依据零部件产品贸易数据,作者采用了依存比率的方法对亚洲主要零部件产品依存关系进行了研究,结果发现,亚洲主要零部件产品的依存关系分为三个梯度,第一梯度主要依赖中国和日本;第二梯度主要依赖韩国、新加坡、中国香港;最后一个梯度是东盟其他国家和印度。按区域分亚洲主要零部件产品依赖亚洲和欧洲,很少有零部件产品依存北美。同时,用引力模型实证得出影响亚洲零部件产品依存度的主要因素是该国或地区的GDP、外资净流入、签订且生效的区域贸易协定数量(RTAs)。
According to the trade data of parts and components, the author studied the dependencies of the main components and parts in Asia by adopting the dependency ratio method. The results showed that the dependencies of the main parts and components in Asia are divided into three gradients, the first gradient mainly depends on China and Japan; the second gradient relies mainly on Korea, Singapore, Hong Kong, China; the last gradient is the rest of ASEAN and India. By region divided Asia’s major components products rely on Asia and Europe, very few parts dependent on North American products. At the same time, we use the gravity model to conclude that the main factors influencing the dependence degree of parts and components in Asia are the GDP of the country or region, the net inflow of foreign capital and the number of RTAs that are signed and effective.
