请教OG 13 passage 2 的一句话。

猴子酸奶

Even a vastly more ecoefficient industrial system could, were it to grow much larger, generate more total waste and destroy more habitat and species than would a smaller, less ecoefficient economy .

请问这句话中的“were it to grow much larger" 在这里是什么用法，第一次见到，是省略的虚拟吗？

虚拟语气：如果它成长的更壮大的话。
