量价挂钩：价格与数量的紧密关系

中文版

在经济学中，“量价挂钩”是一种描述商品或服务的价格与数量之间关系的术语。这种关系意味着当商品或服务的数量发生变化时，其价格也会相应地调整。这种挂钩机制是市场经济体系中的核心要素，它确保了供需之间的平衡。

“量价挂钩”反映了市场的基本规律，即供求关系。当市场上某种商品或服务的供应量小于需求量时，价格往往会上涨，因为需求者愿意支付更高的价格以获取有限的资源。相反，当供应量超过需求量时，价格会下降，以吸引更多的需求者。这种自动调整的机制有助于维护市场的稳定。

在实际应用中，“量价挂钩”也体现了企业的定价策略。企业通常会根据市场需求和自身成本来制定价格，并通过调整产量来应对市场变化。例如，当市场需求增加时，企业可能会提高价格并增加产量，以满足更多的消费者需求。

Price-Quantity Linkage: The Close Relationship between Price and Quantity

In economics, "price-quantity linkage" is a term used to describe the relationship between the price and quantity of goods or services. This linkage means that when the quantity of goods or services changes, their price will adjust accordingly. This mechanism is a core element of a market economy system, ensuring a balance between supply and demand.

The "price-quantity linkage" reflects the basic laws of the market, namely the supply-demand relationship. When the supply of a certain commodity or service in the market is less than the demand, the price tends to rise as demanders are willing to pay a higher price to acquire limited resources. Conversely, when supply exceeds demand, prices will fall to attract more demanders. This automatic adjustment mechanism helps maintain market stability.

In practical applications, "price-quantity linkage" also reflects a company's pricing strategy. Enterprises usually set prices based on market demand and their own costs, and respond to market changes by adjusting production volume. For example, when market demand increases, companies may raise prices and increase production to meet the growing consumer demand.
