Who decides what gets made?
- No one orders a baker to make bread, yet every morning the shelves are full.
- No official assigns you a job, yet almost every job somehow gets done.
- So who answers the big questions — what to make, how to make it, and for whom?
- The answer depends on a country's economic system 经济体制.
Every economic system must answer three questions. Which set is correct?
Scarcity forces every economy to decide what goods, how they are made, and for whom.
Three ways to allocate resources
- A market economy 市场经济: private buyers and sellers decide, guided by prices — no central planner.
- A command economy 计划经济: a central government owns the resources and makes the decisions.
- A mixed economy 混合经济: markets set most prices, but government provides some goods and fixes some problems.
- The pure types are just the two ends of a scale — almost every real country is mixed.
Market, command, or mixed?
Each feature belongs to a way of allocating resources. Markets use prices; command uses a central plan; mixed blends the two.
Which is a feature of a command economy?
In a command economy the state owns resources and plans production centrally.
How prices coordinate a market
- In a market, prices do the coordinating — nobody is in charge.
- A price is a signal 信号: a high price says "this is scarce or strongly wanted."
- A price is also an incentive 激励: it rewards producers who make more of it.
- Adam Smith called this self-organising order the invisible hand 看不见的手 — resources flow toward what people value most, with no one planning it.
In a pure market economy, a central planner sets the prices.
No one sets them — prices emerge from buyers and sellers. That is the invisible hand.
A price does two jobs: it is a signal and an ______.
The signal carries information; the incentive rewards producers who respond.
Every system has a trade-off
- Markets are usually efficient 有效率, but can leave some people behind and under-provide things like clean air.
- Command systems aim for fairness and can chase national goals, but without price signals they often waste resources and slow innovation.
- That is exactly why most countries are mixed — they try to keep the efficiency of markets while filling the gaps.
Match each economy to what it is best known for.
Each system trades something off; the mixed economy tries to get the best of both.
Select all common drawbacks of a command economy.
Without prices to signal value, command systems often waste resources and slow innovation.
Who grows the coffee you drink? No government agency planned it.
- A high coffee price signals that people want more, and rewards the farmers who grow it.
- Farmers, shippers, and cafés each just follow the prices — and the coffee appears on your table.
- That is the invisible hand: private choices, coordinated by price, not by a planner.
An economic system decides what, how, and for whom. A market economy uses prices — a signal and an incentive, the invisible hand. A command economy uses a central plan. A mixed economy blends both — and almost every real country is mixed.
