Opportunity cost is a term used to describe the cost of choosing one action over another. In economics, opportunity cost refers to the revenue or benefit that is forfeited by selecting one option instead of another. It can be thought of as the value of the next best alternative.

Opportunity cost is a crucial concept in decision making because it forces individuals and firms to consider the alternative options available. Whenever a decision is made, there is always an opportunity cost associated with it. For instance, if a business decides to invest in research and development, the opportunity cost might be the revenue lost by not investing in a particular market segment.

Opportunity cost is not always about money. It can also refer to time, effort, and other resources. For example, if an individual decides to attend a football game, the opportunity cost could be the time spent studying for an exam. In this case, the person gives up studying time for entertainment.

Understanding the concept of opportunity cost is essential in personal and business decision making. It forces us to weigh the benefits of each option and make rational choices. A decision that seems beneficial at first may not be the best option once the opportunity cost is considered.

In conclusion, opportunity cost is the cost of choosing one course of action over another. It is a crucial concept in decision making, as it helps individuals and firms consider the alternatives and make rational choices based on sound logic. It is equally essential in personal and business decision making.
機會成本是用來描述在選擇一個行動時所付出的代價。在經濟學中，機會成本指的是放棄選擇一個選項而帶來的收益或效益。它可以被看作是下一個最佳替代品的價值。

機會成本是決策中至關重要的概念，因為它迫使個人和企業考慮可用的替代選項。無論何時作出決策，總是會伴隨機會成本。例如，如果一家企業決定投資研發，機會成本可能是放棄在一個特定市場部門進行投資而損失的收益。

機會成本不僅僅是關於金錢。它還可以涉及時間、精力和其他資源。例如，如果一個人決定參加一場足球比賽，機會成本可能是放棄學習考試所花費的時間。在這種情況下，這個人為了娛樂放棄了學習的時間。

理解機會成本是個人和企業決策中必不可少的。它迫使我們權衡每個選擇的利益，做出理性的選擇。一個一開始似乎有益的決策，在考慮了機會成本後不一定是最好的選擇。

總之，機會成本是選擇一種行動而放棄其他行動的成本。在決策中，它是一個至關重要的概念，因為它幫助個人和企業考慮選擇的替代方案，並根據合理的邏輯做出決策。在個人和企業決策中同樣重要。
