摘要:

根据城市统计中存在大量属性数据的特点,基于无尺度网络方法,根据2002~2014年中国城市医疗统计数据变化的相似性来建立城市之间的联系,得到中国城市医疗软件网络和硬件网络。在对两个网络对比和测试分析后得到:中国城市医疗网络是由20%高度城市代表的具有圈层聚类结构的无尺度复杂网络。中国城市医疗硬件网络比软件网络复杂和稳定。中国城市医疗网络的结构和功能主要由强关系城市决定,弱关系城市对网络没有实质影响。可见,以无尺度网络方法来分析城市网络可以发现很多隐藏的问题。

Abstract:

According to the characteristic of large amounts of attribute data in urban statistics, this paper uses the scale-free network method to get the networks of urban medical software and hardware in China, which is based on the similarity of changes in medical statistics from 2002 to 2014. After comparing and analyzing the two networks, the conclusions can be drawn: 1) China's urban medical networks are scale-free complex networks with circle cluster structure represented by 20% of high-dgree cities. 2) Chinese urban medical hardware networks are more complex and stable than software networks. 3) The structure and function of China's urban medical networks are mainly determined by strong relationship cities, and weakly related cities have no real impact on it. It can be seen that analyzing the urban network by the scale-free network method can find many hidden problems.

Key words: scale-free networks, urban medical network, China
