Abstract:

The network attention is an important indicator to measure the level of links between China and the countries in Southeast Asia. Based on Baidu index of network attention in 31 provinces, autonomous regions and municipalities in China during 2010-2013, using coefficient of elasticity, Theil index calculation method and comparative network attention, from the perspectives of “information source”, “information sink” and “information channel”, this paper analyzes the characters of the regional disparity in the network attention of China to the countries in Southeast Asia. It is found that: 1) the network information of the countries in Southeast Asia is gaining more and more attention. However, in China the attention in southeast coastal areas is much more obvious than that in inland areas. The attention that the public in the Yangtze River Delta pay to Southeast Asia countries increases rapidly, and that in the Pearl River Delta has been the most; 2)The Theil index of all the administrative regions at provincial level is showing a downward tendency obviously, the attention difference inside the region is decreasing while that between regions is increasing; 3)The regional disparity in China is the main reason to cause the attention disparity of the provinces to the Southeast Asia countries; 4）In place of Vietnam, Malaysia, Singapore and Thailand have become the top 3 in Southeast Asia that attract the most attention from China. The development of tourism, trade and financial investment is the important factor to promote the cooperation between China and those countries. 5) The regions in China which pay more attention to Southeast Asia are distributed in the southeast coastal areas, and the countries in Southeast Asia focused by China are more distributed around the South China Sea. So the strategic position of the South China Sea is becoming increasingly important. The closest links are between the Yangtze River Delta, the Pearl River Delta, the Beijing- Tianjin-Hebei region and the countries in Indo-China Peninsula. In comparison with Shanghai, Guangdong has closer link with the countries in Southeast Asia, playing an important role increasingly in Trade to those countries.
