简介：As a result of the international division of labor, the trade value distribution on different products substantiated by international trade flows can be regarded as one country’s strategy for competition. Each country wants to diversify their investments on different products as well as make profits as possible as they can. We build a model based on maximum entropy principle to reproduce the distribution curves of countries. The results show that almost all countries' export share distributions can be explained by the maximum entropy model if the constraints are properly selected.

我们可以将每个国家在不同产品上的出口份额看作是一种面向国际市场的劳动分工策略。每个国家都在尽量多样化自己的出口多样性的同时牟取最大的经济利益。本文提出了一个最大化熵模型以解释各个国家在不同产品上的出口份额分布曲线。在合适地选择了最大化熵的约束条件后，我们成功地用一个单参数最大熵模型较好地拟合了100多个国家的出口分布曲线。
