问题如下：
In the Heckscher–Ohlin model, what will happen as a country opens up to trade?
选项：
A.It will have a favorable impact on the scarce factor and a negative impact on the abundant factor.
B.It will have a favorable impact on the abundant factor and a negative impact on the scarce factor.
C.The price of the export good decreases and the price of the import good increases.
解释：
B is correct.
When a country opens up to trade, the abundant factor gains more relative to the scarce factor in each country. This result is because trade causes the price of the export good to increase and the price of the import good to decline.These price changes affect the demand for factors used to produce the import and export goods,and hence affect the incomes received by each factor of production.
考点：Heckscher–Ohlin model
根据HO模型，一国资源禀赋丰富的具有比较优势，比如一国劳动力资源丰富，那么该国就应该出口劳动密集型产品，发展劳动密集型产业。那么劳动力在该国就会被大量需求，劳动力就能获得更高的生产报酬分配。相反该国资本资源稀缺，那么它就从外国进口资本密集型产品，发展资本密集型产型。资本要素在该国就不受待见，不仅受到进口品的冲击，能够分的的生产报酬也比较少。所以B选项正确，A选项错误。
C选项是一个打酱油的选项，HO模型并没有此结论。
如上，如果是进口国，那本国资源稀缺情况下进口价格高那反而是不好；如果本国资源比较充足的情况下出口，那么出口价格低对自己来说不是不好的么
