我们在前面提到，为了避免重复计算GNP，只计算在市场上出售的最终商品和服务。那么，GNP中的进口是否也应被定义

为仅仅包括最终商品和服务的进口？出口呢？

We stated in this chapter that GNP accounts avoid double counting by including only the value of final goods and services sold on the market．Should the measure of imports used in the GNP accounts therefore be defined to include only imports of final goods and services from abroad？ What about exports？
