中文摘要：

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14×14的多值矩阵并导入社会网络分析软件,采用Net Draw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）Net Draw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。

英文摘要：

Network connection structure of cities was analyzed by Baidu Index, which people used in the net- work for search. Baidu Index of Chengdu-Chongqing agglomeration of China was gotten from http ：//index. baidu. corn 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 agglom- eration with can be researched by netdraw and dominant flow analysis. The conclusion shows that. （1）From connec- tion netdraw of the Baidu Index, core city is Chongqing and Chengdu in the urban agglomeration. The others are pe- riphery 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＂.
