经济学概念:供给曲线

The Supply Curve

泰勒 ·考恩 阿历克斯·塔巴洛克
供给曲线
我们了解需求曲线是怎么回事
– [Narrator] Now that we’ve gotthe demand curve down,
那让我们来看下供给曲线吧
let’s move on to the supply curve.
供给曲线表示货物供应商
A supply curve shows how muchof a good suppliers
在不同价格下想要或能够供货多少
are willing and able to supplyat different prices.
与需求曲线一样
As with the demand curve,
每种商品和服务对应一条供给曲线
there’s a supply curve for every good and service.
道理都是一样的 那么
And again the ideas are the same, so let’s
我们来看石油的供给曲线
look at the supply curve for oil.
我们可以看出价格和
We see an intuitive relationshipbetween price
与供给数量有关
and the quantity supplied.
随着价格上升
As the price goes up, the quantity of oil
公司愿意供应的石油量就增加
that companies are willingto supply increases.
这种情况下 假设每桶油5美元的低价
In this example, in a low price,$5 per barrel,
每天供应1千万桶油
let’s say 10 million barrelsof oil are supplied per day.
当每桶20美元 就有2500万桶油供应
At $20 per barrel,25 million barrels are supplied,
当每桶55美元 就会有五千万桶油供应
and at $55 per barrel,50 million barrels are supplied.
总的来说 更高的价格意味着更多的供应量
So in general, a higher pricemeans a greater quantity supplied.
让我们深入探究一下为什么吧
Let’s delve deeper and see why.
虽然石油遍布世界 但开采难度却不尽相同
Oil exists all over the world, but it’s not equally easy to extract.
一些地方 像沙特阿拉伯
In some places like Saudi Arabia,
很容易就能从地表开采石油
it’s really easy to get oil out of the ground.
开采一桶石油大约要2美元
It costs about $2 a barrel to extract.
而美国 像阿拉斯加州 石油埋藏更深
Oil in the US, like from Alaska,is a lot deeper
在开采上花费更多 每桶油至少要10美元
and getting it out cost more,at least $10 per barrel.
用钻机开采石油 像海湾边的
And producing oil from an oil rig,like the Atlantis rig
亚特兰蒂斯钻机甚至更加昂贵
in the Gulf Coast,is even more expensive.
钻机至少要下到水下一英里以上
That rig has to descendmore than a mile underwater
才能开始挖掘
before drilling even begins.
当油价相对低的时候
When oil prices are relatively low,the only suppliers
盈利的就只有那些有低价油的供应商
that can turn a profit are those who can get to the oil cheaply,
像沙特阿拉伯
like Saudi Arabia.
随着价格上升 开采成本更高的供应商
As the price goes up,other suppliers in Nigeria, Russia,
像尼日利亚 俄罗斯 阿拉斯加
and Alaska, who have higher extraction costs,
只有通过技术盈利才能进入市场
start to become profitable so they can enter the market.
价格更高时 甚至使用最贵的开采技术
As the price gets higher, even the most expensiveextraction techniques
都能够盈利
become profitable.
供给曲线向上倾斜是因为
The supply curve slopes upward because the only way the quantity
石油价格上升的唯一原因就是
of oil can be increased is to exploit higher and higher
越来越高的石油原料开采费用
cost sources of oil.
随着石油价格的上升
As the price of oil goes up,
油井的开采就更深
the depth of the oil wells goes down.
通过这个简单的供给曲线
With this simple line the supply curve summarizes
就能表现出供应商对价格变动的反应
the way suppliers respond to a change in price
这包括供应商怎么依据价格
including how suppliers will enter and exit the market
进入和退出市场
depending on the price.
到现在 我们讨论了如价格下降
So far, we’ve said things like if the price goes down,
买家会买更多或是如价格上升
buyers will want to buy more or if the price rises,
供应商想卖出更多商品
suppliers will want to sell more.
但是我们还不了解如何决定价格
But we haven’t said anything about how prices are determined.
这也是下个视频的主题 平衡价格
That’s the subject for the next video, Equilibrium.
