The world-trade multiplier, though less widely recognized, helps to explain why the growth deceleration has been so widespread and persistent. When a country’s economic growth slows, it imports less from other countries, thereby reducing those countries’ growth rates, and causing them, too, to reduce imports.
世界贸易乘数没有被如此广泛地认识到，但它有助于解释为何增长减速如此普遍、如此持久。当一国的经济增长放缓时，它的进口会有所减少，从而影响出口国的增长率，并导致它们也减少进口。
