size-wise是什么意思：）请教

出处：China maintains the highest relative importance, size-wise, in the world steel and ferroalloys industries and tremendously influences the ferroalloys  market, as well as its raw materials.

希望能帮忙翻译一下，并举例子：）

Just try:
中国在世界钢铁合金领域继续保持举足轻重的地位，并对铁合金市场和原材料市场具有重要影响力。
In my opinion, size-wise means relatively big in size or take a great percentage. hehe, just for your reference.
