其实题目的大概描述是：运用辩证观来解释 捐献是有利于产业的内部交易的。可是这里会涉及到几个理论呢？

上面的解释我错了， 其实是说捐献（endoments ） 可以带给区域中产业好处。

我找了很多资料。。其中有个叫做H/O theory 。 Heckscher-Ohlin

In a model in which each country produces two goods, an assumption must be made as to which industry has the larger capital-labor ratio. Thus, if the two goods that a country can produce are steel and clothing, and if steel production uses more capital per unit of labor than is used in clothing production, then we would say the steel production is capital-intensive relative to clothing production. Also, if steel production is capital intensive, then it implies that clothing production must be labor-intensive relative to steel.

Another realistic characteristic of the world is that countries have different quantities, or endowments, of capital and labor available for use in the production process. Thus, some countries like the US are well endowed with physical capital relative to their labor force. In contrast many less developed countries have very little physical capital but are well endowed with large labor forces. We use the ratio of the aggregate endowment of capital to the aggregate endowment of labor to define relative factor abundancy between countries. Thus if, for example, the US has a larger ratio of aggregate capital per unit of labor than France's ratio, we would say that the US is capital-abundant relative to France. By implication, France would have a larger ratio of aggregate labor per unit of capital and thus France would be labor-abundant relative to the US.

可我有个问题， endowments 怎么和capital 联系起来呢？

a good explanation 怎么翻译成了“有利于”？

题目的意思是：

由factor endowments(要素禀赋)引起的Comparative advantage （比较优势）来解释inter-regional trade（区域间贸易）的发生。

先学好英语吧，不然怎么看文献。。。。
