学习通双语讲经济（上）

在当今社会，经济学已经成为了人们不可或缺的一门学科。它是以人们生产、分配和利用资源的行为为研究对象，探究人类社会的生产和分配活动的规律和方法。

经济学的基本原理

经济学的基本原理主要有以下几点：

• 资源是有限的，但需求是无限的。
• 人们会根据自己的利益做出选择。
• 市场力量可以起到调节作用。
• 的作用可以通过政策来体现。

需求和供给

需求和供给是经济学中的两个关键概念。需求是指消费者对特定物品或服务的消费愿望和能力。供给是指生产者为满足市场需求而提供的物品或服务。

需求和供给的关系是决定市场价格的关键因素。当供给量小于需求量时，价格会上涨。相反，当供给量大于需求量时，价格会下降。

市场失灵

市场失灵是指市场力量无法解决资源分配问题，需要通过干预来解决。市场失灵的原因有多种，其中包括外部性问题、公共物品问题、信息不对称、垄断等。

税收和财政政策

税收是指向市民征收的财政收入，主要用于公共事业建设和社会保障。财政政策是指通过调整支出和税收来影响经济运行。

货币和货币政策

货币是指在市场交易中广泛接受的支付手段。货币政策是指调整货币供应量来影响经济活动的政策。

国际贸易和全球化

国际贸易是指不同国家之间的商品和服务的交换。全球化是指市场、生产和投资在全球范围内的日益增长和相互联系。

通过加强国际贸易和全球化，可以促进国际间的贸易合作和经济发展。但是也需要防范贸易保护主义和资本主义的不平等。

总结

经济学是一门研究人类社会经济活动规律和方法的学科。它的基本原理包括资源有限、利益驱动、市场力量和调节。需求和供给是市场价格的决定因素，而市场失灵需要干预解决。税收和财政政策、货币和货币政策以及国际贸易和全球化是经济学的重要领域。
