Returns Tend to Equalize: The Secret of Magic Pig Pills and Taxi Lease Fees 回报率趋同：肥猪丸与出租车份子钱的秘密
This is Suzhou Victory Textile Co., Ltd.
Let’s talk about an economic principle: the returns on all assets tend to equalize.
Start with a pig farm story.
A nutrition professor invents a “magic pig pill.” One pill makes a pig gain 100 jin of meat, at nearly zero cost.
First question: does this pill change society’s real interest rate? No. Interest rates depend on people’s time preference—how patient they are—not on a pill.
Does the pig farm’s profit increase? Yes. 100 jin of extra meat at no cost.
Who gets that extra profit? Mostly the professor. Competition among pig farms pushes the pill’s price toward its marginal contribution—100 jin of meat.
Not all goes to the professor—the farm’s pigs, land, and labor also contribute. But the new gain flows to the scarce resource that made the difference.
Does the pig farming industry’s rate of return increase? No. Returns go up, but rates don’t. Why? Because the pill’s price rises too. Once everyone knows its value, the price adjusts so that the farm’s rate of return falls back to the social average.
That’s the core principle: under competition, any resource’s return approaches its marginal contribution. Returns on all assets tend to equalize.
Now take taxis.
Many say: lower the “daily lease fee” to raise driver income, without raising fares. Does that work?
A taxi ride combines many inputs: car, fuel, driver, and a monopoly license. Your ¥20 fare is just “collected” by the driver—it covers depreciation, fuel, wages, and the license’s “monopoly rent.”
If you force down the lease fee, drivers seemingly earn ¥1000 more. That attracts more people to the job. They’ll pay nearly ¥1000 to get that spot. License owners will then take that ¥1000 back, openly or under the table.
In the long run, cutting the lease fee neither raises driver income nor solves peak-hour shortages.
The solution: let fares float to encourage more supply; open up licensing and use ride‑sharing to mobilize more vehicles.
At Suzhou Victory Textile, from spinning to finishing, every process seeks its own marginal contribution. Resources flow where returns are highest, but competition pulls everything into balance.
Final thought: which yields higher returns—blue‑chip stocks or junk stocks? And why?

今天讲一个经济学原理：所有资产的回报率，最终都会趋向相等。
先从一个养猪场的故事说起。
有个营养学教授发明了“肥猪丸”，猪吃一颗，就能多长100斤肉。成本几乎为零，收益却巨大。
问题来了：这颗肥猪丸，会改变社会的真实利率吗？不会。利率取决于人们的时间偏好——愿意等还是急着要，跟一颗药丸没关系。
那养猪场的收益会提高吗？当然会。多长100斤肉，白赚的。
那这100斤肉的收益归谁？基本归教授。因为竞争——他会把肥猪丸卖给不同养猪场，价高者得。最终，肥猪丸的价格会逼近它带来的边际收益：100斤猪肉。
注意，不是全部归教授，因为还需要猪、场地、劳动力配合。但新增的收益，大部分流向能带来边际贡献的那个稀缺资源。
那养猪业的回报率会因此提高吗？不会。回报增加了，但回报率没变。因为肥猪丸本身的价格也涨了。当所有人都知道它的价值，价格就会涨到让养猪场的回报率回归社会平均水平。
这就是核心原理：在竞争下，任何资源能获得的回报，会逼近它带来的边际贡献。所有资产的回报率，最终都会趋于相等。
再来看出租车行业的例子。
很多人抱怨打车难，建议降低“份子钱”来增加司机收入，而不涨车费。这可行吗？
出租车服务由多种要素提供：车、油、司机、还有垄断性牌照。你付的20块钱车费，司机只是“代收”——里面包含了车的折旧、油钱、司机工资，还有牌照的“垄断租”。
如果强行降低份子钱，司机的收入看似增加了1000块。但这份职业的吸引力就会提高，更多人会来抢这份工作。他们愿意花近1000块来争取这个名额。结果，牌照所有者会通过明里暗里的方式，把那1000块再收回去。
长远看，降份子钱既不能真增加司机收入，也解决不了打车难。
那怎么解决？双管齐下：让车费自由浮动，鼓励高峰期多出车；放开牌照管理，用共享经济盘活更多车辆。
我们苏州维特瑞纺织，从纺纱到后整理，每一道工序也在寻找自己的“边际贡献”。资源总是流向回报率最高的地方，但竞争会让一切趋于平衡。
最后留个思考：投资绩优股的回报率高，还是垃圾股更高？为什么？
