摘要:This paper discusses the results of the application of Jones' Inequality to the n-country, m-good Ricardo–Graham model. In the Jones' Inequality model, the number of countries is the same as the number of goods produced. On one hand, if a country is divided into regions for the purposes of this model, Jones' Inequality can be applied to the case where the number of goods is larger than the number of countries. On the other hand, when two or more countries specialize in the same good, the model distinguishes the same good as being a different commodity for the other countries.
