This means that over time, the advantage of moving toward freer trade grows dramatically bigger: the $120 billion benefit in 2015 grows to many trillions of dollars of annual benefits by the end of the century. And the benefits would increasingly accrue to the developing world, which would achieve the biggest boosts to growth rates.
这就意味着随着时间的推移，迈向更自由贸易的优势也与日俱增：2015年时1200亿美金的年收益到本世纪末将会达到数万亿的规模。而这些收益会更多地产生在发展中国家，从而实现对经济增长率的最大推动。
