收入法计算GDP时，如果生产的产品没卖完，有存货，怎么算是收入呢？

在用收入法计算GDP的时候，存货也计算在内吗？
收入法计算GDP计算的是要素收入，生产存货这部分产品时使用了原材料和劳动力，并支付了相应的租金或工资，所以在使用收入法计算GDP的时候就不应该计入存货价值了吧？

但是存货这部分价值增值还是没有通过收入实现啊？ 11# apple4513

在支出法核算国内生产总值时，投资时包含存货投资的。用收入法计算时，虽然存货没有在其中显示出来，但是利润相对来说是有变化的，应该是在利润中体现的。

Imagine that a bakery hires workers to produce more bread, pays their wages, and then fails to sell the additional bread. How does this transaction affect GDP?
The answer depends on what happens to the unsold bread. Let’s first suppose that the bread spoils. In this case, the firm has paid more in wages but has not received any additional revenue, so the firm’s profit is reduced by the amount that wages are increased.Total expenditure in the economy hasn’t changed because no one buys the bread.Total income hasn’t changed either—although more is distributed as wages and less as profit. Because the transaction affects neither expenditure nor income, it does not alter GDP.
Now suppose, instead, that the bread is put into inventory to be sold later. In this case, the transaction is treated differently. The owners of the firm are assumed to have “purchased’’ the bread for the firm’s inventory, and the firm’s profit is not reduced by the additional wages it has paid. Because the higher wages raise total income, and greater spending on inventory raises total expenditure, the economy’s GDP rises.
What happens later when the firm sells the bread out of inventory? This case is much like the sale of a used good.There is spending by bread consumers, but there is inventory disinvestment by the firm.This negative spending by the firm offsets the positive spending by consumers, so the sale out of inventory does not affect GDP. The general rule is that when a firm increases its inventory of goods, this investment in inventory is counted as expenditure by the firm owners.Thus, production for inventory increases GDP just as much as production for final sale.A sale out of inventory, however, is a combination of positive spending (the purchase) and negative spending (inventory disinvestment), so it does not influence GDP. This treatment of inventories ensures that GDP reflects the economy’s current production of goods and services.

能解释下不，太长了 15# haorenza

gdp衡量的是总产出，它是从生产的角度来考虑问题的，物品生产出来后不论是否销售出去，都计入gdp.假设某年度企业总共生产了100单位的物品，只销售了80单位。用支出法核算gdp如果只核算销售出去的80单位，显然gdp只有80单位，少算了20。因此没有销售的算作企业自己的投资20单位。这样加起来刚好是100单位，总支出=总产出。再从收入的角度看，企业使用各种生产要素生产了100单位的物品，要向要素所有者支付报酬（工资、地租、利息、利润），这构成了他们的收入。收入总和也是100单位。即总产出=总收入。物品生产出来后，企业就有了支付的义务，各要素所有者就有了获取收入的权利，而不论物品是否卖掉。例如，企业不能因为物品没有销售出去就不给工人发工资，借钱也要发工资啊。（到资本市场借钱的话，也就如同买下了自己的存货，这样资本市场上的储蓄就转化为企业的投资了。尽管有时是非意愿的投资。）

那企业主呢，卖不出去的产品算存货，计入他的收入吗？

因为gdp衡量的是市场价值，存货也按市场价值计价。市场价值就包含各要素所有者的收入，当然也包含企业主的收入。会计学上有收入实现的概念（比如商品卖出去了，就说收入实现了；没卖掉，没有收入）。而gdp核算的逻辑于此不同，物品只要生产出来了，就认为收入形成了。

应该是支出法。企业自己支出了
