This paper proposes a classroom experiment to illustrate the specific-factors model. In it, students act as decision-makers in an economy comprising two goods and three factors, and each is asked to maximize the value of marginal production by allocating his/her labor force between the two sectors. Through trading products, all players work as a whole economy in pursuit of higher welfare. From their individual perspectives, they can observe the impacts of relative price changes and international labor mobility on productivity and income distribution. The group perspective, meanwhile, reveals the gains arising from trade and welfare. Together with discussion of theoretical predictions, experimental results and case studies, this classroom experiment could foster better learner understanding of the specific-factors model, both individually and collectively.

本文提出了一个课堂实验来说明具体因素模型。在其中，学生扮演着一个由两种商品和三个因素组成的经济体的决策者，并要求每个人通过在两个部门之间分配劳动力来最大化边际生产的价值。通过交易产品，所有参与者都在整体经济中追求更高的福利。从他们的个人角度，他们可以观察到相对价格变化和国际劳动力流动对生产率和收入分配的影响。同时，团体视角揭示了贸易和福利带来的收益。结合理论预测，实验结果和案例研究的讨论，该课堂实验可以帮助学习者更好地理解具体因素模型，
