上海世博交流影响力的网络模型

基于上海世博会对世界人民之间交流的影响力评价问题,建立了以国家和上海世博会为结点的网络模型,定义了世博交流影响力和未与中国建交的国家参展的交流影响力.分析显示:世博交流影响力随各参展国的投入和参展国数目的增加而增大;没有世博结点的网络交流状态越好,上海世博会的影响力越小.最后,通过数值算例验证上述结论.

Network Model of Shanghai Expo's Impact on Communication

This paper studies the way to evaluate Shanghai Expo’s impact on the communication of the worldwide people.By developing a network model with a node standing for Shanghai Expo,we define the Expo’s impact on communication and the impact of the participation of the countries without diplomacy relationship with China.It shows that Expo’s impact on communication increases as the cost of each country and the total number of countries participating Expo increase.While the Expo’s impact decreases as the communication state of the world network turns better.In the end,numerical examples verify the theoretical results.
