供给是指生产者或销售者在一定时期内，向市场提供的具有一定数量的商品或服务的供应量。它反映了市场上的供应能力，是供需关系的重要方面之一。

从供给的角度来看，市场上的供应量受到多种因素的影响，如生产成本、生产技术、市场需求等等。当生产成本上升或生产技术难度加大时，供给量就会减少；而当市场需求增加时，供给量就会相应增加。

在市场经济中，供给与需求相互影响、相互制约。如果市场上某种商品的供给量过多，超过了市场需求量，那么价格就会下跌；而如果供给量过少，市场就会出现短缺现象。因此，供给量的确定需要考虑到市场需求、生产成本等多个因素的综合影响。

在经济学中，供给曲线是用来表示商品或服务的供给量与价格之间关系的曲线。在这条曲线上，价格与供给量之间存在一种负相关关系，即价格上升时，供给量减少；价格下跌时，供给量增加。

总之，供给是市场经济中一个重要的概念，它是市场供需关系的重要组成部分。了解供给的含义、影响因素以及供给曲线的含义和应用，对于理解市场经济的运行规律具有重要意义。

What does supply mean?

Supply refers to the quantity of goods or services that producers or sellers provide to the market within a certain period of time. It reflects the supply capacity of the market and is one of the important aspects of the relationship between supply and demand.

From the perspective of supply, the quantity supplied on the market is influenced by many factors, such as production costs, production technology, market demand, etc. When production costs rise or production technology difficulties increase, the supply quantity will decrease; and when market demand increases, the supply quantity will correspondingly increase.

In a market economy, supply and demand influence and restrict each other. If there is too much supply of a commodity on the market, exceeding the market demand, then the price will fall; and if the supply is too small, the market will experience a shortage. Therefore, the determination of supply quantity needs to take into account market demand, production costs and other factors.

In economics, the supply curve is used to represent the relationship between the quantity of goods or services supplied and their prices. On this curve, there is a negative correlation between price and supply quantity, i.e., when prices rise, supply decreases; when prices fall, supply increases.

In summary, supply is an important concept in a market economy and an important part of the relationship between supply and demand in the market. Understanding the meaning of supply, influencing factors, and the meaning and application of supply curves is of great significance for understanding the laws of market economy operation.
