Question

英语翻译
That would,in turn,increase the volume of world trade over and above that resulting directly from high growth.
这个over and above 还有high growth事导致的结果还是原因？

Answer 1

反过来,那（指前文）将会增加世界贸易量并超出由（经济）高增长直接带来的数值（贸易量）.
over and above 表“超出,在.之外”
high growth不表结果或原因.这里是做了个比较,即,现在的贸易量超出了之前由高增长所带来的贸易量,第二个“that”是代词,指代the volume.
