We examine how the structure of the world trade network has been shaped by globalization and recessions over the last 40 years. We show that by treating the world trade network as an evolving system, theory predicts the trade network is more sensitive to recessionary shocks and recovers more slowly from them now than it did 40 years ago, due to structural changes in the world trade network induced by globalization. We also show that recession-induced change to the world trade network leads to an increased hierarchical structure of the global trade network for a few years after the recession.
我们研究了过去 40 年来，全球化和经济衰退如何塑造世界贸易网络的结构。我们表明，通过将世界贸易网络视为一个不断演变的系统，理论预测贸易网络对衰退性冲击更加敏感，并且现在从冲击中恢复的速度比 40 年前要慢，这是由于全球化导致世界贸易网络的结构发生了变化。我们还表明，衰退引起的世界贸易网络的变化会导致全球贸易网络在衰退后的几年内呈现出更高的层级结构。
