请问如果题目中如果给的是一个商品需要多少劳动力的话,怎么分析?能举个例子嘛,是不是先要换算回来,换成一个劳动力生产几个商品,再进行比较?

Comparative advantage
Definition
If two countries have different opportunity cost of producing goods, each will have a comparative advantage in some goods, and trade will increase the total production and consumption possibilities in both countries, improving economic welfare.
How to determine
A: 10X=5Y→ opportunity cost of 1Y is 2X;
B:9X=3Y→ opportunity cost of 1Y is 3X;
For product Y, country A has the lowest opportunity;
Thus, A produces Y, and B produces X, and then trade each other
