基于GDELT新闻大数据的东南亚地缘交互关系制图研究

Geo-interaction Relation Mapping in Southeast Asia Based on News Big Data in GDELT

地缘关系研究是地理学中的一个重要研究领域,基于大数据的地缘关系的定量研究是对传统定性地缘关系研究的必要补充。利用全球事件、语言与语调(global database of events,language,and tone,GDELT)新闻数据库获取中国与缅甸、老挝、越南、泰国和柬埔寨5个国家之间的交互事件,通过定量统计和空间制图、构建交互网络、时空热点分析等方法,对中国与这5个国家的地缘关系进行剖析。并以中缅为例分析两国地缘关系变化的原因,提出相应合作建议。结果表明,事件主要发生在各国政治经济文化较为活跃的地区;中国与越南和泰国的地缘交互较多,与越南的关系最为复杂;中国与五国的交互热点主要分布于越南、泰国、柬埔寨,除越南外,中国与另外4个国家的合作水平呈增强态势。

Geo-relation research is an important research field in geography.The quantitative study of geo-relation based on big data is a necessary supplement to traditional qualitative geo-relation research.We use a news database called global database of events,language,and tone(GDELT)to obtain interactive events between China and 5 countries:Myanmar,Laos,Vietnam,Thailand and Cambodia.Through quantitative statistics and spatial mapping,the construction of interactive networks,spatiotemporal hot spot analysis and other methods,we analyze the geo-relations between China and these 5 countries.We choose China and Myanmar as the example to analyze the reasons for the changes in the geo-relations between them,and put forward corresponding suggestions for their cooperations.The conclusions are as follows:the events mainly occur in the regions where the politics,economy and culture are active.China has more interactions with Vietnam and Thailand,and the relation between China and Vietnam is complex.The hot spots of interactions between China and these 5 countries are mainly distributed in Vietnam,Thailand and Cambodia.Except for Vietnam,the levels of cooperations between China and the other four countries are increasing.
