问题如下：
Which of the following statements is associated with the benefits that the country can get from international trade?
选项：
A.Countries receive lower prices for their exports and pay higher prices for imported goods.
B.Industries may experience greater economies of scale.
C.If a country has no absolute advantage, then it can not benefit from trade in the long term.
解释：
B is correct.
As companies enter into new markets for their products,they may gain from economies of scale because the average cost of production declines.
考点：Benefits and Costs of International Trade
解析：参加国际贸易的国家可以以高于本国市场的价格出口商品，而已低于本国的价格进口商品，所以A选项刚好说反了，错误。
出口的行业会进一步扩大生产，从而产生规模效应，进一步降低生产成本，B选项正确。
即便一国没有绝对优势，但是具有比较优势，该国就可以从国际贸易中获取好处，所以C选项错误。
答案里说参加国际贸易的国家可以以高于本国市场的价格出口商品，而已低于本国的价格进口商品 为什么会这样 这样不是x变小m变大了吗 出口量减少 进口量增加 因为外国的东西即进口商品便宜都去买进口商品
