Competition or Complementarity? An Empirical Study on Economic Relationship among “BRICS”

本文运用贸易结合度指数、显性比较优势指数、斯皮尔曼等级相关系数、贸易互补性指数等多种贸易指数研究了"金砖国家"内部贸易关系的紧密程度、贸易的竞争与互补性状况,发现金砖各国之间的贸易关系并不紧密,总体上看金砖国家之间存在贸易互补,但也有较强的贸易竞争,即使高度互补的产品在不同市场上也存在着不同程度的竞争。随着"金砖国家"合作机制的深化,各国将会在合作中进行竞争,在金砖国家内部将会出现资源的再分配和利益的再整合过程。
