基于百度指数的成渝城市群网络联系格局研究

摘要

Network connection structure of cities was analyzed by Baidu Index,which people used in the network for search.Baidu Index of Chengdu-Chongqing agglomeration of China was gotten from http://index.baidu.com in 2011--2014.There are 14 cities in the agglomeration,and Baidu Index between every two cities formed 14 × 14 matrix.The matrix was input a soft Ucinet 6.0 about social network analysis.The netdraw is modular in Ucinet 6.0 and it can be used to analyze the network connection.The urban network connection of Chengdu-Chongqing agglomeration with can be researched by netdraw and dominant flow analysis.The conclusion shows that.(1)From connection netdraw of the Baidu Index,core city is Chongqing and Chengdu in the urban agglomeration.The others are periphery cities.(2) From dominant flow perspective,Chengdu is the dominant city;Chongqing is the second dominant city and the others are subordinated cities in the urban agglomeration.The network structure of Chengdu-Chongqing urban agglomeration in China is "one dominant city,one second dominant city and some subordinated cities".%利用城市居民在网络搜索中的百度指数分析城市网络联系格局,从百度指数网(http://index.baidu.com)上得到2011-2014年成渝城市群14个城市两两间的百度指数,建立14x14的多值矩阵并导入社会网络分析软件,采用NetDraw和优势流分析法研究成渝城市群网络联系格局.结果表明:(1)NetDraw分析表明成都和重庆在成渝城市群网络联系中为核心城市,其他城市为边缘城市.(2)从优势流分析看,成都为成渝城市群中的主导城市,重庆为次级主导城市,其他城市为从属城市.总体而言,成渝城市群形成了“一主一次多从”的网络联系基本格局.
