基于百度指数的东南亚国家网络关注度区域差异

基于2010―2013年中国31个省、自治区和直辖市对东南亚10个国家网络关注度的百度指数，采用弹性系数、泰尔指数和相对网络关注度测度方法，从“信源”“信宿”和“信道”3个角度对网络关注度区域差异特征进行了分析，发现：1）中国对东南亚国家关注度普遍提高，东南沿海地区普遍高于内陆地区，长三角地区关注度增长迅速，珠三角地区关注度最高。2）泰尔指数整体下降明显，东、中、西和东北经济分区区内部关注度差异的缩小与区域间关注度差异的拉大并存。3）区域内部的差异是造成中国对东南亚国家关注度差异的主要原因，而东部省份之间的区域差异是造成区域内部差异的主要原因。4）马来西亚逐渐取代越南，与新加坡、泰国组成东南亚地区被中国关注最多国家中的前三甲，出境旅游、经济贸易往来以及金融投资与合作是拉近双边关系的重要因素。5）对东南亚国家相对关注度较高的地区向东南沿海集中，东南亚被关注国家均分布在南海周边，南海战略地位突显。上海与东南亚国家的联系逐渐弱于广东，表现出广东在对东南亚贸易方面突出的地位以及城市之间跨流域的区域贸易分工。

Regional Disparity in the Network Attention of China to Southeast Asia Based on Baidu Index

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.
