The third factor of production is capital. Think of capital as the machinery, tools and buildings humans use to produce goods and services. Some common examples of capital include hammers, forklifts, conveyer belts, computers, and delivery vans. Capital differs based on the worker and the type of work being done. For example, a doctor may use a stethoscope and an examination room to provide medical services. Your teacher may use textbooks, desks, and a whiteboard to produce education services. The income earned by owners of capital resources is interest.
第三个生产要素是资本。把资本看作是人类用来生产商品和服务的机器、工具和建筑。一些常见的资本例子包括锤子、叉车、传送带、计算机和运货箱。资本根据工人和所做工作的类型而有所不同。例如,医生可使用听诊器和检查室提供医疗服务。你的老师可以用课本、书桌和白板来提供教育服务。资本资源所有者赚取的收入为利息。- 美联储
