求一篇200字左右的有关市场经济的小短文!（汉语,英语都行）

A market economy is economy based on the power of division of labor in which the prices of goods and services are determined in a free price system set by supply and demand.
This is often contrasted with a planned economy,in which a central government determines the price of goods and services using a fixed price system.Market economies are also contrasted with mixed economy where the price system is not entirely free but under some government control or heavily regulated,which is sometimes combined with state-led economic planning that is not extensive enough to constitute a planned economy.
In the real world,market economies do not exist in pure form,as societies and governments regulate them to varying degrees rather than allow self-regulation by market forces.The term free-market economy is sometimes used synonymously with market economy,but,as Ludwig Erhard once pointed out,this does not preclude an economy from having socialist attributes opposed to a laissez-faire system.Economist Ludwig von Mises also pointed out that a market economy is still a market economy even if the government intervenes in pricing.
Different perspectives exist as to how strong a role the government should have in both guiding the market economy and addressing the inequalities the market produces.For example,there is no universal agreement on issues such as central banking,and welfare.However,most economists oppose protectionist tariffs.
The term market economy is not identical to capitalism where a corporation hires workers as a labour commodity to produce material wealth and boost shareholder profits.Market mechanisms have been utilized in a handful of socialist states,such as China,Yugoslavia and even Cuba to a very limited extent.
It is also possible to envision an economic system based on independent producers,cooperative,democratic worker ownership and market allocation of final goods and services; the labour-managed market economy is one of several proposed forms of market socialism.
