本文以中美两国为例,建立了一个简单的单一要素的两商品模型,并着重分析了在自由贸易状态下中国技术进步给中美两国带来的影响:如果中国的技术进步发生在其出口部门,这将同时提高两国的福利;然而,如果中国的技术进步发生在美国的出口产品领域,那么美国将遭受永久性的利益损失。 Taking China and the United States as examples, this paper establishes a simple two-product model with single factor and focuses on the impact of China’s technological progress on China and the United States in the context of free trade: If China’s technological progress occurs in Its export sector, which will at the same time raise the welfare of both countries; however, if China’s technological advancements occur in the area of ​​U.S. exports, then the United States will suffer a permanent loss of profits.
