A Comparative Study on the Geo-influence of China and the U.S.on Southeast Asia from the Perspective of Multiple Fields
Southeast Asia is an important geostrategic region for China and the U.S..This paper builds a geo-influence evalua-tion model based on the geo-influence analysis framework,and quantitatively depicts the evolution characteristics and driving mechanism of the geo-influence of China and the U.S.on Southeast Asian countries from the perspectives of politics,economy,and military fields.It is found as follows.① From 2010 to 2021,China's geo-influence on Southeast Asia showed an upward trend,and its geo-economic influence had the fastest rising trend,and the influence in both political and economic fields gradually surpassed that of the U.S..The geopolitical influence of the U.S.on Southeast Asia was relatively stable,its geo-economic in-fluence showed a slow growth,and its geo-military influence had obvious advantages over China,but the gap was narrowing.At the same time,there were great differences between the two countries in the geo-influence on each country in different fields.②National strength is the cornerstone of geo-influence,but national strength does not maintain a strict positive correlation with geo-influence.Geo-relationship interaction is the core variable of geo-influence,and interaction events in different fields are its specific external manifestations,which can be used as one of the elements to consider the geo-influence in different fields.Do-main relationship is an important variable that cannot be ignored in evaluating geo-influence.Geographic location,traffic condi-tions,cultural distance,etc.have a restrictive effect on geo-influence,and closer distance,convenient transportation,strong cul-tural identity,etc.are conducive to enhancing geo-influence.
