以定量的方法对形成我国网络学术信息空间分布格局的原因进行分析。研究发现,网络学术信息的空间分布存在空间依赖性,空间误差模型是进行该分析的最优模型,经济发达程度、科研队伍大小、网络发展水平、人口基数和城市居民数量是影响网络学术信息空间分布情况的主要因素。

| Abstract: | According to the sample collected by search engines,the Spatial Error Model(SEM),considering spatial dependence of academic information on Internet is established,which is a quantitative method to analyze the spatial agglomeration phenomenon of academic information on Internet.It is found that spatial dependence exists and SEM is the best model when analyzing this problem.Five factors are main influence factors of spatial distribution of academic information on Internet,and they are economic development lev... |
