Abstract: With the development of Economic Geography, the effects of Internet for city networks are turning into a new and hot topic. In this study, the mid-Yangtze urban agglomeration was selected as an example and attention data of year 2011 and 2014 between cities were obtained based on "Degree of Consumer Attention" function provided by Baidu.com. The results showed that the structure of cities in this region stands in a shaping stage. The grade of cities becomes increasingly clearer and the differences are more obvious. The polarization effect and diffusion effect are in coexistence in three sub-urban-agglomerations. Internet has a tendency of adjusting and revamping the current structure, instead of overthrowing it totally, which is believed to be a good opportunity for some developing cities to change their positions. Combining the traditional industry and internet, with the direction of development of the division of labor, some developing cities are stepping into the way of changing their traditional structure of city network.

Key words: baidu index, city network, information flow, Middle Yangtze Urban Agglomeration
